Product Details

The Wilwood 140-14591 CPB Rear Brake Kit delivers a complete, bolt-on rear disc brake upgrade built around Wilwood's combination hydro-mechanical parking brake caliper technology. Designed primarily for front-wheel drive vehicles and select rear-wheel drive axles where traditional internal shoe-style parking brakes are not practical, this kit provides a clean, high-performance solution that integrates service braking and parking brake functions into a single compact caliper assembly.

The Combination Parking Brake (CPB) caliper uses hydraulic pressure from the vehicle's master cylinder for normal service stopping power, while an internal mechanical lock mechanism engages independently to hold the vehicle stationary as a parking brake. This eliminates the need for a separate drum-in-hat or shoe-style parking brake system, making it ideal for custom builds, brake conversions, and performance upgrades on FWD platforms.

Key Features:

  • Combination hydro-mechanical parking brake calipers — hydraulic service braking with integrated mechanical parking brake lock
  • 12.19" two-piece rotor assemblies with lightweight aluminum hats for reduced unsprung weight
  • High-friction BP-10 compound brake pads included for strong, consistent stopping performance
  • Oversized rotor design provides increased thermal capacity and fade resistance
  • Engineered for front-wheel drive vehicles and select rear-wheel drive axles incompatible with internal shoe parking brakes
  • Balanced brake bias when paired with Wilwood front big brake upgrade kits
  • Complete bolt-on kit with all necessary hardware for a straightforward installation

The Wilwood CPB Rear Kit is an excellent complement to Wilwood's front big brake upgrade kits, providing matched style and properly balanced brake performance front to rear. Whether you're building a dedicated track car, a street performance vehicle, or converting to a full disc brake system, the 140-14591 delivers the reliability and engineering quality Wilwood is known for.
