Product details
A 1.10-inch rotor-width specification and 1.25-inch piston bore identify this left Wilwood EPB electric parking brake caliper. The polished finish is applied to the exact component described below; match the mounting bracket before replacement. An electric motor and reduction drive operate this separate parking caliper. The brake-system controller, harness and dashboard switch are separate components. Mounting geometry, motor clearance and rotor width must all be checked; this is one caliper rather than a complete parking-brake conversion. Based in Camarillo, California, Wilwood Engineering has its origins in the company Bill Wood founded in 1977. Its designs and manufactured disc brake products cover calipers and rotors alongside master cylinders, valves, fittings and lines. Motorsport, street-performance and specialized installations each require components selected for the complete system.

One electric parking caliper with its motor; the control module, harness, dashboard switch, rotor and vehicle-specific mounting adapters are separate. Confirm the required pad configuration before assembly.
Fitment & Compatibility
Use this motor-operated caliper only as a parking brake in a properly engineered installation. Confirm the motor side, rotor centering and mounting plate. The controller, electrical harness, switch and vehicle-specific attachment hardware must be selected separately; no hydraulic inlet is used.
