This kit includes the following to rebuild one pair of calipers:
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.
- 4 Pressure Seals (36mm)
- 4 Dust Boots (36mm)
- 4 Stainless Steel Pistons (36x30mm vs. OE 36x29mm)
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.
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.
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.
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
