Product details
This black right MC4 provides a cable-actuated parking brake alongside a separate service-brake system. A sliding caliper, return spring and adjustable lever work over the nominal 0.81-inch-wide rotor. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines. The disc brake company was founded by Bill Wood in 1977 and is based in Camarillo, California.
Technical Details
- Manufacturer part number: 120-12069-BK. Component: MC4 Mechanical caliper.
- Supply: one MC4 parking caliper with its mounting bracket and parking pads; the pads’ exact friction compound should be confirmed if a particular material is required.
- Bore configuration 1.19 inches across 1 piston; piston material: aluminum. The actuation is mechanical, not hydraulic.
- Caliper weight: approximately 3.3 lb.
- Construction and surface: cast aluminum housing finished in Black powder coat.

- Piston dust boots: included.
- Hydraulic connection: none; the caliper is operated by a parking-brake cable.
- Pad fit is type 6407. Match the pad dimensions and compound to the rotor and intended braking conditions.
- Bracket interface: 4.75-inch floating centers with 0.67-inch holes; orientation: right hand.
Fitment & Compatibility
Use the matching 4.75-inch mounting bracket geometry and correct barrel-ended cable. Confirm the mechanism releases fully after adjustment; this caliper has no hydraulic inlet and does not replace a service caliper.
