Product details
For a brake system using a 1.38-inch-wide rotor, this red Wilwood TC6R provides 6 pistons with 1.75/1.38/1.38-inch bores. Right-hand mounting is specified. The caliper attaches on 8.27-inch radial centers. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.
TC6R calipers use six differential-bore stainless pistons in a radial-mount body intended for heavy truck and SUV brake packages. Six bridge bolts join the body, and replaceable steel bridge plates protect the pad abutments.

Fitment & Compatibility
Measure rotor width before comparing calipers. Verify the mount height, rotor centerline and available wheel space; a common piston count does not establish interchangeability.
Wilwood specifies rear mount clocking for this right-hand caliper. This is its orientation around the spindle, not a designation of the vehicle’s front or rear axle. Match the intended rotor rotation and upper bleed position.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
PMB Performance has worked with parts and brake fitment for over 20 years. Supply the installed caliper identity and the rotor and bracket measurements for a practical compatibility check.
