Wilwood 120-17143-BK MC4 Mechanical Parking Brake Caliper Black Right-Hand 2.00" Mount

The Wilwood MC4 Mechanical Parking Brake Caliper (120-17143-BK) is a high-performance, cable-operated sliding caliper engineered for applications that require a dedicated, mechanically actuated parking brake. Finished in a black high-gloss, high-temp, brake fluid resistant powder coat and featuring Wilwood's signature logo, this right-hand caliper delivers reliable stopping power with a clean, professional appearance.

Built around an efficient die-cast body paired with a forged billet anvil, the MC4 provides superior strength under load while keeping overall weight to just 3.30 lbs (2.95 lbs without pads). It is designed to accept rotors from 0.310" to 1.10" thick across an 11.00"–14.00" diameter range, making it a versatile choice for custom brake setups.

Key Features:

• Sliding caliper design with a 2.00" center-to-center mounting bracket (0.67" diameter holes) for straightforward installation
• 1.19" fully dust-booted aluminum piston keeps moisture and debris out for long-term reliability
• Lever cartridge clocks in three positions for optimum placement and ease of cable routing
• Accepts a 0.310" diameter barrel-ended parking brake cable with included cable return spring
• Tool-free manual adjuster allows incremental pad and rotor wear compensation without special equipment
• Includes Composite Metallic (CM) high-friction, high static-hold brake pads pre-fitted with noise-canceling shields
• Noise-dampening engineering for quiet, rattle-free operation
• Includes a steel mounting bracket for convenient installation
• Available in both right-hand and left-hand configurations (sold individually)

The MC4 combines high-output parking brake performance with a straightforward mechanical design, making it an ideal solution for street rods, race cars, kit cars, and custom builds that require a separate parking brake caliper independent of the primary hydraulic system.
