Wilwood Rear Red Metric Brake Caliper/Pad Package for Custom D154 Brackets, 1.04-Inch-Wide Rotors

Red powder-coated D154 calipers provide the service-brake hardware in this Wilwood custom rear package. Two 1.12-inch pistons in each floating body work with included BP-10 pads. The kit is a caliper-and-pin set for the matching 1.04-inch-wide rotor arrangement; it does not convert an unmodified axle or add a 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

Verify the engineered rear brackets against DS844 and inspect the retained rotor mounting. The caliper must be centered correctly and slide without binding. Evaluate the selected rear piston area with the front brakes and master cylinder before installing a different caliper type. Check the M10 × 1.50 banjo connection, hose movement and sealing parts. Brake rotors and parking-brake hardware are separate choices. Use the actual wheel to confirm clearance, then bleed and test for correct brake balance.
