This brake pump is a hydraulic component that generates the fluid pressure required to actuate the braking system on the host tractor. It is located within the hydraulic system and draws fluid from the reservoir to supply the brake circuits. A failing pump typically results in a soft or unresponsive brake pedal, as the system cannot maintain the necessary line pressure. As an original-manufacturer part, the pump is built to the same displacement and port geometry as the original assembly, ensuring that the brake master cylinder receives the correct flow rate without requiring adapter fittings or line modifications.
