Description
The Wilwood PS-1 Right Brake Caliper (part number 120-8373) is a hydraulic brake caliper configured for the rotor and mounting dimensions listed below. It uses lug mounting with a listed nominal rotor thickness of 0.19 in.
Piston sizing, rotor thickness, and mounting geometry determine how this caliper integrates with the brake system. A matching pad shape identifies the pad interface, while compound selection remains a separate operating-temperature decision.
