摘要： A method for determining a leakage in a hydraulic brake system in a vehicle includes evaluating a suspected leakage in the hydraulic brake system and taking into account an actuation of an automated hand brake during the evaluation of the suspected leakage. The hydraulic brake system has a hydraulic footbrake and the automated hand brake has an electromechanical actuator. The hydraulic footbrake and the automated hand brake are configured to act on the same brake piston.

摘要： In a brake control system (10), a reservoir switch (60) detects a decrease in the amount of hydraulic fluid in a reservoir tank (26). An ECU (100) switches a master cutoff valve (22), a pressure increase valve (40), and a pressure decrease valve (42) and the like between open and closed. When a decrease in the amount of hydraulic fluid in the reservoir tank (26) is detected, the ECU (100) opens the master cutoff valve (22) to supply hydraulic fluid from a right front-wheel wheel cylinder (20FR) and a left front-wheel wheel cylinder (20FL) to a master cylinder (14), when release of a brake pedal (12) is detected.

摘要： A brake fluid reservoir (10) for a vehicle hydraulic brake system has a filler neck (16), a lid (18) which closes the filler neck, and a device for pressure compensation between the reservoir interior and the ambient atmosphere. In order, when the brake fluid reservoir (10) is in a steeply inclined position, to prevent an escape of brake fluid, in the lid (18) a first brake fluid forced-flow channel (32) is formed, which has an inlet (34) at the inside of the lid and an outlet (36) towards the outside of the lid. The forced-flow channel (32) extends between the inlet (34) and the outlet (36) along a curved path, which in relation to a plan view of the lid (18) runs through at least two quadrants.

摘要： A master cylinder (12) having a switch (70) which is activated by either a magnet (78) carried by a float (76) in a reservoir (40) or a pin (66) moved by a differential area piston (52). The switch (70) had a first blade (82) connected a source of electrical current (106) through an indicator light (124) and a second blade (88) connected to an electrical ground (114). A reed switch (100) is connected to the first (82) and second (88) blades and responds to the magnet to close an electrical circuit to operate the indicator light (124) if a low fluid level is present in the reservoir (40). A first contact (96) on the first blade (82) is positioned in switch 70 by a non-electrical conductive actuation pin (66) that extends through the housing (22) of the master cylinder (12). A second contact (94) on the second blade ( 88) has a projection (92) that engages the housing (22) of the master cylinder (12) to define a fixed location for the first contact (94) and establish a fixed gap between the first (94) and second (96) contacts. If a pressure differential is created in the master cylinder (12) between the fluid pressure supplied to operate the wheel brakes (18) and (20), the differential area piston (52) moves and brings the second contact (96) into engagement with the first contact (94) to close the electrical circuit and activate the indicator light (124).
