Wilwood TC6R Left Six-Piston Brake Caliper in Red, Front-Mount Configuration

Red finish and 1.75/1.38/1.38-inch bores distinguish this Wilwood TC6R configuration. It is a left-hand 6-piston brake caliper for 1.38-inch-wide rotors, with 8.27-inch radial attachment centers. 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.

Wilwood specifies front mount clocking for this left-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.

Fitment & Compatibility

Compare the existing caliper’s piston area, rotor capacity and mounting pattern. Matching the body family alone does not guarantee that the replacement will clear the wheel or preserve pedal travel.

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

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.
