3-Ton Brake Master Cylinder for Dalian 30N-R Forklift

This 3-ton brake master cylinder is a direct OEM replacement for Dalian 30N-R series and other 3-ton capacity internal combustion forklifts equipped with hydraulic drum brake systems. The master cylinder converts mechanical pedal force into hydraulic pressure, distributing brake fluid through dual-circuit outputs to the front wheel cylinders for balanced, reliable braking under all load conditions. Constructed with a cast iron body featuring a precision-honed bore, this unit provides consistent pedal feel and responsive braking performance throughout the full range of operating temperatures encountered in warehouse, factory, and outdoor material handling environments.

The cylinder assembly includes a pre-installed piston with EPDM primary and secondary cup seals that maintain reliable fluid sealing throughout the service life, along with a dust boot that prevents contamination ingress at the push rod interface. The reservoir is an integrated design with a transparent nylon body that allows quick visual inspection of brake fluid level without removing the cap, and the screw-cap lid includes a vented diaphragm that equalizes internal pressure as fluid level changes during brake application and release. The outlet ports use standard M10x1.0 metric threads compatible with OEM brake line fittings, and the dual-port design enables separate front-left and front-right circuits for safety redundancy in the event of a single circuit failure.

Compatible with Dalian 30N-R, CPCD30, and equivalent 3-ton forklifts using drum-type front brake systems. Installation requires removing the old master cylinder, bench-bleeding the new unit before mounting, connecting the brake lines, and performing a full system bleed starting from the wheel farthest from the master cylinder. Always use fresh DOT 3 or DOT 4 brake fluid from a sealed container to prevent moisture contamination. After installation, check pedal height and free play according to the forklift service manual specifications.

Compatible Forklift Models

Each master cylinder is pressure-tested at 2000 PSI for leaks and bench-bled before packaging. The cylinder ships with outlet port dust caps installed to prevent contamination during transit, sealed in a VCI anti-corrosion bag within a foam-lined box. 12-month warranty against manufacturing defects. Installation tip: bench-bleed the master cylinder before installation by clamping it in a vise, filling with fluid, and slowly pumping the piston until bubble-free fluid emerges from both outlets.
