A control unit affixed to an adjustable stand mounted on a platform on wheels, has an electrical on/off switch which controls the vacuum pump of the extractor unit, a brake fluid and air extractor control valve which controls the flow of air and brake fluid being extracted from the master cylinder and brake system, a brake fluid application control valve which controls the flow of brake fluid (free of air) from the brake fluid reservoir container (with bracket) affixed on top of the control unit, a vacuum meter indicator which indicates the amount of vacuum present, and a master cylinder brake reservoir top with U-bolt which fit securely over the master cylinder of an automobile or truck. The control unit is connected to the master cylinder brake reservoir top by a heavy duty dual function extractor/application hose. The master cylinder brake reservoir top can be modified to fit other motor vehicles. An extractor unit mounted on a platform with wheels, has a vacuum pump which creates a suction action for pulling brake fluid and air out of the brake system, an extractor brake fluid collection container (with holes to reduce pressure) with bracket to hold the collection container, a junction box for electrical connections, a heavy duty extraction hose which connects the extractor unit to the control unit, and a collection hose which connects the collection container to the vacuum pump.
