Description
When your brake pedal starts feeling spongy or you notice brake fluid dripping from the master cylinder, it’s time to rebuild before you lose your brakes altogether. This repair kit gives you everything needed to restore your master cylinder to like-new condition, keeping you safe when hauling heavy loads or working steep ground.
What You’re Getting
- Complete seal and gasket set to rebuild your brake master cylinder, no need to hunt for individual parts
- Seals engineered to withstand higher operating pressures and extended service intervals typical of farm work
- Premium quality seals that resist brake fluid breakdown and maintain their seal over time
- Direct fit for the 4-pipe master cylinder design used on these tractor series
Built for Real Farm Work
This kit fits the 4-pipe brake master cylinder (part 3383079) used on Massey Ferguson 3000 and 3600 series tractors. These mid-sized workhorses handle everything from hay operations to loader work, and reliable brakes aren’t optional when you’re controlling heavy implements or navigating hilly terrain with a loaded wagon behind you.
Made to Last
This repair kit uses premium materials manufactured to meet stringent agricultural equipment standards. The seals are specifically engineered to handle the unique demands of agricultural hydraulic systems, including exposure to temperature extremes and the vibration that comes with farm work.
Installation Notes
Rebuilding a master cylinder requires careful attention to cleanliness—any contamination will compromise the entire brake system. Bench bleed the rebuilt cylinder before installation to remove air from the system. Plan to flush your brake system with fresh fluid while you’re at it, as old fluid can damage new seals.
