Apparatus and method for removing and replacing vehicle hydraulic fluid

摘要

An apparatus and method for removing, flushing contaminants from and replacing vehicle brake fluid. The apparatus has storage tanks for fresh and waste hydraulic fluid, a fill pump to pump hydraulic fresh hydraulic fluid to the vehicle braking system, an adapter for sealably connecting a fill hose to the master cylinder, a suction pump to suction used hydraulic fluid from the vehicle braking system to the waste fluid tank, a suction hose for suctioning fluid out of the master cylinder and hoses for connecting the waste fluid tank to the bleeder valves located at the vehicle wheels. A by-pass valve is provided between the fill pump and master cylinder to by-pass fluid when the fill hose reaches or exceeds a predetermined level. A computer and ancillary electrical and fluid connections between the various parts of the apparatus and the hydraulic fluid system of a vehicle are also utilized. The apparatus can also be used when replacing the master cylinder or when replacing fluid in other hydraulic systems (i.e. hydraulic clutch).
