Description
When you’re working long hours with heavy loads or need to stop quickly at the end of a row, your brakes better work right the first time. A failing master cylinder can leave you with a spongy pedal or no brakes at all—not something you want to discover when hauling grain or working near ditches. This servo hydraulic brake master cylinder restores that firm, responsive pedal feel you need to work confidently with your Maxxum MX tractor.
What You’re Getting
- Servo hydraulic design that multiplies your pedal force for more stopping power with less effort
- Precision-machined bore that maintains consistent brake pressure to all wheels
- Heavy-duty internal seals that resist breakdown from constant pressure cycles and temperature swings
- Direct replacement unit that bolts right into your original mounting location
Built for Real Farm Work
These Maxxum MX tractors—from the 100-horsepower MX100 up to the 135-horsepower MX135—are workhorses that handle everything from loader work to heavy transport duties. Whether you’re pulling loaded implements through the field, backing up to grain carts, or making tight turns with a disc, you need brakes that respond instantly and consistently. The servo hydraulic system gives you more stopping force than standard hydraulic setups, which matters when you’re working with heavy equipment.
Made to Last
Farm brake systems take serious abuse from dust, temperature extremes, and constant use. This master cylinder features robust seals that won’t deteriorate from brake fluid exposure or the pressure cycles that come with daily farm work. The precision-machined cylinder bore ensures smooth operation and prevents that dangerous pull to one side that worn cylinders can cause.
Good to Know
This is a direct replacement that uses your existing brake lines and mounting hardware. Plan to have fresh brake fluid on hand—it’s the perfect time to flush the entire system. Make sure to bench-bleed the new cylinder before installation to prevent air pockets, and always bleed the system starting with the wheel furthest from the master cylinder.
