Product details
The black left-hand Position 1 CPB is a rear combination caliper with a 34 mm hydraulic piston and cable-actuated parking mechanism. It uses the nominal 0.81-inch rotor opening in the floating radial-mount arrangement. Position 1 is a specific factory variant that should be matched to the brake package by exact reference. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.

Fitment & Compatibility
Confirm the Position 1 requirement before substituting for another left-hand CPB. Check the rotor centerline, 5.98-inch radial bracket, cable approach and M10 x 1.00 inlet against the application drawing. The available documentation does not establish a clocking angle for the designation, so that detail should be verified directly when selecting the caliper.
