How to change brakes on a semi truck

- Quick video on how to do brakes on a semi truck or trailer. The concept is the same for the steer axels, drive axels, and trailer axels. The only difference would be, some slack adjusters take a 7/16 wrench or socket vs the 5/16 eight point socket I used with the cutters to pull on the safety pin. Feel free to comment below and ask any questions you guys may have and I'll be happy to answer them. Please like, share, and subscribe, thanks for watching.

I do this for a living. The struggles were left out of the video 😂
One thing I recommend doing is clean your s-cam off! Any grease on it will cause rollers to slide and flat spot the s-cam. And while you’re in there check s-cam end play and bushing wear by pulling in/out and up down. And also check where the old ones were riding on the drum before removal. If they’re walking off the drum you may want to get a s-cam rebuild.
Thanks bro I’m a driver but I wanna learn to do the basics on the truck 👋👋👋👍👍👍✌️✌️✌️✌️✨✨✨✨🙋♂️🙋♂️🙋♂️🙋♂️🙋♂️
Thanks man. As an apprentice I found this very helpful.
One of the best videos on semi brakes thank you
Using the wire cutters is brilliant, I've never seen it done like that.
Excellent Video.. got to
start doing my own breaks and seals..
That's Awesome! Pretty simple step's! Only thing is to be safe!
Thanks for the video. Very helpful!
Great video. You made it look easy. Nicely done sir
Thank you for helping me. Thanks for making it simple
Badass video homie keep hammering down!!! Big dawg...
Thanks! New O/O here and REALLY don’t want to pay that mechanic bill for something I can do myself! 👍🏻
your amazing doing this with one hand without cussing
Great video and great job with the tools you had
Thanks for this video bro.i have a toyota tacoma truck and it have more springs than a semi truck for real 😊.
Great video brother. I like how easy you made it look. I try to fix everything I can on my trucks bcoz these shops charge an arm and a leg to do the work and the mark up all the parts.
Thanks for the video nicely explained. Greatly appreciate it
Good video easy to learn the way you explain
Thank you well done and very informative
Dam homie you made changing truck brakes look simple as hell
Only thing I would recommend is use some copper grease between your hub and drum and then again between wheel and drum, just makes it easier next time you come to change them, good job
Great point Greenboff, I'll be sure to use some the next time I take them off. Thanks for the tip 👍🏼
Definitely gonna subscribe to your channel
An over-the-road driver friend had his own trucks and he would change his own flatbed trailer brake shoes and service his (oil-filled) hubs and hub seals all without unbolting the 8 dual (10-hole Budd wheel rims, with their tires..) from the hubs. He'd put a piece of clean 1/4" steel plate (of adequate dimension, and lightly greased on the top surface) underneath the duals. Adjust his jack so the tires/rims/hub/drum assembly was just sitting on the greased steel plate (no trailer weight). Drain the hubs and remove the spindle nuts and slide the whole deal straight off the spindle on the greased steel plate. Change out the shoes and whatever brake parts needed, check the oil seals and slide the whole thing back on. (of course, this only works assuming your bake drums are still okay and don't need changing....). Saves a good bit of time.
Only resone you would pull the duels off together as you say is if your going to do the brake job and wheel seal
Add didn't think that the air tanks on a truck would take lug nuts off with a big inch drive I'm glad I see this video
Good work How to serg,
I love simple man-mechanic stuff. Be thorough and pay attention to detail. All else will fall into place. Good job sir.
BTW, I'm a big fan of "Never Seize." Copper or nickel based formulation, both are fantastic.
Thanks for the feed back and tip Scott I'll be sure to ask for some the next time I take my wheels off.
Im gonna try that wire cutters slack adjuster trick tomorrow at work, nice...
Nice! Let me know how it goes Danny 👍🏼
Or just buy the correct brake tools. Not sure if you know but they make tools for adjusting these type of slack adjusters
Could you please let me know how do you install same air set up for volvo..
Man; thanks for the video.
No problem thanks for watching Raymond
good video. thank you
Thanks for the feed back the greek guy viva-greece
Thank u sir.
That was EXTREMELY helpful. Thank you very much for an excellent video. And I agree with the others you made that look very easy, and I know that it usually is not that easy. You are good!
Good work.. liked the video... better to do it your self one trying to charge me 200 dollars to do one brake pad no drum
What kind of jack is that? How much weight does it hold
Good video,thanks. Do you buy new shoes every time or do you have your shoes re lined? If you can't find copper grease there is a great alternative in plastilube moly. It is a high performance synthetic grease that was specially formulated for brakes. Good blast down with the steam cleaner required to get all that shit off your suspension!
Thanks for watching Andrew, I buy new ones every time, only cause I don't know of a place that can reline them for me. Depending on the brand they can go as cheap as 35 dollars a wheel and as much as I've payed is about 70 dollars per wheel, but that's for better brakes. The cheaper ones seem to crack, squeak and wear out faster, but that's a matter of personal preference. Thanks for the recommendation on the copper grease and the plastilube, I'll be sure to ask for some the next time I'm at the parts store 👍🏼
Good video, only one thing. No cribbing blocks under it? I'm a passenger car/lt truck mechanic. Regular vehicles I use jack stands, when I need to lift something heavy I use railroad ties that chainsawed into 2 foot sections.
since your brake drums were not exactly centered, were you getting a vibration or bumping from them going down the road?
Awesome
Buena chambita carnal👍
Gracias Mario
Best video
Great content. How often do you need to replace the break shoes?
What would the average shop charge for this job?
I've only worked on 4 wheelers and I hate drums, discs are so easy.
Stay safe and profitable. 😃
Thank you John Beckman
It's been a while since I've had someone else do my brakes, but I think they run anywhere between 750-950 for brakes and drums in the back, but I could be wrong. I think labor normally runs about $100 per axel plus parts. If someone knows otherwise please feel free to comment.
Ave. is about $136 per axle plus parts that shops will charge double. Do youself will save at least 250 bucks per axle.
So aren't you supposed to adjust the s-cam back or does it adjust itself?
Caleb Favela yes you’re supposed to adjust them yourself, if you fast forward to 10:35 you’ll see how I explain how to adjust them : )
I have a 1in air impact as well would i still have to torque it ?
I always give them about a 1/4-1/2 turn after the lug hits the rim on the first round and then I come around and hit them for another half turn after that. You’ll need about 450-500 ft lbs of torque which a 1” should have plenty. I’ve been doing it for almost 15 years and never had a problem.
I certainly would.
good job
it is much easier than mercedes and man
Mahmoude Gaber in my opinion yes these are easiest brakes I've ever done.
I'd like to see that 1inch Impact running off your truck air tanks.
I'll be sure to record it on my next video 👍🏼 bubba JusTrucking
bubba JusTrucking it will run fine off them. I've done it. It runs great just not long, at all.
It works well but you will need to take breaks and let air tank fill up several times. Aslo you must use 1/2 " hose from tank. Standard hose you buy that hook up to glad hands will not provide the air volume needed. I've been doing this for 20 years.
👍🌷
Are you from Chicago? You're Puerto Rican for sure.
Should always change anchor pins and bushings. This is why you should leave this to us qualified mechanics.
Pls vedeo hand break repair truck
Ya bro you need to remember them jack stands and scotch a tire or two. Better be safe than sorry. Im a tractor trailer mechanic of about 25 years. I'd also get the proper torque wrench and torque them nuts on steers and drive tires. 500 foot pounds
How to know when is time to change the brakes on a semi? Happy Thanksgiving bro.
So much easier than pedestrian drum brakes!!! 😥
save yourself 200-300 $ for a brake job. but a 1" impact is around a $700
amer a3a2 I payed 175 for that impact back in 2011, I've done many brake jobs and tires with it. I agree 1" impacts can get expensive if you don't do your research, but if you shop around you can also save money on doing the brakes, tools and parts.
How to serg
175?? shit the cheapest i've found is $650
cheers
amer a3a2 you gotta look around i found mine from this old retired guy who was giving away all his tools i got mine for 85 back in 2014 and still works like a charm
Harbor Freight has several 1" impacts from $100 to $300. I run same off my truck air tank with 1/2 inch hose. Have saved 10s of thousands of dollars over the last 20 yrs. By doing my own brakes, changing tires and blow outs on the road. One road call to fix a blown tire is at least a thousand dollars.
For starters how about a jack stand and not trust a 50 cent o ring to support the truck. A pair of pliers to release the lock on that mertoir slack is just wrong go buy the correct tools. These videos are what give good journeyman techs a bad name U get what you pay for this is the fourth video I’ve watched tonight bored and let to see one done correct It’s just sad
