Description
When that brake pedal starts feeling spongy or you notice brake fluid spots under your tractor, it’s usually a worn O-ring letting precious hydraulic pressure escape. This brake piston O-ring restores the tight seal that keeps your Case IH stopping power where it belongs – in the brake system, not on the shop floor.
What You’re Getting
- Precision-molded rubber that handles high brake pressures without failing
- Special compound designed for brake fluid compatibility and temperature extremes
- 10-inch by 1/8-inch size specifically for Case IH brake piston applications
- Direct replacement that fits like the original factory seal
Built for Real Farm Work
This O-ring fits across multiple Case IH tractor families from the reliable 84 series through the versatile 85 and 95 series tractors. Whether your 684 is running a discbine, your 785 XL is pulling wagons during harvest, or that 885 is handling loader duties around the farmyard, dependable brakes are essential for safe operation on slopes and during road travel.
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 from cold morning starts to hot summer work.
Installation Notes
Replacing this O-ring means getting into the brake system, so it’s a good time to check the entire setup for other worn components. Always bleed the brakes properly after installation – any air in the system will give you that spongy pedal feel you’re trying to eliminate. Watch for early warning signs: brake fluid on wheels or axles, dropping fluid levels, or that spongy brake pedal feel.
