CP8350 Competition Brake Caliper

The AP Racing CP8350 Competition Brake Kit, part number 13.01.10000, is a front brake system designed by Essex and AP Racing specifically for track use. The calipers are constructed from anodized aluminum with machined stainless steel pistons and include anti-knockback (AKB) springs. These springs help to mitigate pedal "pucker-factor" moments by tensioning the pistons, ensuring they return to a neutral position and reduce brake drag. The caliper design prioritizes durability under extreme heat. Unlike OEM dust boots that can quickly degrade on the track, these calipers utilize high-temperature piston seals, similar to those found in NASCAR and ALMS. This design choice, while omitting dust boots, leads to less frequent maintenance and servicing under track conditions. Installation and maintenance are simplified with features like a single-bolt pad change mechanism, allowing for quick pad swaps using basic tools. The bleed screws and crossover tubes are integrated into protective coves within the caliper body, shielding them from impacts with wheels or track debris. This design also contributes to the caliper's ultra-lightweight and compact profile, aiding wheel fitment and reducing unsprung weight. Piston sizes are specifically chosen to work seamlessly with the OEM master cylinder and ABS system, allowing integration with stock rear brakes without adverse effects. Essex Parts also offers a lifetime professional reconditioning service for these AP Racing calipers, ensuring they can be maintained and restored to peak performance for continued track use.
