This brake pump repair kit contains the seals, gaskets, and internal components needed to restore the brake pump to its original operating condition. It sits within the brake system of the host tractor, where the pump generates hydraulic pressure to actuate the brake calipers at each wheel. A failing pump, indicated by a soft pedal or reduced braking force, typically results from worn internal seals that allow fluid to bypass the piston. Using the manufacturer's original kit ensures the replacement elastomers match the original compound and cross-section, which is necessary for the pump to maintain its designed pressure curve and prevent internal leakage. On reinstall, clean the pump bore thoroughly and lubricate the new seals with clean brake fluid before assembly.
