Restore maximum hydraulic brake line pressure and eliminate dangerous pedal fade with this premium Replacement Brake Master Cylinder (Part # 851820). Engineered specifically for heavy-duty Clark industrial lift trucks, this precision-machined cast-iron master cylinder translates foot pedal force into instant, dependable hydraulic stopping power across all wheel cylinders.
A failing, leaking, or internally bypassed brake master cylinder is a severe safety hazard that causes spongy brake pedals, pedal sinking to the floorboards, and catastrophic loss of stopping capability on loading ramps. Our aftermarket Clark master cylinders feature precision-honed internal bores and heavy-duty, fluid-resistant EPDM rubber piston seals designed to resist high pressure spikes and corrosive brake fluids without internal bypassing. We offer transparent pricing with fast, dependable shipping directly to your commercial facility.
