Product details
With 1 piston and 2.75-inch bore dimensions, the anodized Wilwood D52-R brake caliper must be matched to the brake system rather than selected by finish alone. Its 0.81-inch rotor-width specification is separate from rotor diameter. The D52-R is a single-piston floating race caliper using the D52 pad outline and stock-height mounting geometry. Slide pins and vibration dampeners are not supplied. Match the racing rules and the complete sliding support before installation. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement.

Fitment & Compatibility
Compare the caliper drawing with your floating bracket before ordering. The 7.06-inch mounting centers and 2.75-inch bore must suit the installed rotor offset and hydraulic system. Axle placement is determined by the engineered brake package, not by a generic caliper designation. A suitable pad sweep and clearance inside the wheel must be verified independently of rotor width.
