Product details
The clear-anodized right Wilwood HE1 is an individual hydraulic and electric parking caliper. It combines a 4.75-inch attachment span with 1.25-inch piston bore; confirm the rotor centerline and 0.39-inch width configuration before installation. 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. The HE1 Hydra-Electric sliding caliper combines hydraulic actuation with an electric parking mechanism. Its single hydraulic piston, 1/8-27 NPT inlet and motor distinguish it from an electric-only EPB caliper. Both the hydraulic circuit and separate parking controls must be configured for the vehicle.
