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 Dynalite - Side Inlet Calipers

The Billet Dynalite caliper is powerful, compact and super lightweight. Advanced computer engineering keeps this caliper extremely rigid, resulting in incredible brake torque at a bare minimum in weight, starting at 2.66 pounds. Internal fluid crossover eliminates external tubes and the four position, two-piece bleed screws allow for convenient mounting and easy bleeding. The Billet Dynalite uses standard quick change Dynalite pads, deep cup stainless steel pistons and high temperature seals, and has a black anodized finish. The time proven Dynalite caliper design is stronger and lighter than ever - ideal for Late Models, Modifieds, Sprints, Road Racers and Dragsters. View Billet Dynalite Calipers

Dynapro Dust-Boot Calipers

The Dynapro Dust-Boot (DP-DB) model of the Dynapro lug mount caliper was developed for applications that require or prefer a dust-booted piston. Dust-booted aluminum pistons provide added protection against road or track born dirt and debris on low to intermediate temperature range applications that may also operate in harsh environments. The pistons are clear anodized to eliminate corrosion while providing added lubricity for drag-free operation within the bores. The dust boots work in conjunction with high-temperature square faced internal seals in the caliper bores to provide optimum performance, ultimate reliability, and quick turn around at pad service intervals.

Forged DPHA Calipers

The Forged DynaPro Honda/Acura (DPHA) caliper represents the newest generation of calipers designed exclusively as a direct bolt-on for Honda and Acura models originally equipped with 262mm diameter rotors. These calipers bolt directly to the stock mounts on factory spindles, fit over the OE 262mm diameter rotor, accept the OE brake hose, and clear many factory aluminum 15” wheels. Designed around Wilwood’s proven DynaPro series four piston calipers, the forged billet bodied DPHA caliper delivers high-strength clamping force and positive stopping power. Four stainless steel pistons provide fully balanced pad loading, along with the corrosion resistance and thermal retardant qualities of the stainless alloy that will keep your calipers cooler and running trouble free for many more miles. Calipers work perfectly with most OE master cylinders and will maintain ABS function. DPHA calipers are available with either black, red or Competition Blue high-gloss, high-temp, brake fluid resistant sealed powder coat and feature Wilwood’s signature logo. View Forged DPHA Calipers
