摘要： A hydraulic brake master cylinder assembly includes a central or center port compensation valve mounted in respective brake actuator pistons and having a variable length stem which may be adjusted to predetermine the amount of valve travel between open and closed positions in response to actuation of the brake cylinder piston or pistons. The variable length stem includes a hub and a sleeve which is force fit over the hub and may be moved to set the length of the stem. The amount of gap or open position of the valve in the primary piston may be determined by installing the primary piston in the master cylinder, holding the piston in a fixed position and installing a seal retainer and washer for engaging the primary piston pin to move the pin to set the length of the valve stem.

摘要： A hydraulic brake master cylinder for a vehicle includes a pressure transducer mounted in the master cylinder primary piston for sensing hydraulic pressure applied to a brake circuit. Transducer signals are transmitted to the exterior of the master cylinder housing through terminals on the transducer which are connected to a plug member mounted on the end of the brake piston actuator rod. The plug member and the rod include passages for extending conductors therethrough for transmitting the transducer signals from the master cylinder.

摘要： A brake master cylinder-sensor system and method are provided. The system includes a master cylinder, a piston slidably positioned in the master cylinder, a magnet positioned on the piston, and a sensor disposed on the master cylinder. A change of piston linear position causes a linear change in a magnetic field position sensed by the sensor, and a brake control signal proportional to the change of piston linear position is generated. A method of operating a brake master cylinder-sensor system includes applying a brake pedal force, changing a piston linear position within a master cylinder, determining a change in a linear magnetic field position proportional to the change of the piston linear position, and generating a brake control signal based on the change in the linear magnetic field position.
