The above friction data (μ) was recorded through braking cycles from 95 mph to 40 mph at a 0.5g deceleration. Snubs were consecutively done until rotor temperature reached 1300°F. This graph represents average data and is for general trend visualisations only comparing Wilwood pads. Chart data should not be used in comparison with other manufacturer's data. Test conditions, variables, and environment can affect test results.

Temperature range and overall friction value are the primary considerations for pad selection. The pads must maintain the proper amount of friction for stopping power within the temperatures that will be realized on the track. Overall wear rate must also be considered. For most asphalt and road race applications, compounds in the high-temperature range over 1000°F 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, improved cooling, a heavier rotor, or a higher temperature range pad may become necessary.

Billet Go-Kart Calipers

Our Kart/Jr. Dragster Caliper is designed specifically for racing. A unique self retracting and adjusting piston system has been incorporated which enables the piston to retract as the brake line pressure is reduced. The caliper can be mounted on either side of the vehicle and comes in three rotor widths. At just 1.20 pounds, the caliper comes with high performance, high friction brake pads. Additional features include deep cup stainless steel piston for reduced heat transfer, cotter pin, pad retainer, internal fluid passage and blue anodized finish. A specifically designed master cylinder is also available for use with this caliper. View Kart Calipers
