Product details
The D52/D154 slide-pin O-ring kit supplies eight rings for the caliper’s sliding-pin locations. Four small and four large rings are specified for the pack, with listed IDs of 0.362 and 0.630 inch. Their function and profile differ from the pressure seals used around the hydraulic piston. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Confirm the exact D52 or D154 caliper and slide-pin arrangement before replacing the rings. Inspect pin condition, housing grooves and free caliper movement during service. Do not select these as hydraulic piston seals or infer brake-fluid requirements from them; use the applicable caliper maintenance instructions for installation and lubrication.
For help identifying the correct brake component, provide the caliper markings and installation dimensions. PMB Performance has over 20 years of experience with parts and brake-system details.
