Wilwood 120-17144-RD MC4 Mechanical Parking Brake Caliper Left-Hand Red 2" Mount 1.10" Disc

The Wilwood MC4 Mechanical Parking Brake Caliper (120-17144-RD) is a cable-operated, single-piston sliding caliper engineered for applications that require a dedicated, mechanically actuated parking brake. Combining high-output braking performance with a clean, straightforward design, the MC4 is a proven solution for custom builds, street rods, race vehicles, and specialty applications. This is the left-hand, red powder coat version with a 2.00" mounting bracket, designed for rotors up to 1.10" thick and 11.00"–14.00" in diameter.

Key Features:

• Efficient die-cast aluminum body with a forged billet anvil for superior strength under load at a lightweight 3.30 lbs (2.95 lbs without pads)
• 1.19" aluminum piston is fully dust-booted to protect against moisture and debris intrusion
• Lever cartridge clocks in three positions for optimum placement and ease of cable routing
• Accepts a .310" diameter barrel-ended parking brake cable with included cable return spring
• Tool-free manual adjuster allows incremental pad-to-rotor clearance adjustment to compensate for wear
• Includes Composite Metallic (CM) high-friction, high static-hold brake pads pre-fitted with noise-canceling shields
• Floating-style steel mounting bracket with 2.00" center-to-center offset holes (0.67" diameter) for convenient installation
