Product details
The red version of this Wilwood rear D154 kit supplies twin-piston floating calipers, BP-10 pads and slide pins. It is built around a 0.81-inch-wide rotor-width configuration and two 1.12-inch bores in each caliper. The package is for a correctly prepared rear metric-brake mount and provides hydraulic service braking without a cable parking lever. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility
Check the custom axle brackets and rotor alignment against DS845 before selecting the calipers. Mounting ears must hold the bodies squarely while allowing their normal sliding movement. The rear piston area must work with the complete hydraulic system, including the front calipers and master cylinder. Verify the M10 × 1.50 hose attachment, sealing washers and route. Rotors, fabrication work and any required parking brake are additional. Complete an actual wheel-clearance check and controlled brake-balance tests after bleeding.
