Wilwood 140-12567 D154 Pro Series Rear Disc Parking Brake Kit

The Wilwood 140-12567 D154 Pro Series Rear Disc Brake Kit with Integral Parking Brake is a complete rear disc brake conversion engineered for both high-performance street driving and demanding off-road use. Designed for non-ABS Dana 35 rear axles, this kit delivers a true bolt-on upgrade with full compatibility with the OE master cylinder — no custom hydraulic work required.

At the heart of this system are 12.19-inch diameter one-piece rotors paired with two-piston floating mount D154 calipers, providing serious stopping power suited to larger wheel and tire packages. The forged D154 dual-piston calipers offer exceptional thermal management and braking force for both street and trail conditions.

Key Features:

• 12.19" diameter rotors for maximum brake surface and heat dissipation
• Two-piston floating mount D154 calipers for balanced, progressive braking feel
• Integral internal shoe parking brake system hidden neatly inside the rotor hat for a clean, OEM-like appearance
• Superior static holding power for reliable parking brake performance
• Bolt-on installation with no drilling required for non-ABS Dana 35 axles
• OE master cylinder compatible — works with factory hydraulic output
• Complements vehicles already running Wilwood D52 or D154 calipers on OE or aftermarket spindles
• Available in multiple caliper finish and rotor design options for style customization

The cleverly concealed internal drum-in-hat parking brake mechanism maintains a clean underbody appearance while delivering dependable stationary holding power — a critical feature for off-road builds where the vehicle may be parked on uneven terrain. This kit pairs seamlessly with Wilwood D52 or D154 front caliper setups for a cohesive, matched brake system across all four corners.
