Fasst Company Rear Brake Return Spring Kit

7 reviews

Fasst Company Rear Brake Return Spring Kit offers tunable pedal resistance and a better overall feel by placing the spring in compression instead of tension.  The Rear Brake Spring Kit provides a consistent feel, 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.

The kit includes: 

  • Brake return spring & nut.
  • Anodized billet aluminum bucket.


Please Note: This is a 6mm application for a master cylinder with 10mm adjuster or jam nut on the push rod.



  • This is a universal fit part; it may or may not fit without modification.

    Easy Install

    Easy install on a 1290 Super Duke R... much better feel on the rear brake. The only thing missing is the boot/sleeve as others below have stated.

    Rear brake return spring

    The parts are top quality. No instructions are included so you need to have some mechanical ability. The kit adds some needed extra force to apply the brake expesaly wit the addition of the KTM rear sets.

    Works pretty good

    Works pretty good as far as providing a improved feel for the rear brake pedal but like the reviewer below said it needs to have some type of boot to keep the water and dirt out on the 690 Enduro R (which has an issue with the stock brake springs breaking and badly needs this part). I installed it on my 1190 instead and it works great but I would still like to have some kind boot to keep out water and dirt. The one pictured appears to have some type of boot under the spring. I wish I knew what bike that is on so I could see if I could buy just the boot and fit it under the spring.

    Not for a 690, wrong orientation means you should keep the rubber boot instead

    Bought it for my 690, but because of the orientation of the brake actuator (horizontal, not the normal vertical layout) it seems quite foolish to ditch the protective rubber boot... that's fine to do on my XCF-W, so I'll use it there instead, but I would certainly not advise this for a 690 Enduro.
