Restore maximum hydraulic braking power, precise pedal feel, and OSHA safety compliance to your material handling equipment with this premium Replacement Brake Master Cylinder (Part # 0309644). Engineered specifically for Hyster and Yale forklifts, this heavy-duty cast-iron cylinder assembly seamlessly converts your mechanical pedal force into the exact hydraulic pressure required to instantly stop a fully loaded machine.

A leaking, spongy, or internally bypassed master cylinder is a massive safety violation that will prevent your lift truck from stopping under load, risking catastrophic warehouse accidents. Don't risk operator safety or get hit with massive hidden shipping fees at checkout from other suppliers for heavy metal brake components. Our aftermarket Hyster master cylinders feature precision-honed internal bores and premium EPDM rubber cup seals designed to resist brake fluid contamination and withstand thousands of heavy braking cycles. We offer transparent pricing with fast, FREE shipping directly to your repair facility.

TECHNICAL SPECIFICATIONS & VERIFIED FITMENT:

• Part Number: 0309644 (Replaces HY0309644, 309644)

• Component: Hydraulic Brake Master Cylinder Assembly

• Equipment Fitment: Engineered for select Hyster and Yale Forklifts. (Please verify your specific model's parts manual for exact fitment).

Expert Tip: When replacing your master cylinder, it is mandatory to perform a complete bleed of the hydraulic brake lines. Installing a brand-new master cylinder without flushing out the old, moisture-contaminated brake fluid will instantly degrade the new internal rubber seals!
