Description

When you press the brake pedal on your Massey Ferguson and feel something’s not quite right—maybe a spongy feel, uneven braking, or worse yet, the pedal going to the floor—there’s a good chance your brake slave cylinder needs attention. This is the hydraulic workhorse that takes pressure from your master cylinder and applies the actual braking force to stop your tractor safely, whether you’re pulling a loaded wagon down a hill or navigating tight spaces around the farmyard.

What You’re Getting

Direct replacement designed specifically for LHM mineral oil brake systems—no mixing with regular brake fluid
Precision-machined bore and quality seals built to handle the demands of daily farm work
Compatible with the unique internal slave cylinder design used on 4200 and 4300 series tractors
Heavy-duty construction that stands up to hydraulic pressure cycles and agricultural conditions

Built for Real Farm Work

Your Massey Ferguson 4200 or 4300 series tractor is built for serious work—from field operations with heavy implements to transport duties with loaded trailers. These mid-range tractors handle everything from hay production to row-crop farming, and reliable brakes aren’t optional when you’re working with that much weight and power. The slave cylinder is a critical part of the system that lets you stop confidently in any situation.

Made to Last

Unlike regular brake cylinders, this one’s specifically engineered for LHM mineral oil systems. The seals are formulated to work with mineral oil’s unique properties, preventing the degradation that happens when you use the wrong fluid type. It’s built to agricultural equipment standards, which means it can handle the extended service intervals, higher pressures, and tougher conditions that come with farm equipment.

Good to Know

This is an LHM mineral oil system—never use DOT 3, DOT 4, or any standard brake fluid, as it’ll destroy the seals immediately. Many farmers successfully use 10W-30 transmission oil as an alternative to expensive LHM fluid. When you’re doing the replacement, it’s smart to check your brake master cylinder and pull rod seals at the same time, since they often wear together. Always bleed the system thoroughly after installation and test your brakes in a safe area before heading back to work.
