Brake pedal buzz at stops - ABS kicks on at stops - Cleaning Wheel Speed Sensors - GM Truck

- ABS problems! Let's look at why my trailblazer brake pedal buzzes when coming to a stop. The anti lock brake system activates at stops. Unwanted low speed ABS activation is super annoying. The ABS has been activating at every stop under 5 mph, even in dry conditions. No codes or warning lights. It's a typical GM truck issue, and it's relatively easy to fix! All I did was remove and clean the wheel hub and wheel speed sensors. No more brake buzzing!

BRRRRRRRRRR! That wasn’t me! It was the brake pedal. Honest!
Great work! A little antiseize compound on the hub surface might hold off the rust for a little while. Thanks for sharing!
curious did it make this sound when shifting from drive to reverse when lifting off brakes as well?
@@charibroden2668 no. Never noticed mine doing anything like that.
Really? Your missing the c/v shaft retainer, that is a big problem, will damage bearing.
@@baukesikma9374 good eye, but it wasn’t missing. I removed it. I replaced the cv shaft later.
I do not usually comment on TH-cam but today was the exception. After wasting hundreds of dollars on mechanics to fix my buzzing issue which they could not figure it out . Also the Toyota dealer wanted $1,000 to replace both front ABS sensors to fix my brake buzzing issue. I was able to follow your advice on your video and today I finally cleaned the rust between the hub and the ABS sensors. My buzzing issue disappeared. You saved me more money because I was going to replace both sensors. I drive a Toyota Sienna 2008 LE. Thanks for your video.
TOYOTA $1000 ,ARE THEY NUTS ?. $100 BOTH SIDES BRAND NEW ROCKAUTO PARTS.
Hope I ca do the same
Thank you for this video. That noise had been driving me crazy. Ive cleaned my rotors, greased up my caliper pins, changed my pads and the noise and vibration in my pedal was still there. No one told me abs needed maintenance.
To anyone that put a thumbs down is an a$$hole. I can’t imagine someone being upset with getting free and helpful information. Wanted to thank you for your video. Worked for me on a Toyota. Cleaned all the rust with WD40 and small wire brush. Then used the mass air flow cleaner on sensors and the issue went away. Driving much better. Thank you again.
Its nice to get that kind of info Bravo 😊
Thank you I'm a disabled senior, and I've been trying to describe this to my mechanic and my brother for 3 years. They told me it was ABS and I kept saying it grinds almost every time I stop. 2005 Trailblazer. Thanks again, I;m sending your link to my brother.
I have been trying to figure out why my Silverado has been doing this… you have solved all of my problems!
just some minor additions:
1.) you don't need to loosen the brake caliper first and the bracket after that. Just unscrew that 18 mm bolts and take off the whole assembly in one step, saves time.
2.) after removing the rust scales and cleaning up the area where the sensor sits, use some grease or just a thin layer of spray paint to prevent it from rusting right back up again. will make it last longer until the next exakt same procedure
Other than that, great video and keep it up :-)
Thank you for the additional tips! I was wondering why the brakes had to be taken a part the way he did it in the video and it turns out you don’t have to do it that way.
If corrosion has lifted the sensor because it sets off to the side of its bolt and his plastic I wonder if you could heat it up just enough to Arch it so you know it's an all the way
Straight to the point. Thank you for no filler
YAY! I may have an answer to wtf is going on with my Failblazer. She is a 2002 with well over 223,000 miles.
Weird crap like this happens off and on. She has WAY too much life in her to give up on small problems!! I truly appreciate your videos. This wasn't the first one I used as a reference, FYI. XOXO!
I feel a real connection to other TB owners who have the same problem. I’m going to try this this weekend. It’s a bad sensor festival under there.
This video saved me a lot of money. Schwabbies wanted to replace all my brakes, then do an alignment to “possibly fix the problem” THANK YOU!
Great explanation of fart noise in abs. My Cady has same issue. I will fix it thanks to your tutorial.
Mechanic told me it was a bearing and it was about 650.00. You should have seen the look on his face when I told him that i just had them replaced. Now I finally know what it is
😂
Thanks for the helpful video! My Toyota Prado TZ 1997 was having the same issue, but after watching and following the steps, I removed the fuse to check then cleaned the sensors. Test run was a success and the problem is now solved. Much appreciated!
ABSOLUTELY WORKED BRO! Even on my Jeep GCL! I been having this issue for over a year so I did the breaks then the front rotors then the back then the calipers! Then everyone is like it’s a warped rotor so I took my rotors back and STILL HAD THIS ISSUE! Was on TH-cam all day doing research and was just about ready to quit and I’m like I’m gonna watch one more! And that was you! And thank god I did! Pulled the fuse and that thing CAN STAY OUT LOL THANK YOU SO MUCH! If ur ever in Toronto I owe you many beers
Glad the vid helped!
Did your pedal feel like it was spongy
@@dudleydorite7678 not at all! Was just a serious pulse in the pedal! Pulled the abs fuse and STILL good! This was 2 years ago!
@Ziggy Sins man I've been chasing kinda same problem on a dodge avenger when stopping that abs will kick on. Even on dry pavement.
Thank you. Same problem with my 02 Blazer. Driving me crazy and stress thinking having to pay $$$$$$$. Saved me bucks. Thank you so much.
I'm glad I came across your video. Just picked up an 02' Trailblazer myself. Noticed that it does this as well. Will take care of that myself when I can. A little cleaning goes a long way!
My 02 trailblazer just started doing this I also notice when I’m turning into my driveways at low speed while pressing on the break I’m going to follow these steps thank you!!
I’m having this exact problem in a ‘12 Chrysler 200. Mechanic told me since abs module isn’t his forte said dealership needs to look at it. Woulda cost me 120 for diagnostic and the abs module replacement almost 1500. Im trying this tomorrow you might have just saved my life bro lol
This is brilliant. Much more useful than "light equals bad" as most others say.
Great video. I have the exact same issue and can't wait to try your suggestions (on a warmer day, got the fuse out for now). Very clear video and to the point. Thanks!
Exactly what is going on with my 03 Silverados ABS system. Nice video now I know how to fix it. Thank you.
Same here, did you ever fix your 03?
@@LightYagami-qq9ry yes I did just cleaned the sensor works great
@@JD-526 okay now I know, I’m dealing with the same issue with my 03
@@LightYagami-qq9ry pull you wheels off the front and you will as I did rust build up around the sensor. Clean it and you will notice that the vibration in the break peddle stops between 5 mph and 0 mph. You most likely will not see a code for this problem unless it has to do with you ABS. Another thing you can do is unplug the fuse to the ABS and see if this problem stops, I think this is in the video.
So one light off and two to go LOL ! Thanks for posting the status is very helpful we appreciate people like you 😇😇😇
Thanks, I have this issue as well. Now even if I can’t fix it myself, at least I won’t feel like such a dumbass when I go talk to a mechanic.
Nice straight forward video by the way.
This is the video i was looking for its just what my 05 gmc Sierra has been doing .. i just removed the fuse and it stopped doing it thanks you so much bro
Thank you for this. Mine does it. Quite annoying, especially when pulling up to the fuel pump and everyone around can hear the noise.
I’ve been trying to find info about this for a week now. Thank god I came across your video. I have a 2005 Hyundai Santa Fe that’s doing this
Thank you! Exactly my symptom on my 94 E150. Will be doing this next week.
Thank you brother! I changed the wheel bearing assembly with a new one but the harness was different. I switched the harness from the old one to the new one thinking it should work, wrong. The thing is I put new brake pads all the way around so I didn’t know what was going on. Pulled the fuse and the frog 🐸 sound went away. Fixing this problem in the morning with the correct part. Thanks again. This was on a 2005 Yukon.
I like your format for what to check first then what to check next.
Thank you for this! Mine was activating at 15mph. After watching this and replacing the sensor, i found that putting the factory shim on the aftermarket sensor was no bueno. Took the shim off and it's now doing it at 5mph. So mine is still a clearance issue between the magnet in the sensor against the tone ring inside the hub assembly. But this video got me on the right track. Thank you!
Thanks !!! I replaced both my hub bearings on my 99 Blazer and everything was fine for awhile then I started getting the brrrrrrrrp . Gonna try your remedy tomorrow. I was down to thinking it was the brake booster because of the noise and location it was coming from but your video has helped me think otherwise. You Wouldn't think with 2 brand new hub sensors that I'd have a problem but it does exactly what you were experiencing. Thanks again.
I used to do all repairs my self but as I get older I find that I prefer to pay someone else to do it SOMETIMES. It gives me more time with my family and thats worth all the money in the world.
@@Azureecosse I get it. I have invested in the tools as well. I am financially stable enough though that I can support mechanics. I like to support the local guys so they can support their families as well.
@@Azureecosse as long as you enjoy working yourself it's good I do all mechanical job myself and I enjoy too I always accept the challenge my brother have abs issue too hopefully tomorrow we will fix it and enjoy free lunch with family tougher Happy new year U Tubers
Thanks for making this video, got some work to do.
I experienced the same issue but thanks i sorted it out. I replaced the Abs, and break pads but with no change. Someone told me to remove one of the sockets in the abs and it just worked. Just try and see
Thanks for the video you put on TH-cam. It help me fix my ABS sensor issues. Keep up the good video bro.
You rock bro! You just saved me $$$$ on repairs
Thank you
John Mishler awesome!
@@TheDaninator I have a honda civic 1.5 turbo 2017 and whenever i apply sudden brake to stop the car immediately whether at the speed of 20 30 or 100 the abs kicks in immediately brakes lock up and car skids forward and abs system does not show any fault code what could be the issue? I have new pads rotors front back and almost new tyres michelin primacy 4 so everything on that side is clear i am just not able to fix this problem now i found this video i wonder if its the same issue? With my sensors causing abs to kick in ??
My 1999 Tahoe does the same thing intermittently and thanks to you I now know what it causing it. It scares me when it happens because I'm so afraid I'm going to hit someone's car.
Very common problem! It's a butt-clencher when it happens for sure!
@@TheDaninator or cheek fuser 😂
Damn it, i think you just saved me. My Honda doing it after 2 months doing my brake job.
I have the same problem on my 07 thank you so much for the video
Thank you. Having this same problem in my trailblazer just changed pads and rotors all the way around and was going to get new calipers and brackets all the way around thinking that must be it. You just saved me money and time
Awesome! Happy repairs.
Thank you! Exactly what I needed!
Thanks man for this video a lot of info .. I was going through so many videos and yours give me the best shot to fix my yukon brake problem again tanks so much.
Glad the vid helped 👍
If you spray some Rust-Oleum on before you put sensor back on it will help from rust build up in future as well. Nice video. Very helpful for me and my '02 trailblazer
Not spraying the sensor but where it mounts to the hub.
nice tip
Thanks Dan
I know what I'm doing on my 2004 tahoe tomorrow.
Thanks for posting
My Camry does this, same wheel. Installed a new sensor, it still does it. My hub was like new, no missing teeth and no rust at all, that's why the new sensor but still no luck.
This video helped me so much! I just replaced the bearings, rotors, brakes, calipers, and control arms. Once I put it all back together it started having this issue. I just ordered a new sensor so hopefully it works.
In my case the bzzrrr noise still kicks in when I brake at at 4 mph, I got a new abs changed, cleaned it up even though there's no abs light coming on the dashboard in the first place. What situation might this be
@Richard Azuama replace speed sensor.
Did it solve the issue
Good work 👍
I have an 07 Envoy that's doing this annoying crap! Thus how I found your video/channel 😊Gonna take my old gal apart tomorrow and see if this trick fixes the buzzzzzzugher sound every dang time I come to a stop
good thinking .. nice video ..I would have brushed some anti rust protection on all of that corrosion . You got lucky with that plastic pickup sensor . I have had issues with my abs module making the front brakes drag . I have a scan tool Foxwell NT630 Plus .. which does abs bleed and more .. I imagine what is happening is that the modulator dump valve is stuck after I fitted new pads and did a brake fluid flush / replacement . Using the scan tool I can hear the various valves clicking but when the scanner asks for the abs on off the disc is so solid that it is not possible to turn the disc by hand .
I have this exact same issue! Thanks for posting this. I will try the same steps.
Good video. Swapped out the sensor, still doing it. I'm gonna try to reinstall it and clean it really well like you did here.
I cleaned the heck out of mine, filed down the metal to get rid of all rust, changed both sensors. Still does it. Did you solve this?
Thanks a bunch this video helped me fix my truck!
Awesome👍
Thank you brother man was going crazy trying to figure it out 02 Silverado was doing the same thing . Pull the fuse out going to leave it out
Same happens to me in my 2000 Camry gona try cleaning the sensors and giving it a shot
Thanks got same problem on my A Class started couple days ago,
Nice 👍 same problem. Going to fix it as you did.
Great video! Thank you! Removed the fuse, and the brake sound went away, peddle still feels weird though… I have an f150 ecoboost lariat 4x4 - any idea how to determine if its front or rear sensor?
My 04 Civic hs same thing when I replaced ball joint and put it back all together, after a week using it it started acting up tge abs, maybe I need to clean the sensor before putting it back, thanks for your video
Thank you. That's definitely my problem. Not sure which sensor, but this is a big help.
thank you! this has been driving me nuts since I got my 99 avalon. shop couldn't seem to figure it out.
Thanks a lot. Got crazy about the noise. Hopefully l'll solve. Thanks
Thanks great information. Straight to the problem.
Thanks for this video. Could the rears be the issue or is it always the front?
There are no speed sensors on the rear of the Trailblazers.
A have the same problem right now on my Toyota Camry 2016.
Same 2014 Camry my sensor had rust on the tip and there was build up on where it mounts. I’m watching video after I already cleaned it but hopefully works
hi this is great just one question ... is this the same abs sensor location in both 2wd and 4wd trailblazers ? thanks
I went to local mechanic and this issue popped up immediately after he was done changing a support beam on the drivers side. Im wondering if it possible he somehow sabotaged the abs system by showing gunk into the sensor or something like that.
I have a similar issue on my '95 Audi A4, except it's at all speeds. The ABS light isn't on. I'm gonna go check the sensors and the ABS rings. Let's hope it's nothing else serious.
Edit: I cleaned the sensors on the front wheels and it worked! Took a drive around the block and the brakes were working normally.
Thanks man didn’t even think to just take out my abs fuse haha im just gonna run it like that
Still running like that?
@@chambliziOfficialChannel yup lol
@@garrettisamess509 cool i did the same screw that abs back in the day they didn't have that had to shut the engine off to unlock the brakes its better loosing pedal pressure and rear ending someone
very cool fix my friend, I just picked up a 2008 trailblazer that does the exact same thing. going to try out this trick and hopefully save a ton of $$$ thanks for the great video !
Merci beaucoup! J'avais le même problème sur mon Ford Ranger 2008. J''avais déjà vérifié les deux sensors, ils testent ok. Je comprenais pas le problème. J'ai fait comme dans votre vidéo et ça fonctionne. Merci beaucoup!
Thanks for sharing and tipping.
Great idea. But heads up.ive read discussions about driveing without ABS Its very dangerous in a sudden stop can prevent scidding out hiting a car.
Absolutely true but ABS does Increase stopping distance by releasing the brake that's causing you to go out of control
I used to think that that sound was caused by some dirt on the brake mechanism because everytime I have my car cleaned, I don't often hear that sound. Now I think the dirty sensors might just be the culprit
GM had a bulletin out on this. You did everything they said except. It said to use a pencil eraser down the sensor hole and turn the hub to clean the inner surface. If I remember right it did say apply a light coat of grease to the sensor base.
The rust jacks the sensor up and creates too big of a gap for the sensor to make a proper reading.
exactly what I was looking for!
Thank you so much, this fixed my problem!
Thank you so much, that is my problem but I have to take it in...too bad you don't live close by. I hope they don't charge me too much..how much do you think will cost? and how danger is to drive like that?
I drive a 2014 Hyundai Elantra..whenever I’m driving slow the abs light goes off but when I drive fast it comes back on..When the Abs light is off I hear grinding noises on the driver side when I apply brakes but when the abs light comes back on and I brake I don’t hear any grinding sound(grrrrr). Changed my wheel speed sensors twice and rotor. driving me crazy. I will try to clean any rust like you said. I hope it works
Update..So I cleaned the hub and sensors on both sides like he said and it actually worked. Wow I’m really surprised..Thanks man you saved me a lot of money
Just started the video but I had the same issue in my 2007 Corolla! Now it’s completely stopped but ABS won’t function. Brake, abs, and tire pressure warning lights are on. Let’s see if this helps in cleaning the sensors
Worked on my 2007 gmc classic. Thanks
Ah yes, typical random Check Engine Light on a TB. Sensors on those early TB's suck or something :D
Hey Daninator! Your check engine light was on after you fixed the symptoms. Was the check light on because of the dirty ABS sensor or was that a different issue all together? I ask because I have a 2003 Trailblazer LTZ that has the exact same problem. At every stop that before the vehicle comes to a holt, brake pedal buzzes and vibrates a little. But I didn’t get a check engine light on mine. Only time it doesn’t do it is if I come to a stop super slow without applying much peddle. I work on all my own vehicles as long as I have the tools and the time to do so. Very helpful video! Much oblige!
I don't believe the check engine light was related to my braking issue.
Ok I feel better about it knowing that your check light wasn't related to the ABS issue. Now I don't have to wonder why I didn't get a code and someone else did for the same problem. Thank you for taking the time to reply.
@@fredwagner7424 mines been doing the dam same thing i replaced the hubs with sensors and problems still there sucks man next step is replaxing all the dam lines and module
M
Hello M. Yeah that kinda sucks after all that work. I haven’t gotten a chance to try fixing mine yet. But I’m driving to work tomorrow morning because we just got slammed with snow and ice. I’m still going to try cleaning the sensor first and take it from there. I’ll let you how it goes. I’m your case, after what you’ve done already before I would buy anymore parts I would try bleeding the brakes. Unless you already tried that. That’s what I was going to first try until I seen his video. Only because the peddle seems to go down farther than normal when that happens. It never happens when I use the brakes any other time. Only just before a complete stop does it does it. If I’m able to brake slowly and creep up to a stop with having to push to hard on the brake peddle, I doesn’t do it. That’s why bleeding the brakes came to mind first. Real spongy feeling and the peddle almost goes to the floor, then I get the fast pulsating action and sound. I’ll keep you posted!
Excellent - thanks for sharing.
i have a trailblazer too. i recently had several suspension parts replaced. after the job. i was experiencing the same. i had to disconeect the abs sensors in order for the brakes to work properly. so the trick is to clean it like you did in order to work?
Removing any rust scale and cleaning the surfaces should certainly help
@@TheDaninator i follow your steps, and it worked! thank you.
Cool. Thanks for the video.
Thank you sir mechanics tried to charge me a arm and leg saying i needed new front a back sensors.... Whats your check engine light on for?
Mike Malone something to do with the EVAP system
Change your gas cap just got done with that b.s. and thank you for the advice i just pulled my fuse i dont like abs.
Pulled my ABS motor fuse, that BS stopped right then and there :)
If this does not work...Try a HARD RESET(disconnecting one battery terminal for a while)it works on my rav4 2004...thats one my friends idea.What a relieve for me...save me a lot of time and $$$.
Thanks for this tips though.
Thanks for making this video bro!
Will this also cause abs light on dash?
I guess my 2015 Toyota Corolla had the same symptom you mentioned.. luckily my car is still under warranty... Just send to my Service Center and tell them.. thanks
Same exact problem. Thx! 👍
Did your rpms fluctuate at all? Did you feel a grind in the pedal?
Im going to try to see if the abs fuse being out will give me an idea of what is going on.
I replaced the abs sensor 3 months ago as the light came on. It fixed it, but then I got this current issue of brake pedal grind and rpms jumping. Another abs sensor replacement gave my truck a solid week with no issue.
Hope it isnt a module or something. May just run it without any abs nonsense.
How it turn out?
@@williamharper9356 It was the bearings/hub assembly needed to be replaced. Not abs sensor related. Tool 45 min for them to hammer it off on the lift. So if one abs sensor doesnt fix it, it is the hub. Running without abs is obviously not an issue.
Good Explanation that makes sense, If not set correct air gap it may jump down speed so thinks its lost traction and abs kicks in
Same thing with my last envoy , I removed the fuse
I got stopped at trying to get the caliper bolts off. Didn’t realize it would be hard as hell to get off 😂
Interesting to watch! However when your steering wheel went right on stopping, and you said to do the opposite side sensor, why did you do the RIGHT sensor not the left?
I did both. I started on the passenger side, only because I had the wheel off doing a different repair. Just figured on going ahead and cleaning both.
You do the opposite on which way the steering wheel pulls because the steering wheel is pulling right due to the abs kicking in on the left side and the pads not completely grabbing the rotor.
SERVICE ENGINE. LOL. gonna pray mine works. you still have yours?
My Toyota Tundra is doing the same thing but it didn't do it until I replaced the ABS sensor.
