Description

When you’re hauling heavy grain carts down county roads or working steep hillsides with a big tractor, you need brakes that respond the instant you press the pedal. A worn or warped brake disc can cause that heart-stopping moment when you push the pedal and nothing happens like it should. This 427mm brake disc restores the stopping power your John Deere was built to deliver, giving you the confidence to work safely no matter what the terrain throws at you.

What You’re Getting

Precision-machined 427mm diameter disc that matches OEM specifications exactly
Heat-treated construction that resists warping from repeated heavy braking
Smooth, consistent surface for even pad contact and reliable stopping power
Direct replacement design that installs with standard brake tools
Built to handle the demands of large agricultural tractors

Built for Real Farm Work

This disc fits John Deere’s heavy-duty tractor lineup including the 7R, 8R, and 9R series along with the proven 8000, 9000, 8010, 8030, 9020, and 9030 series machines. Whether you’re running a 7R on row crop duty, pulling heavy implements with an 8R, or handling the biggest jobs with a 9R series four-wheel drive, these are tractors that demand reliable braking for both field work and road transport.

Made to Last

Large tractors generate serious heat when braking, especially when loaded down with heavy implements or grain. This disc is engineered to dissipate that heat effectively while maintaining its flatness and finish. The quality metallurgy prevents cracking and premature wear, ensuring consistent brake performance through thousands of hours of operation.

Good to Know

Always replace brake pads when installing a new disc – fresh pads on a new disc surface give you the best braking performance and longest life. Check that the disc mounts flat against the hub with no runout before tightening the bolts. If you’re doing the work yourself, a dial indicator helps verify everything’s running true.
