When your tractor’s pulling to one side during braking or you’re fighting uneven stopping power, chances are one of your brake slave cylinders has given up the ghost. This right-hand replacement is specially built for those late-model MF 300 series tractors where the slave cylinders sit inside the rear axle housing – which is why they need LHM mineral oil instead of regular brake fluid. Get both sides working together again and you’ll have the safe, straight stops you need when hauling heavy loads or working around the farmyard.
What You’re Getting
- Right-hand side replacement that pairs perfectly with your left brake for balanced stopping power
- Heavy-duty construction built to handle the hydraulic pressures and vibration of daily farm work
- Precision-machined bore ensures consistent brake engagement every time you press the pedal
- Designed specifically for LHM hydraulic fluid – the mineral oil your 300 series needs
- Direct bolt-in replacement that fits just like your original equipment
Built for Real Farm Work
This slave cylinder fits late Massey Ferguson 300 series tractors including models 340, 342, 350, 352, 355, 360, 362, 365, 375, 390, 390T, 398, and 399 – the workhorses that handle everything from pulling loaded grain wagons to operating on steep hillsides with a round baler in tow. These mid-size tractors see it all – cultivating, planting, hay operations, loader work, and everything in between where reliable braking keeps you safe.
Made to Last
Farm brake systems take a real beating from dust, moisture, and constant use in demanding conditions. This replacement cylinder uses quality seals specifically designed to work with mineral oil, not regular brake fluid. The precision-machined internal components ensure smooth operation and consistent brake pad pressure, while the robust construction handles the environmental challenges that come with agricultural work.
Good to Know
Remember – this system uses LHM mineral oil, not DOT brake fluid. Using the wrong fluid will cause immediate seal failure and brake loss. Many farmers successfully use clean 10W-30 transmission oil as a cost-effective alternative to expensive LHM fluid. If one cylinder’s failed, consider replacing both sides since they typically wear at similar rates. Don’t forget to bleed the system thoroughly after installation and check your master cylinder while you’re at it.
