Description

When your brake pedal starts feeling spongy or you’re pushing it further than usual before anything happens, it’s time to look at your master cylinder. A failing master cylinder doesn’t just make stopping harder—it can leave you without brakes when you need them most, whether you’re hauling a loaded wagon down a hill or trying to make a quick stop around livestock. This replacement master cylinder restores that firm, responsive pedal feel that lets you work with confidence.

What You’re Getting

22.2mm bore diameter that matches your original equipment for proper brake fluid pressure
Heavy-duty cast iron construction that stands up to years of field work and temperature swings
Precision-machined cylinder walls that keep your brake fluid flowing smoothly without leaks
Complete assembly ready to install with all the mounting points you need
Built to the same specs as your original Deutz master cylinder

Built for Real Farm Work

This master cylinder fits a wide range of Deutz tractors from the compact DX3 utility models up through the bigger DX6 row-crop machines. Whether you’re running a loader tractor around the farmyard, pulling implements across rolling fields, or hauling grain to the elevator, these are versatile machines that need reliable braking for safe operation in all kinds of conditions.

Made to Last

Brake master cylinders take serious abuse on farm tractors—they’re constantly exposed to vibration, temperature extremes, and the demanding stop-and-go nature of field work. This unit features robust seals that resist brake fluid breakdown and maintain their grip even after thousands of pressure cycles. The precision-bored cylinder keeps brake pressure consistent to all wheels, preventing that dangerous pull to one side.

Installation Notes

This is a direct replacement that mounts in the original location using your existing brake lines. Make sure you have fresh brake fluid on hand—it’s the perfect time to flush the whole system. Remember to bleed the system thoroughly after installation, starting with the wheel furthest from the master cylinder and working your way closer. If you’re also dealing with brake issues at the wheels, take a look at the matching slave cylinder repair kit 53921.
