Wilwood 120-17143-RD MC4 Mechanical Parking Brake Caliper Right-Hand Red 2.00in Bracket

The Wilwood MC4 Mechanical Parking Brake Caliper (Part No. 120-17143-RD) is a high-performance, cable-operated sliding caliper engineered specifically for applications that require a dedicated, mechanically actuated parking brake. This right-hand unit ships in Wilwood's signature high-gloss red, high-temp, brake-fluid-resistant powder coat finish.

Built around an efficient die-cast aluminum body paired with a forged billet anvil, the MC4 delivers exceptional strength under load while keeping overall weight to just 3.30 lbs. with pads (2.95 lbs. without). The caliper is designed to accept rotors ranging from 0.310" to 1.10" thick across an 11.00"–14.00" diameter range, making it adaptable to a wide variety of custom and performance brake setups.

Key Features:

• Floating/sliding caliper design with a 2.00" center-to-center steel mounting bracket included
• 1.19" single aluminum piston fully dust-booted to seal out moisture and debris
• Lever cartridge clocks in three positions for flexible cable routing and optimum lever placement
• Accepts a 0.310" diameter barrel-ended parking brake cable; cable return spring included
• Tool-free manual adjuster allows incremental pad-to-rotor clearance adjustment as pads wear
• Supplied with Composite Metallic (CM) high-friction, high static-hold brake pads pre-fitted with noise-canceling shields
• Noise-dampening construction for quiet, rattle-free operation
• Available in right-hand (120-17143-RD) and left-hand (120-17144-RD) configurations
• High-gloss red powder coat is high-temp and brake-fluid resistant; also available in black
• Features Wilwood's signature logo

The MC4 is sold individually and is an ideal choice for custom builds, restomod projects, and any performance application where a separate mechanical parking brake caliper is required alongside a primary hydraulic brake system.
