- Changed your Brake Line and now your Brake Wont Build Pressure?
Flushed your Brake Fluid and now you cant Bleed the Brakes because No Matter how many times you pump, the system has no pressure ?
You Pump and Pump and Cant Bleed Your Brakes the Traditional Way ?
Its an Easy Fix, it just takes a couple of minutes, and gravity is the only tool needed.
This also helps if your brakes just feel spongy

Thought I wasn't going to accomplish my goal of riding to work Monday. This SAVED me.
Thanks a lot man! I definitely was too used to bleeding car brakes. you helped me out of a huge pickle. I hope good things come back to you in life.
After 30 minutes of pumping and nothing happens I’m like I did something wrong in my installation but let me TH-cam it first and you basically save my day thank you so very much
Damn man. Good shit
I’ve never seen this method.. it’s always use the brake bleeder and a plastic tube 😳
OK, I wrestled with this LITERALLY for days and could not get any air bubbles to appear. So much so that I figured the brake line itself was bad. But what DID work, and Instantly, too, was reverse bleeding, using a syringe to pump fluid IN from the bleed nipple with the master cylinder cap off. Had all the air out and a firm brake lever in 1 minute!! So if this video doesn't work, try the reverse bleed technique. You just need a plastic syringe full of brake fluid. Easy.
That's what iv been doing all day today now I find this now lol I know what to do now . I don't know if this is the reason I can't get bubbles out as I'm trying to bleed the brakes on a motorbike like i would on a car an why its not working .
So thanks for posting this vid hopefully I fix the prob .
I think I have bad line. No air bubbles and reverse bleed would not go in. Kept popping of stem and brake fluid went all over rims and floor.
But the last inch or two of fluid is what gets beat up. If you reverse bleed, you are pushing that further into the system
@@shogun678 You push it all the way through the system and out of the reservoir.
@@shogun678 Exactly! You will get crud in your fluid, and it will migrate to the bottom of the line. WORSE, if you have abs on your bike and you push that crud up and through the ABS box, you can destroy it. I like the theory of the reverse bleed, but you're definitely want to drain the bottom few inches of fluid first. The other thing that was really hard to wrap my head around was why bubbles can migrate to the bottom of the line when bleeding. It's because there's more pressure up near the master cylinder than down at the slave, and the pressure differential can overcome gravity and the bubbles move down to get away from the master cylinder. This is why putting a zip tie on the lever overnight and then quickly bleeding as soon as you remove the zip tie will have bubbles coming out the bottom.
I thought my master cylinder was bad. Ever video I watched said full pulls. I pulled on that lever for 45 min. My hand was cramping up. I ordered a new master cylinder and then found this video. It worked, the small pulls had air bubbles rolling out. Thank you. Canceled my order for replacement master cylinder.
Man… that LITTLE detail, of not “squeezing” the lever… Gold!
Thank you so much for doing this video, I've been messing about with my front caliper and stripped it down now about 10 times trying to find what I did wrong rebuilding it and why for some reason i can't bleed it. Turns out I built it all correct and after watching your video 30 seconds later I have pressure, if only i'd looked at this 5 hours ago. THANK YOU again
I recommend doing this again after a short ride. The vibrations from the engine and road will loosen any mini air bubbles stuck in the line to rise to the top. Keep the lid on the master cylinder, but do the mini bump process again. Super small bubbles will continue to empty out of the lines and you will have the best feeling lever possible.
You can also zip tie your brake lever overnight. The pressure will help get out a lot of air.
I NEVER would've EVER considered those tiny micro bubbles a factor until seeing this video. My lever went from almost touching the grip to barely compressing an inch. Thanks so much compadre!
thanks for the video, brother.
yesterday I went for a 75 mile bike ride around Napa. at my turn around point I realized I had a front brake leak. I took it easy going home but when I was about 1 mile from my house my front brakes had bled out and had no stopping power. my rear brakes were all I had to go with. The Road Gods were looking out for me.
Didnt work for me, did this for an hour and bleeding it 12 times. Theres always a tiny bubble
Many Thanks for this video!! Been chasing my Tail with this
Hey man, thank you! I killed two hours last night trying to bleed the front brake on my WR250R (using the traditional method) after rebuilding the master cylinder, and I was making zero progress. Like another comment said, thirty seconds of this method and my brake lever has better feel than ever. One point of advice, besides turning the bars so that the master cylinder is the highest point, I also secured my brake line so that it was lower than the master cylinder as well (dual sports like mine loop the brake line up over the bars and cockpit area). Using your method plus occasionally opening the valve on the caliper like I'd been doing has been a game changer.
I lOve you damn ashole😂😂😂 you help me i try 12 days to make it until i see your clip damn you are king
You’re an absolute BOSS! Thought I was sold a bad master cylinder, but your tip had me up and running in minutes! Thanks!
I'm feeling the same way! Looking forward to trying this technique tomorrow!
Dude, you are a freaking lifesaver. I wasted 2 hours on the RevZilla videos before you ended all my problems. Thank you thank you thank you. Saving this to my reference playlist forever.
great tip and i love the Nighthawks
EXTRA TIP (from what i've found doing this) is to gently tap the lever while steering left-right-center to more thoroughly get the air out of your master cylinder. Careful not to spill it though!
Great video. Appreciate it.
OMG YOU ARE A LIFE SAVER!!
I was just getting ready to order caliper parts for a rebuild, because I bled it for 2 days and got no pressure. I went out and tried this and had brake pressure in less than 4 mins!! Gonna bleed it this weekend thanks again!!!
Thanks flushed my break fluid for the first time. You are a life saver.
Finally a video showing the fix for no pressure at the lever after fluid replacement. Thanks
I have struggled to bleed certain brakes (KTM)for years, I wish I would have seen this earlier. This is the way
I was struggling for DAYS! Took the brake line of a few times, even took my calliper appart to see if i missed something during the rebuilding. I could not find anything wrong. Then i found your video and it worked instantly. Thanks for sharing this ❤
I tried doing this but still no pressure in my brake handle, at first while doing the small pumps I got some bubbles going for maybe 5 minute but the oil doesn’t seem to lower
Maybe your master cylinder needs a rebuild
Is it normal to still see bubbles after doing this for 45 minutes? I checked all three calipers (ATV), distribution block, and master cylinder and there isn't a leak anywhere (suspecting it was sucking in air somewhere). The handle is firm but bubbles just kept appearing. Going to let it sit overnight and do some more tomorrow.
Man, you saved my life I was pumping that lever all day, I knew something was wrong, but i couldnt imagine it was so easy to fix
same situation
Exactly what I'm exepriencing with a new braided line on '98 Nighthawk. Can't wait to try the subtle pumping approach.
I used my brain and pumped for about 5 min .. but my brain did brain right to tell me to not squeeze all the way haha .. but there were bubbles, maybe not enough. will give it a try tomorrow .. I'm saving this video 😅
German shepperd, THE DOG... Did you know, why seat, with backwards? Because he always protect to us. Best dogs in the world. Literally.
But … how many beards on the beard scale of difficulty (BSD)?? It didn’t work in my case, but it seems if there’s air bubbles near the master cylinder it does the trick. So I’ll keep this one memorized 🤘
Good DIY tip. Learned something new. Thanks. I liked and Subscribed.
Thank you. A combination of back bleeding pushing fluid through the nipple, a couple of gravity bleeds with the clutch pulled and this technique in the video sorted mine
I’m putting a new front master cylinder on my vtx1300c, I’ll have to try this.
Thank you Sir, after a whole afternoon with pumps (and nothing happened) i saw your video and its save me! :)
Omg this video amazing, wow thank you so much Brother you’re amazing and this video saving my time alot to bleeding it 🙏🙏🙏💯💯💯💯
I did this and it didn't work. I might have a leak somewhere. Everything feels tight and i did soapy water to see if i could find the leak and nothing. I actually got them to hold pressure earlier, but I dont know how, but the calipers were on backwards so i had to take them off and flip them and back to square 1. Its a pain.
I was at the point of scrapping my new lines thinking there was an issue and after a day of bleeding and a full bottle of brake fluid I came across your video. Within 2 minutes I felt pressure at the bottom and within 5 minutes it was solid! Thank you so much!
Thanks for posting this video! I just put ape-hangers on my Crossbones (which meant new cables) and had this exact same issue. One important note: It can take a really long time. I was about to give up a couple of times and then I'd see an air bubble pop up. Eventually, I noticed that the lever wasn't going all the way to the grip anymore, so I kept going. In the end, it probably took about 10-15 minutes. If not for this video, I may have eventually taken it to a shop. You probably saved me a fortune here. Edit: Sweet Nighthawk, btw.
Can I do this with the cap on? May screws are stripped
This totally saved the day! Ty! 2000 VN750 wouldn't push fluid to the calipers after a complete overhaul. I followed your instructions, and within 5 minutes we were bleeding the system.
Great idea but not working for me unfortunately. Have a 1977 Kawasaki and just rebuilt the whole front brake system but can't manage to get a firm lever. Brakes work but lever is too soft for my liking.
Mine does not even release the air bubbles... completely confused on this now
This worked like a charm, thank you so much! Might be a silly newb question, but do I still need to bleed at the caliper nipple after this?
Not silly at all, yes, just to make sure there is no air in the caliper and for peace of mind
@@BadAssEngineering Okay cool, I had a feeling. Peace of mind is always the best option. Thanks again!
I'm gonna try this with my electric bike. Just to bleed the rear brake line takes over 2 hours.
Interested in why this works, if anyone can explain it.
Fantastic! Thank you! I did a master cylinder rebuild just before dark and thought I would have to tear it down again. My friend, now I can sleep well tonight
How about a rear brake where the master cylinder is down low, line goes up to an abs unit, then down again to the rear caliper?
what is the purpose of the cover on the two holes at the bottom of reservoir?
It was really the perfect way to remove air! Thanks!
My brake has pressure when pulling the lever fast. But when pulling it slowly there is no pressure. No air bubble coming up at reservoir either.
Any idea what's the problem?
Could be a number of things, old bad fluid, a leak somewhere, a bad master, etc
You beauty, I'm gonna try this now!
Appreciate you bro! Saved me so much time doing other methods
Thank you very much I have the same bike with the same problem. You rock!
Damn bro. You literally saved me. Thanks a lot
Thank you bro that was super useful
This man a hero! I couldn’t figure it out and this gave me the solution I needed! Thanks man!
Should have came here first, Thanks !
so not even gonna use the bleeder valve huh
What if u do this and it's still not building pressure
Worked right away for me thank you so much I really thought I had some other shit going😂
darn..... it didnt work for me
Count me in
Very helpful, I have this issue on my bike but now know how to resolve it :-)
thank you so much your a awesome channel bro 😊😎
Nice Video. Does this also work the same way if bike has ABS?
Depends on how the ABS lines come and go, if they're too horizontal then no
Needs a lot of patience. But it works 👍
Man you are amazing..!
Bro i love you ❤obviously u helped me alot
Very helpfull good video💪💪
life saver mate nothing else was working! thanks
I own you my life 🙏🏻🙏🏻🙏🏻
Not all heroes wear capes
ayyyyy you just saved my day!!!!
And if you want to do it faster, buy a cheap syringe and a tube that fits tightly over the bleeder nipple on the caliper and push liquid through from bottom to top (from caliper to master cylinder).
Worked for me thanks
what about the rear brake!
That 1/8th pull was really effective. Great instruction! Thank you
Hope it works on my clutch
Freakin ABS hub thinger down in the guts of my bike is giving me just the dirtiest of underpants on very random occasions. I'm gonna have to pay someone; there's seven brake lines on this thing and I'm thinking air in the hub. Where else could it be?!?! I've done EVERYTHING!
Yup, this is true.
Wow. Such a simple and elegant solution. I've done my own brakes (on cars/trucks) since the 80's. Did my Goldwing a few times. The brakes weren't worse but also never much better. Always a tad mushy. I'll be doing this method today. Thanks for saving my hands from cramping!
Genius
good job ☺
I'd done plenty of work on car and truck brake systems before but this was my first time doing a full bleed of a motorcycle front brake after opening the system. Pumped my way through half a container of brake fluid before I figured I must be doing something wrong and should look into it more. Found your video and in about 10 minutes had everything bled, back together and on the road. Great video! Thank you!
Dang, I’ve been riden my Atv with soft brake lever for months cuz I thought it needed replaced. Thanks to you my friend, I got a stiff lever again!😂
Dude... you are the first video I have found that explains this way. It does work!!! My polaris atv was a little different in the amount of pull. You also need to let it sit for a few in began trying to get out bubbles. I am assuming this is reverse bleeding. My entire system was replaced and I gravity bleed before doing what this video shows, but it worked like a champ! Thanx bud👊
You are the hero. I never knew I needed. I just replaced the pads and rebuilt the front brakes on my nighthawk 750 and for the life of me I could not build up any pressure thank you my friend.
Hahaha try to do that with Honda Magna double disc brakes. You will be surprised that didin't work. Magnas brake is cursed.......😢
Have you tried removing the calipers from their mounts and letting them hang more vertically v
Yes.... Done that.... Rebuilded calipers with hight quality parts by profesional, lines new. Master cylinder is working good... But still bubbly. I will try your technique tommorow. I think i bought to small master cylinder... Original one messed up so i bought from another bike in good shape. But i think that J.Juan master cylinder was from.single disc brakes so this can cause problem...
3 minutes was a bit optimistic, took me 35 minutes of constant tapping on the lever and brake lines..😅
But it did work, so huge thanks! 😃👍
Without your video I would have given up, and probably ordered a new master sylinder..🤣
3 minutes for me to explain it lol so you don't waste time and can get to fixing stuff 👀
@@BadAssEngineering 💪😁👌
Hi. What about rear break? Is the same rule ? I changed caliper, and pumps all day and nothing:(( please advise 🙏
You could try 👀 depends if the bike has ABS and so on
@@BadAssEngineering no abs. Can i try inject frome bottom by syringe? Thanks
I’m having this issue but with the rear brake/ master cylinder, even with small presses of the rear brake no air comes out, any advice?
Thanks a ton! This worked perfect on my Yamaha YZ250F
hi I cannot thank you enough for your video. I made the same mistake of thinking it would bleed in the same way as a car. The bore of the MC is so narrow that a single bubble would stop it. I was sceptical but I had nothing to loose. It took a good 20 minutes to get all the bubbles out and boom a hard brake. Bled it as normal and its spot on. Thanks again
bassengineering 2024
Every ting i do. But at the end ill bleed the caliper through a little aswell. Just to get rid of any crap thats settled or any air trapped in the caliper. Awsome video. Just watched 1 bloke make a arse of it. Then have the cheek to say it took him 15mins. Yet he had a clock behind him 😂😂😂
King!
Thank you so much, I could not get any pressure and was about to disassemble my master cylinder thinking it was faulty!! 15 minutes after taking your advice my brakes were working perfectly again.
Thank you so much man!
I stripped my front brake system and gave it a clean and could not get pressure when I put it back together.
I did the soft pedal pushes and the bubbles came out as you demonstrated.
Once I had enough pressure in the pedal, I went ahead and bled the front brake and it is good as new.
Worked perfect thanks 👍
I have a race tomorrow but I'm still flying home and will get in late this evening. This was the only thing I needed to resolve on my bike before an early drive tomorrow to the course! Hopefully your tips work and I'll be able to get some rest this evening.
