Description
When your brake pedal feels spongy or your tractor keeps rolling after you’ve stopped, it’s likely the slave cylinder that’s calling it quits. These Ford brake systems use special LHM mineral oil that doesn’t absorb moisture like regular brake fluid, but when the slave cylinder seals start leaking, you’ll lose that smooth, responsive braking you depend on. This replacement gets your stopping power back to where it should be.
What You’re Getting
- Direct replacement slave cylinder that restores proper brake pressure and pedal feel
- Built for LHM mineral oil systems—no compatibility issues with your tractor’s special hydraulic setup
- Precision-machined components that handle the pressure cycles and harsh conditions of farm work
- Quality seals and construction that won’t quit when you’re hauling loads or working slopes
Built for Real Farm Work
Your Ford 40 series and TS series tractors are workhorses that handle everything from field cultivation and harvesting to hay production and livestock management. Whether you’re running a 60-horsepower utility tractor or pushing 115 HP through demanding field conditions, reliable brakes aren’t optional when you’re pulling loaded equipment or navigating challenging terrain.
Made to Last
Master and slave cylinders endure thousands of pressure cycles in demanding conditions, and this replacement features precision-machined components that maintain consistent brake feel without the fade or sponginess of worn units. The seals are specifically designed to work with LHM fluid’s unique properties, so they’ll keep doing their job season after season.
Good to Know
This system specifically requires LHM mineral oil, not standard brake fluid—using the wrong fluid destroys seals quickly and leads to rapid failure. Never mix fluids or use substitutes, and keep LHM mineral oil on hand for topping off and maintenance. The actuator for this system is part number 401101 if you need that component as well.
