- 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

After 30 minutes of pumping and nothing happens I’m like I did something wrong in my installation but let me CZcams it first and you basically save my day thank you so very much
Man… that LITTLE detail, of not “squeezing” the lever… Gold!
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.
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.
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
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.
Finally a video showing the fix for no pressure at the lever after fluid replacement. Thanks
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 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.
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!
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!
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.
Thought I wasn't going to accomplish my goal of riding to work Monday. This SAVED me.
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
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.
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.
Like many of the other folks commenting, I’d been pumping and pumping the brake lever and even had to get another bottle of brake fluid. 60 seconds of the light pressure on the lever and it was good as new.
Thanks for saving me a trip to the shop!
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 ❤
Thanks flushed my break fluid for the first time. You are a life saver.
Dude this helped so much, it never goes like this and for once I had to do it different. I was going through every problem possible but yours was the only fix. Much appreciated
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
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.
Exactly what I'm exepriencing with a new braided line on '98 Nighthawk. Can't wait to try the subtle pumping approach.
This man a hero! I couldn’t figure it out and this gave me the solution I needed! Thanks man!
I spent riddiculous amount of time trying to stiffen the lever using common method until i saw your vid. Thank you so much for this
You saved the day. Thank You Very much. I have bled cars many times so I figured scooters where the same. I let the reservoir get too low and air must have gotten in the line. So every time I pumped the handle I could not bleed the system. No fluid drain at the bleed valve and no pressure on the handle. I saw your post last night and could wait to try it this morning. Sure enough, exactly like you said. A few small pumps and I could see the bubbles and the handle started to stiffen. Several more and Voila. It was done. Thanks again.
Dude I was about to go to a shop then I tried this out. And it worked! I've been trying to bleed this for days and it took me a few minutes. Thank you so much dude!
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!
Have used this technique working on dirt bikes for years. Found out by accident;,the small actuations are the key👊👊
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.
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👊
This video saved me so much money! Thank you so much, could not understand what was going on and this video was spot on.
This worked and saved me a ton of headache! THANK YOU!
those tiny bubbles made all the difference. totally squishy to stiffer than heck. thank you boss
Good video for bleeding the front brakes on a bike... explained nice and easy and good quality vids shows it all, well done.
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.
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 video saved my brakes rebuild, thank you so much for making this!
Changed my caliper to Brembo radial and been pumping all day, your video and tips saves me. Big thanks!!!
Idk how much you know how much you helped me out. But Thank you!
Just tried this and it worked like a charm.
Thank you sir. New line and never bled the brakes. Pumped the 1/8 turn until is was good to go and only took a few minutes
That 1/8th pull was really effective. Great instruction! Thank you
Hope it works on my clutch
life saver mate nothing else was working! 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.
You just blessed me bro, this worked first try
You are my HERO, can you please do more motorcycle videos !!
Thank you very much I have the same bike with the same problem. You rock!
Very helpful, I have this issue on my bike but now know how to resolve it :-)
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!😂
Definitley not 3 mins, but it worked like a charm. My only lessons learned, if you're not getting bubbles, adjust the pressure on the pull, then go back to the light pull. It took me about 30 mins of modulating on new brake lines to get about 90% pressure back. Then I attached a bungie cord from the lever to the grip, to apply just enough pressure to keep the valve open. In the morning after removing the bungie, pressure was 100%.
Thank you for the help the other methods didn't work and this methods worked vary fast
Appreciate you bro! Saved me so much time doing other methods
Thank you,thank you, struggled for 4 days ,trying to get front bled. Went out to the garage ,15,minutes later it was all set to take a ride
Thanks a ton! This worked perfect on my Yamaha YZ250F
came back to this video after it solved my first time working on my brakes when I went to replace my cables I also had to bleed my master cylinder could be an easy thing to miss as well for anyone having issues even after this video.
oh ur a legend just saved me for race weekend
For a total dry to wet bleed sometimes the caliper itself naturally traps air due to the shape and a reverse bleed may be necessary using a syringe from the bottom up
I am going to try it and definitely follow up.
Worked perfect thanks 👍
Thanks bud, worked a treat!
Omg this video amazing, wow thank you so much Brother you’re amazing and this video saving my time alot to bleeding it 🙏🙏🙏💯💯💯💯
Damn bro. You literally saved me. Thanks a lot
Worked right away for me thank you so much I really thought I had some other shit going😂
Many Thanks for this video!! Been chasing my Tail with this
Bad Ass indeed !!!! Have been dickin around for months and you solved it ! Yur a MONSTER ... Thank You !
Excellent tip... thanks
Thank you, just got it done
very good video, will be trying that tomorrow morning.....also nice honda you have
Great video. Appreciate it.
Most effective and time saving bleed...❤
Thankyou Sir, worked a treat!
Awesome!! Could not figure out why no pressure, I thought I bled them enough. Turning the bars and getting the line as even as possible did the so much more air bubbie were in there
*trick
Will give it a try. Thanks.
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!
Thnx, worked out perfectly...
Thank You for the video!
From a dry line, how long/how much fluid should this take?
Thank you very much my friend, totally worked for me. My front brake jammed up while I was riding and the lever was stuck and was unable to move my front wheel after pulling to the side of the road. Finally it loosed-up and I rode home without using my front brakes. I was hoping not to rebuild my master pump so decided to just change the brake oil and clean the piston. Afetr flushing out the old brake fluid and using WD40 to lubricate and clean the piston, it was moving freely. Top up new brake fluid and starting pumping the lever but never got stiff, so decide to bleed the brake fluid and started to pump the lever again. I saw some air bubbles being released in the resevoir but the lever never got sfiff. I started thinking the O ring or the rubber on the piston could have been worn out. That was when I decided to take a break and search in youtube. After a few videos, sported your, and made sense about the air getting trapped around the master cilender area. Decided to give it a few tapping with my palm and pumping the lever as you described, I could see more air being released, a few more tapping and pumping and the liver finally became stiff. The brakes are working fine now and the lever fully retracts back to press on the brake switch, early there was a gap and the brake lights would stay ON. Thank you my friend, your video truly helped me...😜
Hi mate! Be careful using WD40 on your pistons, it’s a water displaced and shouldn’t be used for lubrication. I think copper grease or another grease would work better and be safer
Helped out alot, thanks👌👌
Brilliant, thanks heaps for this. Worked a treat on my VFR
Thanks for the video, but how about the rear brake. Not working so well for me on the rear brake.
Amazing. Thanks so much!
Keep getting air in my clutch line. I’ll give this a go 🍻
Should have came here first, Thanks !
Bro i love you ❤obviously u helped me alot
I do this same thing and build a tiny bit of pressure and it just won’t build any more after that. How do I fix this?
Great video, I'm currently having this issue right now with my brakes as I just replaced my lines with stainless steel cables too. Question - do you have your bleeder nipple cracked open while doing this?
No, closed
Thank you !
Worked for me thanks
gracias
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!
Thank you
Thanks so much
Man you are amazing..!
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?
Saved my life
I lOve you damn ashole😂😂😂 you help me i try 12 days to make it until i see your clip damn you are king
Very helpfull good video💪💪
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?
