Wilwood Red Dynalite Internal Four-Piston Caliper, 1.12-Inch Bore / 1.98-Square-Inch Hydraulic Area

Choose this Wilwood Forged Dynalite Internal when the installation calls for 1.12-inch pistons and 0.81-inch rotor width. The red 4-piston body uses a 5.25-inch lug pattern; check its complete geometry before substituting another caliper. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Use the caliper drawing to compare the mounting holes and body envelope with the installed brake assembly. Confirm piston sizes and brake balance before changing to a different bore configuration.

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

This four-piston Dynalite uses internal fluid transfer in a spacerless body. Its 5.25-inch mounting pattern is only one compatibility dimension: rotor position, body clearance and hydraulic area also need to agree.

Ask PMB Performance for help comparing this caliper with your existing assembly. Our over 20 years of experience are most useful when you provide rotor size, mounting details and the current piston configuration.
