Product Description

The Wilwood 140‑11403‑DR is a rear disc conversion kit that integrates a high-performance hydraulic caliper with a functional mechanical parking brake. Its forged Dynapro low-profile calipers deliver strong braking force while fitting within tight rear-end packaging.

The 11″ drilled and slotted rotors provide improved cooling and fade resistance, while the BP‑10 pads ensure reliable stopping power. The internal shoe-style parking brake keeps the rear clean and sleek, avoiding bulky external components.

Ideal for classic muscle cars, custom builds, or street/strip applications that require modern braking with integrated parking brake functionality. Requires minimum 14″ wheels for clearance. Proper pad bedding and adjustment of parking shoes are recommended for optimal performance.
