The Wilwood Combination Parking Brake (CPB) Hydra‑Mechanical caliper pairs hydraulic stopping with a mechanical parking lock to allow disc upgrades and drum‑to‑disc conversions on rear axles that can't accept internal shoes. This right‑hand caliper, in red, uses a 41mm piston and is sized for about .81‑inch rotor thickness; matched to the correct rotor diameter it helps provide balanced rear bias with upgraded front brakes.
