Product details
Bill Wood started Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street vehicles and specialized installations. Four replacement pads for the specified Wilwood caliper configuration with shims. Each part must be selected to work with the complete brake system and its requirements.
This part is selected by its SC-series or other specifically listed mechanical/parking-caliper interface. The current page identifies CM material; Wilwood’s parts-search text calls it SM. These inconsistent material labels and .27/.120-inch thickness descriptions require confirmation before making a substitution.

Fitment & Compatibility
This shim-equipped SC1/SC2/SC3 selection is separately identified in Wilwood’s official parts search. Overall pad thickness is .27 inch on the drawing and exact page; the search uses .120 inch. Confirm the required assembly and friction material, described as SM there and CM on the pad page.
Use in a parking mechanism must follow that mechanism’s instructions. The general CM compound chart does not establish dynamic service-brake or street approval for a mechanical parking-caliper installation.
