Description

The Chase Bays Dual Piston Brake Booster Delete with Bolt-On 6:1 Pedal Ratio is an all-inclusive conversion kit designed to provide consistent and controllable braking for motorsport applications. This kit replaces the factory brake booster and includes a 1-inch bore ultra-compact master cylinder, an isolated front/rear circuit fluid reservoir, and a billet firewall adapter plate.

It features a stainless steel bolt-on adapter that changes the pedal ratio to 6:1, offering increased leverage for the master cylinder and enabling the use of a larger master cylinder for better braking feel and more force to the calipers with less leg effort. The system is approved for various sanctioning bodies like FIA, Formula Drift, SCCA, and WRC.
