Brake Caliper, Seals & Temperature

Because race brake calipers are sometimes subjected to very high and unpredictable operating temperatures, they must be examined and seals must be replaced on a regular basis to maintain efficiency and safety. Seal life is governed by time at temperature which should therefore be kept as low as possible by provision of cooling airflow. For guidance only AP Racing offer the following recommendations (temperatures measured on outside of caliper adjacent to logo): - Calipers that regularly run at up to 200°C - Re-seal every other event. - Calipers that run intermittently from 200°C to 220°C abd above - Re-seal as soon as possible. - Reduce "soak" temperatures after the car has come to rest where possible (e.g. do not leave foot on brake pedal when stationary with hot brakes) as this can cause excessive caliper temperatures.

Kit includes:

2 x 1.250" high temperature piston seals

2 x 1.42"(36mm) high temperature piston seals
