Wilwood Left Hi-Torque EPB Red Parking Caliper with 4.75-Inch Bracket Centers

This red left-hand EPB supplies the Hi-Torque motor option in the 0.81-inch-width parking-caliper format. Its electric drive applies the brake through a single mechanical piston, leaving service braking to the vehicle’s hydraulic system. The caliper is supplied as a component, so the mounting and electrical installation must be planned around it. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility

Use the 0.75–0.81-inch rotor thickness range to select this version and confirm the actual rotor diameter and pad track. Check the 4.75-inch bracket centers along with offset, motor position and wheel-spoke space. The operating switch, harness and compatible control module must agree with the exact motor specification.
