Description

Brake fluid dripping from worn O-rings is more than an annoyance – it’s a safety hazard that gets worse with every use. When you’re hauling a loaded grain cart down a country road or working on slopes with heavy implements, the last thing you need is spongy brakes or fluid leaks compromising your stopping power. This brake piston O-ring seals the hydraulic brake system properly, keeping brake fluid where it belongs and ensuring reliable stops when you need them most.

What You’re Getting

Direct replacement O-ring that restores proper sealing in brake pistons
Quality rubber compound that resists brake fluid absorption and swelling
Maintains flexibility across temperature extremes, from cold morning starts to hot conditions
Handles the high pressure cycles of hydraulic brake applications

Built for Real Farm Work

This O-ring fits an extensive range of John Deere tractors from compact utility models up to row-crop workhorses. Whether you’re running a 1750 with a loader around the farmyard, pulling implements with a 5310, or hauling wagons with a 6420 during harvest, these machines depend on hydraulic brakes for safe operation. This O-ring maintains the hydraulic integrity that gives you consistent, powerful braking when you need it most – especially important when traveling on roads or working on slopes.

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. The material stays stable whether you’re starting up on a frosty morning or working through hot summer days with heavy braking.

Good to Know

Watch for early warning signs: brake fluid on wheels or axles, dropping fluid levels, or that spongy brake pedal feel. When you’re replacing one brake piston O-ring, it’s smart to inspect the others – they’ve all been working in the same conditions for the same amount of time. Stock several in your parts bin – when you find one leaking O-ring, others are usually close behind.
