Description

When your tractor’s trailer brake valve starts giving you trouble—whether it’s sticking, leaking, or just not providing the control you need—this kit gives you everything to get it working right again.

What You’re Getting

Complete 16mm seal set designed specifically for hydraulic trailer brake valves
High-quality seals that handle the pressure and heat of constant braking

Built for Real Farm Work

This repair kit works with a wide range of Massey Ferguson tractors from the smaller 300 series utility models up through the big 8100 series row-crop machines. Whether you’re hauling grain carts during harvest, pulling manure spreaders across fields, or moving hay wagons during cutting season, proper trailer brake control keeps you safe and legal on farm roads and highways alike.

Made to Last

Farm trailers see some serious abuse—heavy loads, frequent stops, exposure to dust and moisture, plus long periods sitting idle between uses. These seals are built to handle all of that without breaking down or losing their ability to hold pressure. The 16mm size is engineered for the hydraulic pressures your brake system generates when you really need to stop.

Good to Know

Before you start the repair, make sure your hydraulic system is clean—contaminated fluid can damage new seals quickly. Take your time during reassembly and don’t over-tighten connections. A good rule of thumb is to test the system at low pressure first to make sure everything’s sealed properly before putting it back into full service. Keep some brake fluid handy because you’ll likely need to bleed the system after the repair.
