Product Description

The Wilwood 120-12069-BK MC4 mechanical parking brake caliper is engineered for applications requiring a dedicated, cable-operated parking brake solution. Designed as a standalone unit, it provides strong and reliable holding force, making it ideal for performance vehicles, custom builds, off-road rigs, and race cars that utilize separate hydraulic braking systems. Its compact sliding design allows for flexible mounting across a wide range of custom brake setups.

Constructed from a lightweight die-cast aluminum body paired with a forged billet anvil, the MC4 caliper delivers excellent strength and durability without adding unnecessary weight. The integrated 1.19-inch piston is fully dust-booted for long-term reliability, while the adjustable lever mechanism allows for multiple cable routing positions. Pre-equipped with high-friction composite metallic pads and noise-dampening hardware, this caliper ensures consistent, quiet operation and dependable parking brake performance in demanding environments.
