Description

When you’ve got an older MF 300 series tractor that’s been your workhorse for years, keeping that brake system working right is no joke. This early type brake master cylinder tube is what connects your pedal to the stopping power—and when it starts leaking or gets plugged up, you’ll know it real quick. Whether you’re hauling grain wagons down steep hills or making tight turns in the farmyard, you need brakes that respond when you push that pedal.

Key Features

Early type design specifically for pre-1987 MF 300 series tractors that use external brake slave cylinders
Direct replacement tube that routes brake fluid from the master cylinder to the brake system components
Built to handle the pressure and vibration that comes with decades of farm work
Quality materials resist corrosion from brake fluid and weather exposure
Proper fit means no modifications or adapters needed—just like the original

Built for Real Farm Work

Your early 300 series MF tractor was built when these machines were designed to last generations, not just seasons. These tractors handle everything from loader work around the barn to pulling heavy implements across rolling fields. The brake system on these early models uses a different setup than the later tractors—external slave cylinders instead of the internal ones—so getting the right tube matters for safety and performance.

Made to Last

Farm brake lines take serious abuse from vibration, weather, and the constant flexing that comes with hydraulic pressure. This tube is engineered to handle the specific demands of your MF brake system, with materials that won’t deteriorate from brake fluid exposure or crack from temperature changes. It’s built to maintain that solid connection between your master cylinder and the rest of the brake system.

Good to Know

When replacing brake tubes, it’s smart to flush your brake fluid at the same time—fresh fluid helps protect all the seals and components. Make sure you’re using the right brake fluid for your early 300 series system, and always bleed the brakes properly after installation. If you’re doing this work yourself, take your time with the fittings—cross-threaded brake lines cause bigger problems down the road.
