Product details
Check the 5.46-inch mounting centers before fitting this anodized Wilwood D154-DS brake caliper. The component is sold individually and uses 2.50-inch bore in its 1.04-inch rotor-width configuration. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another. This D154-DS floating caliper uses a single 2.50-inch stainless piston with a dust wiper seal and D154-shape pads. It replaces the matching GM metric brake arrangement only after the slider, rotor and hose connection have been checked. It is not an axle kit.

Fitment & Compatibility
This caliper requires the measured 1.04-inch rotor-width configuration and the matching floating bracket on 5.46-inch centers. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Confirm the M10 x 1.50 hydraulic inlet, pad outline and total piston area with the rest of the brake system before assembly.
