Wilwood Red TC6R Right Brake Caliper with Rear-Mount Orientation and 1.88/1.62/1.62-Inch Bores

This Wilwood TC6R is a right-hand 6-piston brake caliper with a red finish for a nominally 1.38-inch-wide rotor. Its 8.27-inch radial mounting centers and 1.88/1.62/1.62-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.

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

Check mounting-center spacing and bracket offset together, then confirm the pad sits fully on the rotor friction surface. Piston area must suit the master cylinder and front-to-rear brake balance.

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