Wilwood 120-15485-RD MC4 Mechanical Parking Brake Caliper Red Left-Hand 1.19" Piston

The Wilwood MC4 Mechanical Parking Brake Caliper (Part No. 120-15485-RD) is a versatile, cable-operated parking brake caliper engineered to deliver high-output braking performance with a straightforward, reliable design. It is the ideal solution for builds requiring a dedicated, mechanically actuated parking brake separate from the primary hydraulic system.

Key Features:

• Die-cast body with forged billet anvil — delivers superior strength under load while keeping weight to just 3.30 lbs. (2.95 lbs. without pads)
• Left-hand construction — designed for proper driver-side installation; right-hand version also available
• Three-position lever cartridge clocking — allows optimum caliper positioning and simplified cable routing
• 1.19" aluminum piston — fully dust-booted to protect against moisture and debris intrusion
• Accepts rotors 0.310" to 1.10" thick with an 11.00"–14.00" diameter range; 4.75" floating mount bracket included
• Composite Metallic (CM) brake pads included — high-friction, high static-hold compound pre-fitted with noise-canceling shields
• Cable return spring included — mechanical lever accepts a 0.310" diameter barrel-ended parking brake cable
• Tool-free manual adjuster — incremental pad and rotor wear compensation without special tools
• Red high-gloss powder coat finish — high-temp, brake fluid resistant coating featuring Wilwood's signature logo

The MC4 sliding caliper includes a steel mounting bracket and is engineered with noise-dampening features for quiet, rattle-free operation. Whether used in a performance street build, custom fabrication, or race application, the MC4 provides a clean and dependable mechanical parking brake solution.
