@ 3:24 ...I have been a mechanic/bike racer/bike nerd for years and never thought of this one. That is an awesome tip and will use it. Thanks for a great video.

As someone who is building their first bike, this is a life saver. Thank you!

[danharrisdesign]

Simply the best "how to" on brake installation/bleeding! Thank you!

[ilyapo]

I wish every tutorial would be like this one - stylish and clear

[trialmx]

I discovered you recently and have been binge watching your videos. They really resonant with me as a recreational rider and mechanic. You've talked of naps on occasion during a ride, when I go out on a hike I usually get a nap in along the way in a hammock. I may adapt naps to my rides. Enjoyed the jazz!

Thank you so much for this video.  Not enough "top to bottom" videos on YouTube (yours was the only one I could find) for this procedure.  Very clear, very thorough.  I'm building my first disc bike now, and I'll probably be installing the brakes in a few days after my wheels arrive.  After watching your video I feel much more confident to tackle the job.

Mate your videos are so complete and clear. Invaluable. Thanks!

[khazza]

I've just gone through ~15 vids on disc brakes setup... this one by far the best!

Thank you so much!

Dude! I still come to this video when I need to bleed my own brakes. This is what I call evergreen content lol. Thanks bud.

Related to hydraulic brake, this is the best video I've ever seen!

[SirFartsAlot]

All other videos only do the first part and I would wonder why my lever wouldn't get any firmer, thanks to you now it's great thank you so much!

[eliotroberts]

About to do the transition from RS785 to R9170, this video is super helpful, love your content. Many thanks!

[Xiusepe]

Helped by this video on 2022! And that jazzy background music…always with class.

[markbrown]

The most beautiful “how to” video I’ve ever watched!

[arthurmcneal]

I will bet bike shop mechanics are making a fortune installing and maintaining these braking systems.I for one will stick with my standard sidepull caliper brakes.I applaud the guy who did this video though.

[U.s.e.r.]

Came across your build series....about to start my own little build. Following all your guidance! 👍👍

[nikveldkamp]

Excellent video! Well shot and edited. More importantly, I could manage my shift from mechanical to hydraulic for the first time without any flaws. Thanks for the help!

[haidau]

Great job on this very thorough beginning to end installation, bravo!

[richardm]

Thanks for this video! Watching it now in July 2020. Very useful and helpful as I am bleeding brakes for the first time and am having trouble because air has obviously got trapped in the cable. I will go and try again!

[durtsurferr]

You were the only vid I could find for a dry bleed. Thanks! If you have GRX I’d love to see that specifically
