Wilwood 140-9286-R DynaPro Radial 4-Piston Rear Disc Brake Kit 13.00" Red Calipers

The Wilwood 140-9286-R is a complete DynaPro Radial (DPR) rear disc brake kit featuring forged billet four-piston calipers in a bold red finish and 13.00" slotted rotors. Engineered as a high-performance rear brake upgrade, this kit delivers exceptional clamping power, firm pedal response, and superior stopping performance over the factory brake system.

The DPR rear axle kit is designed to retain full function of the OE parking brake, making it a seamless, street-legal upgrade. Caliper piston sizes are carefully selected to provide balanced rear brake bias ratios using the output from the stock master cylinder — no proportioning valve upgrades required for most applications. The kit also serves as the ideal companion to Wilwood front big brake upgrades, providing complementary performance and consistent style across all four corners.

Rotor and hat combinations are vehicle-specific, engineered for precise fitment with the DynaPro caliper mounting system. BP-10 compound brake pads are included and deliver high-friction performance across a wide operating temperature range, suited for both street driving and high-performance use.
