Product Description
The brake master cylinder (1287843C92) is a critical hydraulic component that converts pedal pressure into braking force, ensuring smooth and responsive stops for Case IH Tractors (380B, C50-C100, 3220, etc.).
How It Works:
When the brake pedal is pressed, the master cylinder’s piston compresses brake fluid, transmitting hydraulic pressure to the wheel cylinders or calipers. This OEM-equivalent master brake pump is precision-engineered for heavy-duty tractor applications, featuring:
✔ Aluminum construction – Resists corrosion & withstands high-pressure conditions
✔ ISO9001-certified – Ensures consistent quality & durability
✔ Direct-fit replacement – Matches OE specs for seamless installation
Ideal for:
✔ Tractor repair shops needing reliable brake components
✔ Agricultural equipment wholesalers stocking OEM-grade parts
✔ Fleet maintenance providers servicing Case IH 380B, C50-C100, 3220 models
