Description
Nothing’s more frustrating than spongy brakes when you’re backing up to a hay wagon or coming down a steep grade with a loaded trailer. When your brake pedal feels mushy or you have to pump it twice to get stopping power, chances are good your brake slave cylinder seal has given up. This LHM mineral oil-compatible seal gets your brakes back to that firm, confident feel you need for safe farm work.
What You’re Getting
- Precision-molded seal designed specifically for LHM mineral oil brake systems
- Direct replacement that restores proper hydraulic pressure in your brake slave cylinder
- High-quality rubber compound that resists heat, chemicals, and the constant pressure cycles of farm work
- OEM-specification materials ensuring the exact fit and performance as your original seal
Built for Real Farm Work
This seal fits Ford 40 series tractors (5640, 6640, 7740, 8240, 8340) and TS series models (TS90, TS100, TS110, TS115). These versatile tractors handle everything from hay cutting and loader work to grain hauling and heavy transport duties. When you’re working steep ground, navigating busy roads, or managing heavy implements, reliable brakes aren’t just convenient—they’re essential for safety.
Made to Last
Unlike standard brake seals that use DOT fluid, this seal is engineered specifically for LHM mineral oil systems. The special rubber formulation prevents the seal degradation and swelling that happens when you use the wrong type of seal. It maintains its flexibility through temperature swings and resists breakdown from exposure to hydraulic fluid and farm chemicals.
Installation Notes
Remember, this system requires LHM mineral oil only—never mix with regular brake fluid or you’ll damage the seals. While you’re replacing the slave cylinder seal, it’s a good time to check your brake master cylinder too, since they often wear together. Have plenty of rags ready during installation, as LHM fluid can stain concrete.
