Brake Slave Cylinder Repair Kit for Massey Ferguson 300, 4200 & 4300 Series Tractors

Description

When your brakes start getting spongy or you notice that pedal going closer to the floor than it used to, worn seals in your brake slave cylinders are usually the culprit. This comprehensive repair kit contains all the seals and components you need to rebuild your brake slave cylinders and restore that firm, confident pedal feel that keeps you safe in the field and on the road.

What You’re Getting

• Complete seal kit with all necessary rubber cups, seals, and gaskets for proper brake operation
• Premium materials specifically designed for agricultural hydraulic brake systems
• Direct replacement components that restore original braking performance
• Compatible with both LHM mineral oil systems used in these tractor series

Built for Real Farm Work

These Massey Ferguson tractors use a unique brake system where the slave cylinders are located inside the rear axle housing, which is why they require special LHM mineral oil instead of regular DOT brake fluid. Whether you’re running a compact 300 series utility tractor for loader work or operating a larger 4200/4300 series machine for row crops and heavy field operations, reliable brakes are essential for safe operation on hills, around livestock, and during road transport between farms.

Made to Last

This repair kit uses premium materials specifically formulated for LHM mineral oil brake systems, with seals engineered to withstand the unique demands of agricultural hydraulic systems including higher operating pressures, extended service intervals, and exposure to agricultural contaminants. The components are built to handle the temperature swings and constant vibration that come with farm work.

Installation Notes

Installation requires brake system disassembly and should only be performed by qualified technicians familiar with hydraulic brake systems. Critical safety note: This system requires LHM mineral oil brake fluid only – never use DOT brake fluids as they will damage seals and compromise brake performance. Always flush the entire brake system with fresh LHM fluid after repair. Many farmers successfully use 10W-30 transmission oil as a cost-effective alternative to expensive LHM fluid.
