Abstract: The invention relates to a master brake cylinder arrangement with actuation detection for a motor vehicle braking system, having at least one piston arrangement with a piston, which is movably guided in a cylinder bore in a cylinder housing, said piston with the cylinder bore defining a pressure chamber which is fluidically coupled to a hydraulic brake circuit. During a forward stroke, the piston can be moved from a start position into a possible actuation piston along a movement axis, which coincides essentially with a longitudinal axis of the cylinder bore, and during a return stroke, said piston is moved from an actuation position into a start position. The piston is associated with a coupling element which is coupled to a position detecting rod for common movement therewith, said position detecting rod being moved essentially parallel to the first cylinder bore, the position of the position detecting rod can be detected by means of a position detecting sensor placed on the cylinder housing. According to the invention, in order to save space, the coupling element can be locked relative to the piston for a common lift movement therewith and after exceeding a predetermined path of the lift movement, the piston can be moved further relative to the coupling element.

Abstract: A primary piston composed of a skirt and an intermediate back wall having a rear face receiving the servobrake thrust rod and a forward face for the telescoping rod and the spring pushing the secondary piston. The front of the skirt has longitudinal grooves open in front and closed in the rear. The thickness of the skirt beneath the grooves and the part of the skirt between two successive grooves in the peripheral direction form a front face enabling the principal piston to push the secondary piston. The principal piston is made of a single piece of plastic material.

Abstract: In a hydraulic brake system including a cylinder device that includes a front chamber and a rear chamber located on front and rear sides of a pressurizing piston, respectively, presence or absence of liquid leakage from a brake line is detected based on a hydraulic pressure in the rear chamber. Where a state in which a subtraction value obtained by subtracting an actual rear hydraulic pressure from a target rear hydraulic pressure is larger than a first malfunction determination threshold value has continued for a time not shorter than a first malfunction determination time, and then an increase of the actual rear hydraulic pressure at a rate not lower than a set rate has caused the subtraction value to become smaller than a return determination threshold value, it is determined that the pressurizing piston has been bottomed due to liquid leakage from the front chamber.
