Description

If you’ve ever felt your brakes grab unevenly or noticed brake fluid weeping around the disc assembly, worn piston seals are likely the culprit. Brake pistons take serious abuse—they convert hydraulic pressure into the mechanical force that stops tons of moving tractor. A quality piston maintains its smooth finish and precise fit even after thousands of brake applications, but the seals that keep everything working right can wear out over time. This replacement seal keeps your brake piston properly sealed so you get the stopping power you need when you need it.

What You’re Getting

Precision-molded seal designed specifically for wet disc brake systems
High-grade rubber compound that resists brake fluid and hydraulic oil breakdown
Maintains proper hydraulic pressure for consistent brake feel and performance
Direct replacement for OEM brake piston seals—no modifications needed
Works with related brake components like discs and wear plates in your system

Built for Real Farm Work

This seal fits the wet disc brake systems found on New Holland T7 and TM series tractors, plus Case IH Puma and MXM models. These medium to heavy-duty tractors are designed for diverse agricultural operations including row-crop farming, livestock management, hay production, transport duties, and intensive field work. When you’re running 110 to 210 horsepower through demanding conditions, you need brakes that respond instantly and release completely. Whether you’re hauling grain carts down hills or making sharp turns with a loader full of round bales, reliable brakes are essential for safe operation.

Made to Last

Farm tractors demand seals that can handle constant pressure cycling, temperature swings, and exposure to hydraulic fluids. This seal is manufactured from compounds specifically formulated to resist the chemicals found in modern brake systems while maintaining flexibility through thousands of brake applications. The material won’t swell, crack, or harden like generic seals that aren’t designed for agricultural hydraulics.

Installation Notes

Always check the brake cylinder bore condition before installing a new piston—rough or corroded bores will destroy pistons quickly. Replace all seals when you’re in there, and use only the brake fluid specified in your manual. Clean everything thoroughly during assembly, and don’t forget to bleed the system properly once you’re done. This seal works with the other brake components in your system—the O-rings, brake discs, and wear plates all work together to give you reliable stopping power.
