A vacuum activated brake reservoir refilling apparatus and a vacuum activated brake fluid recovery apparatus. The invention utilizes vacuum created during the normal brake bleeding procedure and includes a holding container filled containing fresh brake fluid and an adjustable fluid distribution attachment which is clamped to a vehicle reservoir. An unobstructed path connects the bleeder valve to be bled and a fluid collection container. Both containers utilize check valves. The holding container can only valve air into its chamber, and the collection container can only valve air out of its chamber during the brake bleeding process.

A portable brake bleeder apparatus, for changing brake fluid in brake systems of vehicles using a hydraulic brake activated by pressure on and release of the brake pedal, brake fluid and having a brake fluid reservoir, brake lines and bleeder valves, the apparatus comprising: a holding container for the fresh brake fluid; an adjustable fluid distribution device adapted to sealingly clamp to the brake fluid reservoir; a first tubing section sealingly interconnecting said holding container and the fluid distribution device; a fluid collection container; a second tubing section sealingly interconnecting the collection container and one of said bleeder valves; a means for maintaining lowered pressure in the collection container, said lowered pressured created by pressure on the vehicle brake pedal, to draw new brake fluid from the holding container into the brake system, to force used brake fluid and contaminants out of the bleeder valve, and to prevent backflow of used brake fluid into the bleeder valve; said distributing device having a plurality of distribution ports adapted for sealing attachment to variously sized master cylinder brake reservoirs for fluid flow from said distribution device into said reservoir; wherein said means for maintaining lowered pressure comprises a one-way check valve associated with the holding container for input of air only to said holding container and a one-way check valve in said collection container for output of air only from said collection container, such that as brake pressure forces air from, and lowers pressure in, the collection container, backflow of used brake fluid from the collection container into the bleeder valve is prevented.
