Product details
A red finish and the manufacturer’s Position 1 designation identify this right-rear CPB variant. A single 34 mm piston supplies hydraulic service braking, and an integrated cable mechanism supplies the parking lock. It belongs to the nominal 0.81-inch rotor-width combination-caliper range. 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 exact caliper reference or rear kit parts list to confirm the required Position 1 arrangement. Check cable travel and end fittings alongside the radial bracket and rotor centerline. The stated width and diameter envelope must be respected, but a shared envelope does not prove interchangeability with the standard CPB body.
