Finding the tunability of rear brakes.
Our Rear Brake Return Spring offers tunable pedal resistance and a more controllable feel by placing the spring in compression instead of tension, minimizing the "on-off" feel of most rear brakes.
The pedal resistance can be adjusted by how much preload is placed on the spring. The Return Spring Kit also minimizes debris from jamming the master cylinder as well as eliminating the stock tension return spring that attaches to the pedal.
Rear Brake Pedal Return Spring Kit consists of spring, spring bucket and nut. The Spring Bucket contains the spring as well as seals the master cylinder with the stock rubber dust boot.

Replaced the factory clevis and spring with fasst setup. Super happy with the quality and function and it looks awesome as well. Pedal feel is great! I love that I won’t have to use the clutch cover spring anymore.
J
The spring in conjuction with the clevis improved my rear brake feel tremendously. The improvement was so nice it took no time to adjust and my on trail confidence improved immediately.

I made my first ordee from fasst co. I made a stupid easy mistake ordered the wrong part. It was 100 percent my fault by the time I relized I made the mistake the part was already shipped but John from fasst co was excellent to talk to on the phone and was completely understanding to the situation got the correct part shipped and upon the return of the incorrect part I will be refunded the money for the part I ordered incorrectly. It was an extremely plesent experience and would definitely recommend fasst com to anyone who might need something they sell.
