Description

When your left brake pedal starts feeling spongy or won’t hold on slopes, you know it’s time to rebuild that slave cylinder. A failing brake means more than just inconvenience – it’s about losing the steering control you need when backing up to a grain cart or working on hillsides with heavy implements. This repair kit gets your left-hand brake working like new again.

What You’re Getting

Complete seal kit specifically designed for LHM mineral oil systems – no swelling or degradation
All components needed for a proper rebuild that’ll last for years
Restores firm pedal feel and reliable stopping power when you need it most
Direct fit for 4200 and 4300 series left-hand brake slave cylinders

Built for Real Farm Work

Your 4200 or 4300 series tractor handles serious work from intensive row crop farming to livestock management and heavy-duty field operations, frequently working steep terrain with heavy loads during cultivation, harvesting, and material transport. Independent left and right brakes give you the turning radius needed in tight spots around buildings and when maneuvering with front-end loaders.

Made to Last

This repair kit uses premium materials specifically formulated for LHM mineral oil brake systems, engineered to withstand the unique demands of agricultural hydraulic systems including higher operating pressures, extended service intervals, and exposure to agricultural contaminants. The seals maintain their integrity in mineral-based fluid without the breakdown you’d get from using incorrect components.

Good to Know

Critical safety note: This system requires LHM mineral oil brake fluid only – never use DOT 3, DOT 4, or DOT 5 brake fluids as they will damage seals and compromise brake performance. Clean the cylinder bore thoroughly and check for scoring before assembly. When installing seals, pay attention to orientation – backwards installation guarantees failure. After rebuild, proper bleeding starting with the wheel furthest from master cylinder is essential for firm pedal feel.
