Description
When your brake lights stop working or the trailer brakes won’t engage, it’s usually not the bulbs or wiring—it’s this little switch that tells everything downstream what’s happening. This brake switch sits in your hydraulic brake line and activates whenever you step on the pedal, keeping you legal on the road and making sure your equipment brakes work when you need them.
What You’re Getting
- Precise M16 x 1.5 threading for direct replacement on MF 300 series tractors
- Reliable switching action that handles the daily cycles of brake operation
- Quality electrical contacts that won’t corrode or fail in farm conditions
- Proper pressure rating for hydraulic brake systems—no leaks or failures
Built for Real Farm Work
This switch is designed specifically for Massey Ferguson 300 series tractors, the workhorses that handle everything from hay operations to loader work. Whether you’re pulling a loaded grain wagon down the road or backing up to a hay baler in the field, functioning brake lights aren’t just convenient—they’re required by law and essential for safety around other traffic and equipment.
Made to Last
Brake switches live in a tough neighborhood, dealing with brake fluid, vibration, and constant pressure changes. This replacement uses quality materials that resist corrosion and maintain proper electrical contact through thousands of brake applications. The threaded body seals properly in your brake line without the weeping that leads to air in the system.
Good to Know
Installation is straightforward—just thread it into the brake line where the old switch was located. Make sure you have some brake fluid handy to top off the system after installation, and bleed any air that might get in during the swap. Test your brake lights and trailer brake controller before heading out on the road.
