Product Description

The Wilwood 140-10941-DR is a big-brake rear disc conversion kit that combines high-performance AERO4 calipers with a functional internal parking brake. Perfect for classic truck builds, this kit fits large Chevy C10/C15 axles (2.42" offset) and delivers significant stopping power with a clean, integrated look.

The 14-inch SRP drilled and slotted rotors provide excellent heat dissipation, while the BP-10 pad compound ensures strong bite and fade resistance. With radial-mount calipers and forged aluminum construction, the setup delivers both rigidity and longevity. Parking is handled by an internal drum-style mechanism, keeping the design sleek and performance-focused.

Installation includes aluminum rotor hats, hardware, and detailed instructions. Because of the large rotor size, a minimum 18" wheel is recommended. This kit is ideal for custom builds, performance trucks, or restorations that demand modern braking performance with a parking-brake solution.
