[More Info]

Designed, engineered and manufactured in the U.S.A., this floating die cast aluminum caliper is a strong, compact, inexpensive answer to the braking needs of recreational, agricultural and industrial vehicles. Features of this single piston design include availability of either 1.06”, 1.19” or 1.25” bore size, fitted dust seal to prevent ingress of environmental contamination, dual bleed fittings for versatility in mounting position and fluid inlets in M10 x 1.0 banjo.

The mounting system features corrosion resistant slide pins floating in viscoelastic rings mounted in the ears of the body for smooth, rattle-free operation. This system controls pad knock-back to retain a consistent pedal or hand lever feel throughout the life of the pads. Weight: from 1.1 pounds. Rotor thickness range: .15” to .25”
