This brake disc is a replacement component for the braking system of agricultural tractors. It is mounted on the axle shaft and interfaces with the caliper assembly to convert kinetic energy into heat through friction, slowing or stopping the wheel. A worn disc reduces braking force and can cause uneven pad wear, leading to longer stopping distances and potential safety hazards. The disc is manufactured to match the original geometry, including the tooth profile that engages with the drive hub, so no modification is required during installation. When replacing, clean the hub surface and torque the retaining hardware to the specified value.
