Description

When you’re working steep ground or need to stop quickly with a heavy implement attached, reliable brakes aren’t just convenient—they’re what keep you and your equipment safe. Worn brake discs can mean longer stopping distances, grabbing or uneven braking, and that nervous feeling when you’re coming down a hill with a loaded manure spreader. These replacement brake discs get your stopping power back to where it should be.

What You’re Getting

Heavy-duty friction material that grips consistently whether you’re dry, dusty, or dealing with morning dew
305mm diameter x 70.5mm width with 15-spline configuration matches original factory specs exactly
10mm thickness provides the proper clearance and heat dissipation your brake system needs
Sold as a set so you can replace both sides at once for balanced braking performance
Direct replacement—no modifications or adapters needed to get them installed

Built for Real Farm Work

These discs fit the workhorse John Deere tractors that built American agriculture from the late ’70s through the ’90s. Whether you’re running a 2040 for general farm work, a 3140 for row crop farming, or a bigger 3650 for heavy field operations, these are the same quality discs that came on your tractor from the factory. They’re designed to handle the stop-and-go nature of farm work, from field to barn to road transport.

Made to Last

Farm brakes take a beating with dust, moisture, heavy loads, and constant temperature changes. These discs are built with quality friction material that resists glazing and provides consistent stopping power season after season. The precision-machined surface ensures smooth, even contact with your brake pads for reliable performance when you need it most.

Good to Know

Always replace brake discs in pairs to keep your braking balanced and safe. This job requires pulling the brake housing apart, so it’s a good time to check your brake pads, seals, and fluid while you’re in there. Make sure to verify your serial number is below 668664 before ordering—later tractors use a different part. Professional installation is recommended for safety-critical brake work.
