Brake master cylinder for P&H 703/704 R-200

The brake master cylinder 38Z335 functions as the primary hydraulic actuator within the braking system of heavy machinery. It converts the mechanical force applied to the brake pedal into hydraulic pressure, which is then transmitted through the brake lines to the wheel cylinders or brake calipers to engage the braking mechanism. This component is central to the operation of the hydraulic brake circuit, ensuring that the operator maintains control over the machine deceleration and stopping functions.

This component is compatible with several crane models including the P&H 703/704 R-200, P&H R-200, P&H R200, P&H RT200, Terex 703/704 R-200, Terex R-200, Terex R200, and Terex RT200. It is designed to integrate into the existing hydraulic architecture of these rough-terrain crane models to facilitate consistent brake pressure distribution.

In heavy equipment, the master cylinder acts as the interface between the operator input and the hydraulic braking force. By housing internal seals and a piston assembly, it maintains the necessary pressure levels to actuate the brakes across all wheels. Regular inspection of the master cylinder is standard practice to ensure the integrity of the hydraulic seal and the responsiveness of the braking system during operation.
