Description

When your brakes start feeling spongy or you notice brake fluid dripping under your tractor, there’s a good chance a worn brake piston O-ring is to blame. Don’t wait for brake failure on a loaded haul or steep grade – replace worn O-rings at the first sign of leakage. Brake fluid dripping from worn O-rings is more than an annoyance – it’s a safety hazard that gets worse with every use. This replacement O-ring restores the tight seal your hydraulic brake system needs to keep you stopping safely.

What You’re Getting

Precision-fit seal that stops brake fluid leaks and restores proper hydraulic pressure
Special brake fluid-resistant compounds that won’t swell or deteriorate from fluid exposure
Temperature-stable material that maintains flexibility from cold mornings to hot brake conditions
Direct replacement – no modifications needed for proper installation

Built for Real Farm Work

This O-ring fits an extensive range of John Deere tractors from the workhorse 6000 and 7000 series up through the big 8000 series track tractors. Whether you’re running a 6170R on hay operations, using a 7830 for heavy tillage, or operating an 8000 series track machine for large-scale farming, these tractors handle demanding work where dependable brakes are essential for safety.

Made to Last

Brake system O-rings face unique challenges – exposure to hygroscopic brake fluid, high pressure during brake application, and heat from heavy braking. This O-ring uses special compounds that resist swelling from brake fluid absorption while maintaining the flexibility needed for proper sealing. It’s built to handle the demanding conditions that come with farm work.

Good to Know

Watch for early warning signs: brake fluid on wheels or axles, dropping fluid levels, or that spongy brake pedal feel. Stock several in your parts bin – when you find one leaking O-ring, others are usually close behind. Replace both sides when doing brake work – it’s cheap insurance for reliable stopping power.
