Wilwood Right Red DP6A Brake Caliper for 0.81-Inch-wide Rotor, 6 Stainless Steel Pistons

For a brake system using a 0.81-inch-wide rotor, this red Wilwood Forged Dynapro 6A provides 6 pistons with 1.38/1.00/1.00-inch bores. Right-hand mounting is specified. The caliper attaches on 5.25-inch lug centers. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Measure rotor width before comparing calipers. Verify the mount height, rotor centerline and available wheel space; a common piston count does not establish interchangeability.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.

PMB Performance has worked with parts and brake fitment for over 20 years. Supply the installed caliper identity and the rotor and bracket measurements for a practical compatibility check.
