Compound Characteristics



Compound Data Sheet
Use & Caution
  • Medium friction, highest effective temperarture range in medium temperature pad group.
  • Smooth engagement, torque curve increases in relation to temperature
  • Moderate wear rate at high temperature
  • Medium friction, highest effective temperarture range in medium temperature pad group.
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 Narrow Dynalite Calipers

Wilwood’s Billet Narrow Mount Dynalite (NDL) caliper combines the lightweight, high torque performance of our Dynalite Series Calipers, but utilizes a thicker pad design and bolts directly onto standard Superlite 3.50” mounts. Caliper weights starting at 3.50 pounds, yet provides tremendous brake torque. The caliper is extremely compact and will easily mount in limited clearance applications. Its computer generated billet design incorporates internal fluid crossover passages to eliminate external tubes, while the extra thick 0.63” (16,0 mm) Dynalite pad is securely held in by the bridge bolt design. Standard Wilwood features include deep cup stainless steel pistons, high temperature piston seals and black anodized finish. The caliper is available in 1.75, 1.62, 1.38 and 1.12 inch piston bores for 1.25, .81, .50 and .38 inch rotor widths. The Billet NDL is ideal for many racing applications, including Late Models, Modifieds, Sprints, Off Road and Road Racers. View Narrow Dynalite Calipers

Billet Narrow Dynalite Radial Mount Calipers

Wilwood's newly redesigned Billet Narrow Mount Dynalite (NDLR) Radial Mount caliper series continues to grow in popularity in Sprint & Midget inboard applications. Starting at 2.70 pounds, this compact and lightweight design is now available in a radial mount configuration. Engineered specifically for .38” and .810” width rotors, with a single split bridge area for strength. This spacer-less design maximizes rigidity and strength. Quick-Silver Nickel plating or Type 3 Anodize further enhances the durability of the caliper. Billet NDLR calipers can be directly mounted over studs, or used with a radial mount bracket kit in place of a tab mount caliper. View Narrow Dynalite Radial Mount Calipers
