A tool for bleeding brakes includes a primary assembly, a quick-connect actuator assembly, and a nozzle fitting. The primary assembly has a hollow central shaft, a female quick-connect fitting, and a socket wrench at a distal end of the shaft. The quick-connect actuator assembly is in operates the female quick-connect fitting. The nozzle fitting is disposed at a proximal end of the central shaft, is in fluid communication with the socket wrench via the hollow central shaft, and is adapted to receive an end of a brake fluid waste line. The quick-connect fitting receives and retains the bleed screw such that the socket fits around a hex fitting on a bleed screw. The wrench loosens the bleed screw causing fluid to flow through the tool and out the nozzle fitting.

A method (purge procedure) for purging a decoupled brake system including: a brake fluid reservoir, a master cylinder, a brake circuit connected to the wheel brakes, a pump equipped with a plunger. A segment of the brake circuit to be purged is isolated by closing the solenoid valves at the extremities of the segment, a vacuum is created with the plunger, and an extremity of this segment is placed in communication with the exterior to evacuate the trapped air bubble.

A brake control system for a vehicle, the brake control system including a master cylinder, a brake line for communicating brake fluid between the master cylinder and a brake, a fluid reservoir in fluid communication with the brake line during non-braking conditions, and means for selectively moving brake fluid into and/or out of the fluid reservoir. The means for selectively moving brake fluid into and/or out of the fluid reservoir includes means for removing gas from the fluid reservoir, and is configured to move brake fluid into the fluid reservoir, so that brake fluid is moved along the brake line in a direction towards the master cylinder, during non-braking conditions. Upon receiving a signal of an anticipated brake event, brake fluid may also be moved out of the fluid reservoir, so that brake fluid is moved along the brake line in a direction away from the master cylinder.

An air bleeding apparatus and method for electric brake systems. The air bleeding apparatus includes a piston position sensor configured to detect a position of a piston installed in a main master cylinder, a motor drive unit configured to drive a motor to move the piston, a motor speed detection unit configured to detect a speed of rotation of the motor, a brake pedal position sensor configured to detect a position of a brake pedal, and a control unit configured to, when entering an air bleeding mode, release a normally actuated valve and control the position of the piston by controlling the motor drive unit according to the position of the piston detected by the piston position sensor or the speed of rotation of the motor detected by the motor speed detection unit when it is determined that the brake pedal is pressed.
