Simple and easy to follow. Takes the mystery and expense out of bike maintenance.
I can do it
I can learn a new skill
I can save money
I can justify buying more tools

I counted at least 4 steps that no other brake bleed tutorials I've seen on yt have included (doing the 42 degree angle, flicking the brake line, applying brake pressure and doing the quick open/close thing, burping the brake... etc). I definitely prefer this type of tutorial versus the "good enough" kind.

This is by far the best instructional brake bleed video I have ever seen. Bravo guys!!

The serynge holder is the unsung hero of the bleeding procedure.

I swear this channel has the most thorough instructions, everything else is just down to individual technical skill + experience.

I see skilled senior with humble vocabulary and moustache, I susbscribed instantly😎

Lots of people (including myself) miss the point where you put a strap on the lever then open and close the bleed port. This is vital for a firm lever! If you miss this point you'll have a brake with no air but not enough fluid and pressure to give a firm feel.

[swerv]

OMG. I actually did it and it works great. I couldn't believe it. Best video tutorial ever!

[wjeurs]

Love the in depth. Done it so many times now but watch this instruction everytime again

[TheSpectralFX]

These are the best videos I've found so far

[picuszesranej]

You guys are absolutely AMAZING, THE BEST. I LOVE YOU. Im kinda newbie and dumb about bikes and such. Especially whole brake system was kinda hard to understand for me, but i wanted to fix myself. I was reading some articles etc, few videos and it didnt help me at all.But every each one of your videos is so well made, nicely and easy explained.. Only thank to your videos, i got it all now. I fixed everything i needed. Simple, easy and compared to some services very cheap. Thanks so much. Amazing job, good luck fellas.

Best brake bleed video on youtube. I've watched a bunch and this is clear, crisp, to the point, professional, and with some great detail on stuff that other videos skim over. Thank you!!

[Dylan_Draper]

Just followed this process for the rear brake on my Giant Anthem, as it was feeling very spongy, and it worked like a charm! This was very clean compared to other methods I’ve done in the past too!

[andywhitby]

Anyone else caught out by "bring the lever away from the grip as far as it will go"? Turns out my lever fully detaches! And it feels very difficult to reattach.

Yet to resolve, but hopefully I can work out what to do soon.

As with everyone else, otherwise immensely grateful for this and all of your videos!

[tablatom]

Brilliant, thanks for making this process so so clear for a beginner.

[mitchellfreeman]

Big thank you. Mine turned out great. No adjustable bleed nipple because it’s a cheap brand, so I had to skip that step. Still fine.

[Lil_tylenol]

Yeh this was a awesome explanation and by far the best directional video that is done in a very easy to understand tutorial!

[msteiny]

it's a year since this video dropped, and ya'll just save me a $100 visit to the bike shop. Thank you Calvin & Truman for these amazing video how-to's.

[chrisjohnson]

Couldn't ask for a more perfect explanation, thanks!
