Abstract: A vehicle braking system master cylinder that can handle pressure pulses within the brake fluid of a vehicle braking system without the destruction of components internal to a master cylinder. A vehicle braking system master cylinder that allows for component subassembly external to the master cylinder and is self-aligning when assembled. Finally, a vehicle braking system master cylinder that allows for variable travel of the primary piston and the secondary piston within the master cylinder and greater fluid flow in the vehicle braking system.

Abstract: 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.
