Compound Data Sheet

  • Formulated for Power Sports, Industrial and Automotive Parking Brake applications.

  • Medium -high friction compound with a flat torque and consistent response throughout the entire temperature range.
  • Less agressive alternative to A or H compounds.
  • Long wear rate for severe duty, sustained high-temperature braking.
  • Performs best when initially bedded on new rotors or used rotors that have only been run with J compound.
Compound Temperature Range & Torque Values
Temperature range and overall friction value are the primary considerations for pad selection. The pads must be capable of maintaining the proper amount of friction for stopping power within the temperatures that will be realized on the track during the event. Then, overall wear rate must be considered. For most asphalt and road race applications, compounds in the high temperature ranges over 1000°F range are usually necessary. Dirt track, drag race, and street performance applications usually operate at temperatures between 500° and 1000°F. Keep in mind that these are general ranges, and not absolute values. Many factors and unforeseen influences can affect brake temperatures. The best indicator for pad selection will always be on track performance. If pad fade (friction loss) due to overheating occurs, then improved cooling, a heavier rotor, or a higher temperature range pad may all become necessary.

Billet Spot Caliper Caliper

Wilwood’s 1.75” diameter single piston Billet Spot Caliper is ideal for Micro and Mini Sprint, Kart, Off Road, Motorcycle, Drag Race Spindle Mount and industrial applications. Designed for light duty use, this floating caliper weighs just 1.20 pounds and holds a round .25” thick, .7 cubic inch brake pad, and accommodates rotors from 6.00” to 13.00” diameter and widths starting at .12”. Maximum rotor width can be adjusted by specific bracket and spacer dimensions. The pads are held in place by stainless steel 10-24 x .38” long flat head cap screw (screws are included), and the caliper is available black anodized. View Billet Spot Caliper Calipers
