Wilwood’s current pad page identifies CM composite-metallic material, characterized by high friction with a smooth initial response. The compound information emphasizes stainless-steel rotor applications and racing use. Match the actual caliper, rotor and operating duty before treating a powersports or industrial pad as a service-brake replacement.
Fitment & Compatibility
Match the PS1 caliper and the drawing’s retention feature. Wilwood identifies the current material as CM; no front or rear vehicle assignment is established by the caliper-only specification.
