Wilwood TC6R Right Brake Caliper, Rear-Mount Orientation with Black Finish and 1.75/1.38/1.38-Inch Bores

Match this black Wilwood TC6R to a brake assembly requiring 1.38-inch rotor width and 1.75/1.38/1.38-inch pistons. The right-hand 6-piston caliper uses 8.27-inch radial mounting rather than a vehicle-specific adapter supplied as a kit. Wilwood Engineering’s disc brake range includes calipers, rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977 in California; it is based in Camarillo and serves motorsport, street-performance and specialized brake applications.

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.

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

Set up the brake assembly around the specified rotor and pad geometry. Check the mount drawing and wheel envelope, and confirm that the piston area suits the rest of the hydraulic system.

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