Dexter K71-131-00 Right Hand Wheel Cylinder Assembly, Aluminum, Fits 10 Inch and 12 Inch Uni-Servo Trailer Drum Brakes

The Dexter K71-131-00 is a right hand wheel cylinder assembly built for trailer drum brake systems using uni-servo brake actuation. It is machined from aluminum for corrosion resistance in wet, road-salt, and marine-trailer environments where steel cylinders are prone to rust and seizing. This cylinder is sized to work with both 10 inch and 12 inch uni-servo drum brake assemblies, making it a common replacement part for trailers using this brake configuration.

This is a right-side-specific part. The internal piston and actuating linkage of a uni-servo wheel cylinder are oriented for one side of the axle, so this K71-131-00 assembly is designed for right hand (right wheel) installation only. A separate left hand cylinder is required for the opposite side of the trailer; do not install this part on the left wheel position.

The assembly is supplied as a complete unit, allowing installers to replace a worn, leaking, or seized cylinder without sourcing individual internal components separately.
