Wilwood 120-17144 MC4 Mechanical Parking Brake Caliper Left-Hand 2" Mount Type-III Anodized

The Wilwood MC4 Mechanical Parking Brake Caliper (Part No. 120-17144) is a high-performance, cable-operated sliding caliper engineered for applications that require a dedicated, mechanically actuated parking brake. This is the left-hand configuration with a 2.00" center-to-center mounting bracket and a durable Type-III hard-anodized gray finish.

Built around an efficient die-cast aluminum body paired with a forged billet anvil, the MC4 delivers superior clamping strength under load while remaining lightweight at approximately 3.30 lbs with pads (2.95 lbs without). Designed to accept rotors ranging from 0.99" to 1.10" thick with an 11.00" to 14.00" diameter range, this caliper offers broad compatibility across custom and performance brake builds.

Key Features:

• Die-cast aluminum body with forged billet anvil for superior strength-to-weight ratio
• Left-hand orientation; lever cartridge clocks in three positions for flexible cable routing
• 2.00" center-to-center floating-style steel mounting bracket with 0.67" diameter holes included
• Single 1.10" aluminum piston, fully dust-booted to seal out moisture and debris
• Accepts 0.310" diameter barrel-ended parking brake cables
• Includes pre-fitted Composite Metallic (CM) high-friction, high static-hold brake pads with noise-canceling shields
• Factory-installed cable return spring for consistent, reliable engagement
• Tool-free manual adjuster for incremental pad-to-rotor wear compensation
• Engineered noise-dampening features for quiet, rattle-free operation
• Type-III hard-anodized gray finish — corrosion-resistant and built for long-term durability
• Features Wilwood's signature logo

The MC4 is the ideal solution for performance street builds, kit cars, and custom vehicles that require a separate mechanically actuated parking brake caliper. Sold individually.
