Description
Nothing gets your attention faster than a spongy brake pedal or that sinking feeling when you press the brakes and they’re not quite there. When brake piston O-rings start going bad, you’ll lose stopping power right when you need it most—whether you’re hauling a loaded trailer down a hill or just trying to stop safely at the end of the field.
What You’re Getting
- Precision-sized small O-ring that seals the brake piston properly
- Made from brake fluid-resistant compound that stays flexible over time
- Direct replacement—no guesswork on fit or installation
- Works with the large O-ring to provide complete brake system sealing
Built for Heavy-Duty Work
This O-ring fits the workhorse tractors in John Deere’s lineup—the 6800 through 6930 series machines that handle everything from heavy tillage to transport work. These are the tractors pulling chisel plows, running big planters, and hauling grain carts, so reliable brakes aren’t optional.
Made to Last
Brake O-rings take a beating from high hydraulic pressure, heat from heavy braking, and constant exposure to brake fluid. This O-ring uses the right rubber compound to resist brake fluid while staying flexible enough to seal properly through temperature changes and years of use.
Installation Notes
When you’re doing brake work, always replace both the small and large O-rings together—they wear at the same rate and partial repairs usually lead to comeback problems. Take your time cleaning the piston bore and make sure there’s no debris or scoring that could cut the new O-ring.
