Product details
Red powder coat finishes this rear-use D52 twin-piston caliper. It combines a nominal 1.28-inch rotor-width channel with two 1.25-inch stainless pistons, preserving the smaller hydraulic area needed by a matching rear brake layout. Wilwood Engineering is a Camarillo, California-based designer and manufacturer of disc brake systems, founded by Bill Wood in 1977. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications.
Technical Details

Fitment & Compatibility
Check bracket alignment and sliding travel as well as rotor width. The caliper uses a 7/16-20 banjo inlet; choose the hose and master-cylinder combination to suit the complete front-to-rear brake balance.
