TECH TIP: Bleed Bicycle Disc Brakes Right the First Time Like a Pro!

In this video we show you how bleed bicycle hydraulic disc brakes like a pro. The trick to bleeding hydraulic disc brakes is to understand the fundamentals first. In this video we show you the tricks and techniques the pros use to get the job done without fail or fuss.

Love how you demonstrate the importance of the right direction for the calipers in the beginning, and THANK YOU for showing how to bleed a rear brake, instead of just taking the easy way out on the front brake like most others 🙂 Great job!

[GerhardGeficky-jgok]

Finally someone who knows what they are talking about about. Everybody misses this step on YouTube. Thank you Sir

The most comprehensive video on YouTube on how to bleed brakes correctly. I have watched so many videos and could not figure out how to get the air bubbles out of my rear DI2 brakes until now. Thank you so much!

Best and most simple explanation so far on YT. Thank you !

There will also be air in the master cylinder (shifter body). Loosen the handlebar and rotate the bar up and down while pumping the lever to get more air out. Same concept as you demonstrated in the beginning.

after 5+ years, I almost gave up on brake bleed until @1:17. I don't think anyone on this planet has shown this critical point.

Excellent demo. I built something similar to demonstrate to customers how these units function. I also did an indexing unit to show how that works. I used Shimano Deore but the principles are all the same.

All the video's are far the best on Youtube. Thanks for your help !

Great explanation. A lot of mechanics should see this video.

This is one of the best explanations of what goes on in a brake system. Have you ever played with a vacuum bleed on mtb or road brakes? This will be my next project to improve the quality of bleeds in our shop. Thanks for making this.

Omg this video explained my issue in a nutshell 😮, not tilting calliper at correct angle and using DIY bleed spacer made of cardboard which didn’t push pistons back fully

[HenryReinosa-te]

I’ve only seen videos on how to bleed the front brake, I’m glad I came across this video!

[JamesEllisPT]

This is the video I wish I’d watched 3 months ago! Every time I was doing a bleed I was having air in the caliper. Taking it off was the only way to get it cleared, and rotating the bike in the stand didn’t work. Thanks

Bu bilgi altın değerindedir gösterdiğin örnekteki gibi mantık aynıdır işe yarıyor.

[yuvalon]

Great demonstration, especially the beginning, to see the principal in action. Question - would that work also with a syringe connected at the pump, instead of a cup? In some videos it seems like we need to bleed both the caliper and the pump, while in others (like in this video), it seems like bleeding only the caliper is enough?

[NicolasCristi-in]

Thank u so much, this sucking air because of opening the nipple too much is exactly what has been happening in my bleedings, is what I feared.

Planning on replacing the mineral oil in my brakes. Would you recommend a gravity bleed first to flush out the old oil, then do the caliper oil injection to bleed the air up towards the lever? My concern is that the old oil might have sediments which a gravity bleed is best to address.

Great video! Love how you almost yell at us, knowing we have done wrong before.. 😄 #rehearsalwins

Hi.
I'm using the file oil what can I do thanks ❤

The first time I've ever heard anyone mention anything about aeration.

I have tried to avoid aeration but no one ever mentions it.
