Wilwood 140-14591-DR CPB Rear Disc Brake Kit 12.19" Drilled Rotor Red Caliper

The Wilwood 140-14591-DR CPB Rear Disc Brake Kit delivers a fully integrated hydraulic and mechanical braking solution for vehicles requiring a dedicated rear disc parking brake. The kit features Wilwood's Combination Parking Brake (CPB) calipers, which utilize hydraulic pressure from the master cylinder for normal service braking while an internal mechanical locking mechanism within the caliper provides secure parking brake engagement — eliminating the need for a separate drum-in-hat assembly.

CPB kits are engineered primarily for front-wheel drive vehicles and select rear-wheel drive axle configurations that are not well suited for internal shoe-style parking brake systems. The result is a clean, high-performance solution that delivers consistent, balanced braking performance at the rear axle.

Key Features:

• 12.19" drilled two-piece rotor with lightweight aluminum hat for improved heat dissipation and reduced unsprung weight
• Combination Parking Brake (CPB) calipers in red finish — hydraulic service braking with integrated mechanical parking brake lock
• BP-10 high-friction compound brake pads for strong, fade-resistant stopping power
• Drilled rotor surface for improved wet-weather braking performance and thermal venting
• Designed to complement Wilwood front big brake upgrade kits for balanced front-to-rear brake bias
• Ideal for front-wheel drive platforms and select rear-wheel drive axles incompatible with drum-in-hat parking brakes

The Wilwood CPB Rear Kit is the ideal upgrade for performance street builds, track cars, and custom vehicles where a conventional drum parking brake is not an option. The oversized rotor, aggressive pad compound, and red caliper finish provide both the stopping power and visual appeal to match any front big brake system.
