Wilwood 140-12049 Combination Parking Brake Rear Disc Brake Kit

The Wilwood 140-12049 is a rear disc brake kit featuring Wilwood's Combination Parking Brake (CPB) caliper design — a hydro-mechanical system that delivers both hydraulic stopping power and an integrated mechanical parking brake lock in a single caliper unit. This eliminates the need for traditional internal drum-style parking brake setups, making it an ideal solution for rear-wheel drive axles where shoe-style parking brakes are impractical or incompatible.

Key Features:

• Hydro-mechanical CPB calipers — use hydraulic pressure from the master cylinder for primary braking, with an internal mechanical lock for secure parking brake engagement
• 12.19-inch one-piece rotor assemblies — 0.81-inch thick rotors with integral hats for a clean, lightweight design
• BP-10 high-friction compound brake pads — designed for strong, consistent stopping performance
• Engineered for rear-wheel drive axles not compatible with internal shoe-style parking brakes
• Provides balanced brake performance — styled and sized to complement Wilwood front big brake upgrade kits
• May fit some 16-inch wheels — verify wheel clearance using the kit installation instructions diagram before installation

Wilwood's CPB rear brake kits are a purpose-built solution for performance builds and custom applications where a conventional parking brake mechanism won't work. The matched rotor and caliper design integrates seamlessly with Wilwood front big brake kits for a complete, cohesive brake system upgrade.
