Description
When your brake pedal starts feeling spongy or you spot brake fluid under the tractor, there’s a good chance you’ve got a worn brake disc O-ring. 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 hydraulic seal that keeps your brakes working reliably when you need them most.
What You’re Getting
- Precision-molded O-ring designed specifically for John Deere brake disc applications
- Special compound that resists swelling from brake fluid while staying flexible
- Maintains proper hydraulic seal under high pressure during brake application
- Direct replacement – no modifications needed for proper fit
Built for Real Farm Work
This O-ring fits John Deere 5E, 5R, 6J, and 6R series tractors that handle everything from loader work around the farmyard to heavy field operations. Whether you’re running a compact utility tractor or a larger row-crop machine, dependable brakes are critical when hauling loads, working on slopes, or making quick stops around livestock and equipment.
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 across temperature extremes, from cold morning starts to hot brake conditions.
Installation Notes
Replace both brake disc O-rings as a set for best results, and always flush the brake system with clean fluid during installation. Watch for early warning signs: brake fluid on wheels or axles, dropping fluid levels, or that spongy brake pedal feel. Don’t wait for complete brake failure – catch the problem early and replace worn seals before they leave you in a dangerous situation.
