An agricultural tractor brake pressure disc is a component of the braking system in a tractor that helps to slow down or stop the vehicle. It is a circular disc made of high-strength materials such as steel or ceramic, and is located inside the brake caliper. When the brake pedal is pressed, hydraulic pressure is applied to the brake disc, causing it to clamp down on the brake rotor or drum, which in turn slows down or stops the tractor. The pressure disc is designed to withstand high temperatures and friction, and is an essential safety feature in agricultural tractors.
