Description
The Wilwood Powerlite ST Brake Caliper (part number 120-15734) is a hydraulic brake caliper configured for the rotor and mounting dimensions listed below. It uses radial mounting with a listed nominal rotor thickness of 0.50 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.
