Clutch Master Cylinder 711W30715-6152 HOWO T5G SITRAK C7H

Clutch master cylinder 711W30715-6152 is the hydraulic control unit of the clutch system for Sinotruk HOWO T5G and SITRAK C7H heavy-duty trucks. Mounted at the clutch pedal, it converts pedal movement into hydraulic pressure that actuates the clutch slave cylinder, delivering smooth clutch separation and precise gear engagement. A worn master cylinder typically shows up as a soft or spongy pedal, difficulty shifting, fluid leakage near the firewall, or the pedal sinking to the floor. This replacement unit matches original factory drawing standards: aluminum alloy housing with anodized corrosion protection, precision-machined piston bore, high-temperature rubber seals, integrated fluid port and pre-wired connector, with the push rod and dust boot included. Mounting holes, pipeline interface and push rod position are identical to the original part, so replacement is direct without modification.
