Wilwood friction pads are produced to specific chemical and physical material requirements to meet the high performance demands of racing disc brake systems. Because of the wide range of racing usage (short track, super speedway, dirt, drag) Wilwood has developed specific material compounds to meet specific needs.
Experimentation is often necessary to determine the optimal brake pads for an application. Such variables as caliper size, rotor type, rotor operating temperature, race duration, and driving habits all affect brake pad performance. Wilwood high performance brake pads are described in general; your actual selection should combine this information with your own testing and experience.
Brake pad performance is generally measured using its coefficient of friction (cf), i.e. the degree of friction (drag) between the pad and rotor. This friction varies with pad material, rotor material, and operating temperature. The pad descriptions (following the pad configuration drawings) are generally evaluated on the basis of a pad material coefficient of friction variance over a particular temperature range.
NOTE: All Wilwood brake pad sets with a “K” suffix on the part number are packaged four pads to a box, in axle sets. The diagram on the following page illustrates the outline dimensions of the backing plates and friction material on each type of brake pad.
