Wheel cylinder assembly for Lorain LRT-275D

The wheel cylinder assembly is a hydraulic component within the drum brake system of heavy machinery. It functions by converting hydraulic pressure from the master cylinder into mechanical force, which pushes the brake shoes against the wheel drum to create the friction required to decelerate or stop the machine. This part, identified by part number 207822, ensures that the braking force is applied effectively to the wheel assembly.

This component is engineered to fit Lorain LRT-275D, RT130, and RT225 cranes, as well as the corresponding Terex RT130 and RT225 models. It is designed to integrate into the existing hydraulic brake circuit to maintain consistent pressure distribution across the brake shoes.

In hydraulic drum brake systems, the wheel cylinder serves as the actuator at each wheel. When the operator engages the brake pedal, fluid is forced into the cylinder, causing internal pistons to extend and move the brake shoes outward. Proper function of this assembly is necessary for the overall responsiveness of the braking system in rough-terrain cranes.
