Wilwood 140-14591-D CPB Rear Disc Brake Kit 12.19" Drilled Rotor with Parking Brake

The Wilwood 140-14591-D CPB Rear Brake Kit delivers a complete bolt-on rear disc brake solution featuring a combination hydro-mechanical parking brake caliper design. The caliper uses hydraulic pressure from the master cylinder for primary stopping power while an integrated internal mechanical locking mechanism serves as the parking brake — eliminating the need for a separate drum-in-hat or external parking brake assembly.

Designed for FWD and Select RWD Applications:

Wilwood CPB kits are engineered specifically for front-wheel drive platforms and select rear-wheel drive axles where traditional internal shoe-style parking brakes are impractical or incompatible. This makes the CPB kit an ideal solution for modern performance builds and brake conversion projects where a clean, integrated parking brake is required.

Key Features:

• Rotor Diameter: 12.19 inches
• Rotor Style: Drilled — improves heat dissipation and wet-weather bite
• Rotor Construction: Oversized two-piece assembly with lightweight aluminum hat
• Brake Pads: High-friction BP-10 compound included
• Caliper Type: Combination hydro-mechanical parking brake (CPB) caliper
• Parking Brake: Internal mechanical lock — no separate drum or shoe hardware required
• Engineered to complement Wilwood front big brake upgrade kits for balanced system performance
• Bolt-on installation compatible with standard hand tools

The 140-14591-D is part of Wilwood's bolt-on brake kit lineup, where precisely matched components are engineered together to deliver superior braking performance and a custom appearance. The drilled rotor variant (suffix "-D") provides enhanced thermal management and a performance aesthetic to match front big brake kit upgrades.
