Wilwood TX6R Right Brake Caliper, Red / 1.62/1.38/1.38-Inch Bore / 1.38-Inch Rotor Width

For a brake system using a 1.38-inch-wide rotor, this red Wilwood TX6R provides 6 pistons with 1.62/1.38/1.38-inch bores. Right-hand mounting is specified. The caliper attaches on 9.63-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.

The TX6R is a six-piston radial-mount caliper developed for heavy truck, SUV and specialized severe-duty brake systems. Type 10120 pads provide its large friction package; installation still requires a matching rotor, bracket and hydraulic design.

Fitment & Compatibility

Check pad depth against the rotor’s usable friction annulus. Rotor-hat clearance, mounting offset and the wheel’s inner profile must also be checked with the caliper drawing.

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.
