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 from 0.81" to 1.10” 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 or red high-gloss in a high-temp, brake fluid resistant powder coat and feature Wilwood’s signature logo.
About Wilwood Engineering
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since the company’s inception in 1977 by Bill Wood, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Our core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
With headquarters in Camarillo, California, Wilwood employs approximately 250 people. We have on-shelf stock of more than 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Our off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment, to heavy duty original equipment brakes for the U.S. military Humvee.
Wilwood's engineering department uses the latest computer-aided design and manufacturing techniques in conjunction with finite element analysis, dynamic test and cycle test equipment, to find high-performance and reliability solutions for the most difficult braking tasks. Our extensive inventory of proprietary on-the-shelf components allow us to provide cost-effective solutions for unique brake applications.
Wilwood is ISO 9000 compliant and has extensive experience maintaining quality levels of 100ppm or less for original equipment manufacturers.
