120-12070-BK - Product Description

MC4 Mechanical

Wilwood’s MC4 Mechanical Parking Brake Caliper is a multi-use, cable operated brake caliper that combines high output performance with simplicity in design and construction, and is the perfect solution for vehicle applications requiring a separate, mechanically actuated parking brake caliper. Built to accept rotors that are .810” thick, with 11.00” - 12.88” diameter range, the MC4 combines an efficient die cast body with a forged billet anvil for superior strength under load, yet is lightweight at only 3.30 (2.95 without pads) pounds. Supplied with each caliper are our Composite Metallic (CM) high-friction, high static-hold brake pads, and are pre-fitted with noise cancelling shields.

Engineered with noise-dampening features for quiet, rattle-free operation, the MC4 sliding caliper includes a steel bracket for convenient mounting. Available in both right-hand and left-hand construction, the caliper’s lever cartridge can be clocked in three positions for optimum positioning and ease of cable routing. The 1.19” aluminum piston is fully dust booted to keep moisture and debris out. Each caliper is fitted with a cable return spring, and the mechanical lever accepts a .310” diameter barrel-ended parking brake cable*. The convenient manual adjuster requires no special tools, allowing incremental adjustment to compensate for pad and rotor wear. MC4 calipers are available with either black, silver or red high-gloss, high-temp, brake fluid resistant powder coat and feature Wilwood’s signature logo.
