Description
 

This kit includes the following to rebuild one pair of calipers:

  • 4 Pressure Seals (36mm)
  • 4 Dust Boots (36mm)
  • 4 Stainless Steel Pistons (36x30mm vs. OE 36x29mm)
Dust boots in this kit are made of EPDM (Black) which is the standard material as OE and has a temperature range of up to 300F.

A higher temperature (450F) boots (Blue) made of Silicon can be chosen for tracking purpose (per option above), however extreme caution must be exercised to avoid those high temp boots in contact with brake fluid, or pre-mature rupture (see pic below) will occur due to the material in-compatibility.

Notice that these RacingBrake caliper rebuild components do not include and do not need shims. Eliminating the need for shims lowers overall cost and more importantly allows more direct positive torque transmission resulting in better braking.

These stainless steel pistons are excellent upgrade for your stock aluminum pistons, not only they are stronger and more rigid than aluminum, they will not corrode and can transmit more brake torque but with less heat (about 1/10) than stock aluminum pistons.

Our pistons also have vents to further prevent heat transfer to fluid, allow you to run your brake system at lower temperature which means less replacement on brake fluid, and eliminate the use of titanium shims saving you down time, operating and maintenance cost.

If you are hard on brake and have been looking to improve your overall braking efficiency, and tired of replacing brake fluid and don't like the soft pedal due to the use of heat shield Titanium shims, look no more!
