Product details
Wilwood UTV4 calipers must be matched by width and mounting configuration. This black rear brake caliper for Can-Am Maverick X3 has 1.12/1.12-inch bore dimensions, an 8.75-inch mounting span and the 0.25-inch-wide rotor specification. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system. UTV4 is a forged four-piston hydraulic caliper used with the matching Wilwood rear UTV conversion. The replacement caliper requires the kit-specific bracket and rotor assembly; it is not a direct replacement for an unmodified factory brake.
