Wilwood 120-10112-13-BK CPB Hydra-Mechanical Combination Parking Brake Caliper – Driver Side, Black, 41mm Piston, .81" Disc

The Wilwood 120-10112-13-BK Combination Parking Brake (CPB) Hydra-Mechanical Caliper delivers a dual-function braking solution — using hydraulic pressure for normal service stopping and an integrated mechanical locking mechanism for parking brake engagement. Designed for rear axle disc brake conversions and upgrades where traditional internal shoe systems are not practical, this caliper opens up new installation possibilities for custom and performance builds.

Single-Piston Floating Design with Radial Mount:

• Single-piston floating design attaches to a fixed radial mount bracket for precise, self-centering alignment
• Floating mount maintains correct caliper position when the cable-actuated parking brake lock is engaged and released
• Prevents excessive pad knock-back on C-clip rear axles with measurable side play
• As pads wear, the caliper automatically remains centered over the rotor
• Radial mounting offers nearly unlimited bracket positioning options — adjustable for height and lateral offset relative to the hat and rotor

• Aftermarket hand brake kit suppliers can easily configure a compatible cable end for custom installations

Constructed from lightweight aluminum with a durable black powdercoat finish and Wilwood logo, this CPB caliper is an ideal solution for drum-to-disc brake conversions, rear disc upgrades, and performance builds requiring a clean, integrated parking brake function.
