Product Description

The Wilwood 120-15485-BK MC4 Mechanical Parking Brake Caliper is designed to provide reliable cable-operated parking brake functionality for custom brake systems and motorsports applications. Featuring a compact forged aluminum body, this left-hand mechanical caliper integrates a strong internal mechanism that converts cable pull into clamping force on the rotor. The design allows it to function as a dedicated parking brake caliper when paired with separate hydraulic service brake calipers.

Equipped with a 1.19-inch piston and engineered for rotors approximately 1.10 inches thick, the MC4 caliper provides dependable holding power for parked vehicles while maintaining compact packaging for custom rear brake assemblies. The durable black powder coat finish offers corrosion resistance and a clean performance appearance. This caliper is commonly used in hot rods, race cars, drift builds, off-road vehicles, and custom brake conversions where a mechanical parking brake is required alongside high-performance hydraulic braking systems.

Because the MC4 caliper is designed for universal applications, installation requires proper mounting brackets and compatible brake cables. Always verify rotor thickness, mounting configuration, and cable routing before installation.
