Really easy to use

First time I've bleed a set of brakes but this kit made the task really easy.

Seemed easy enough

I have never bled brakes before but needed to be back on my bike quicker than the wait time for the shop to do them, hence the DIY option.

I bled my brakes, which was very easy following the printed instructions and using the kit. Everything I needed was in the kit.

I'm back on my bike as I wanted to be.

Great, simple and quick to use bleed - kit.

First, excused my bad English - it's not my first language and I'm an old German ;) ...

I brought this kit because my Hayes Dyno Sport brakes needed a bleed after the change of an master cylinder. Then I looked at the internet what I need to do this ...

I found this fabulous page with great success for all brakes you can name.

Okay - so I did and the kit arrived a week after the order.

The instructions are a little different than the original from Hayes, but it works perfectly, fast and clean *thumbsup*.

The build quality is very good and after use you should clean all parts of the kit - and the brake - with dishwater - then it will last a lifetime.

I highly recommend this kit every bicycle enthusiast as well as the shop.

Great kit, fabulous service and last but not least a very good price. Get it and your Hayes Dyno brake breaks like mine = Better than new.
