CYCOBYCO Bicycle Brake DOT Oil Bleed Kit: A Comprehensive Set for AVID, Sram, Formula, Hayes, Bngal, and More! Review

Hayes Stroker Trail caliper does not have a bleed adapter making the whole kit useless to me. The description says "Hayes all series".

Bought these brakes for my Formula C1 brakes. The shoulder diameter on a fitting was too large and would not tighten properly to seal. Difficult to pull the vacuum the way you want unless it's attached to the brake.

Very unsatisfied. Contrary to other information, they do NOT work with 2017 Sram Guide RS brakes. Very disappointed, should have bought the original. The brake caliper bleed screw does not have a suitable mount.

Was just what I needed to bleed the brakes on my Haynes PRIME Expert brake system. The instructions could use some work. FYI, don't over tighten the connections, I broke one of my syringes this way.

I have used this to bleed Guide RS brakes. The tubing and syringes were a little flimsy but never let air into the system. The instructions were helpful and I was able to bleed the brakes. I would recommend buying more gloves as only one pair is included.

Bleeding the Avid Juicy 7 brakes required many steps, but none of them were that difficult. I watched a few youtube videos on how I did it and the bleeding went well. This kit was inexpensive and worked well. Much cheaper than taking them to a local store and they are booked for a month.

This worked with a few modifications to my Hayes 9, it didn't come with everything shown in the picture I ordered it from but it did come with its zip closure, to limit the depth with the bleeding needle I could bleed my master. It only lasted a few minutes after fumbling around for about 3 hours without pumping. Worked great, but I hate people who falsely advertise
