This master cylinder ensures your brakes work the same whether you're empty or loaded. Made to Last Farm tractors beat up brake systems with constant use, temperature swings, and vibration. This master cylinder uses quality seals designed specifically for DOT brake fluid, so they won't deteriorate from heat or chemical exposure.

Good to Know Before installation, clean the mounting area and check your brake lines for damage or corrosion. Bench bleed the new cylinder to remove air—it saves time and headaches later. Always use fresh brake fluid from a sealed container, and bleed the entire system starting with the wheel farthest from the master cylinder. Never mix DOT fluid with mineral oil systems.
