Frequently Asked Questions
Q: What is the bore diameter and piston area of the 5916211181 master cylinder?
A: The 5916211181 master cylinder has a 1.625 inch bore with 2.074 square inch piston area. Internal check valve and compensation port design allows brake fluid displacement of 8.5 cubic centimeters per full pedal stroke.
Q: Which forklift brands and brake system configurations use this master cylinder?
A: This master cylinder is compatible with Crown, Yale, Clark, and Mitsubishi electric and internal combustion forklifts with two-wheel or four-wheel hydraulic brake circuits rated 1,800 to 2,500 PSI. Confirm your brake line configuration and pedal linkage before ordering.
Q: What is the pressure output and fluid capacity?
A: The 5916211181 generates maximum pressure of 2,200 PSI under full pedal load with a 0.75 liter fluid reservoir capacity. Dual outlet ports allow independent control of front and rear brake circuits for balanced vehicle deceleration.
Q: What maintenance and troubleshooting steps apply to this master cylinder?
A: Check brake fluid level monthly and use DOT 3 or DOT 4 fluid meeting ISO 4925 specifications. Bleed air from circuits every 500 operating hours. Soft pedal feel, slow pressure buildup, or brake fluid leakage from the rear seal indicates internal wear or contamination.
Q: What is the typical service life and failure modes?
A: Under normal warehouse conditions, the 5916211181 operates 2,500 to 4,000 service hours before seal wear occurs. Primary piston cup seal failure causes loss of brake pressure. Water contamination or degraded brake fluid accelerates corrosion and reduces lifespan significantly.
