Description
If you’ve ever felt your brake pedal go soft when pulling a loaded grain cart down a hill or noticed your tractor pulling to one side when braking, it’s time to look at your master cylinder. This servo hydraulic unit is the heart of your Case MX series brake system, delivering the hydraulic power assist that makes even heavy braking feel effortless and keeps you safe on steep ground.
What You’re Getting
- Servo hydraulic design multiplies your pedal force for powerful, responsive braking even with heavy loads
- Precision-machined components ensure consistent brake pressure and eliminate that spongy pedal feel
- Heavy-duty construction built specifically for the demanding conditions of farm work
- Direct replacement part—bolts right in where your original master cylinder was mounted
Built for Real Farm Work
Your Case MX100, MX110, MX120, or MX135 handles serious work—pulling loaded wagons during harvest, operating a front loader, or pushing through heavy tillage. These mid-size tractors need brakes that can handle quick stops in the farmyard and controlled descents on hillsides. The servo hydraulic system gives you the stopping power you need without wearing out your leg on long days.
Made to Last
Master cylinders on farm tractors take serious abuse from vibration, temperature swings, and constant pressure cycles. This replacement features the same servo hydraulic technology as your original, with robust internal seals and corrosion-resistant components that stand up to years of daily use.
Installation Notes
This is a direct replacement for your original servo hydraulic unit. Before installation, have your brake fluid ready and plan to flush the entire system with fresh fluid. Remember to bench-bleed the new cylinder before mounting to prevent air locks, and always test your brakes thoroughly in a safe area before heading back to work.
