Wilwood Dynapro Dust Seal Caliper, Black, 1.00–1.10-Inch Width and 5.98-Inch Mount

This Wilwood Dynapro Radial Dust Seal is a 4-piston brake caliper with a black finish for a nominally 1.10-inch-wide rotor. Its 5.98-inch radial mounting centers and 1.00-inch piston bores must match the brake assembly. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

This four-piston radial Dynapro includes piston dust wipers. The radial mounting centers are common to several rotor-width and radius versions, so bracket height, pad sweep and actual rotor dimensions must all be compared.

Fitment & Compatibility

For a replacement, compare the entire caliper specification rather than the finish or logo. On an adapted system, establish rotor alignment and piston-area requirements before choosing the mounting bracket.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
