A braking system includes first pressure sensorswhich are provided to braking pipeswhich constitute first input-side pressure sensors for detecting a liquid pressure on a front-wheel-master-cylinder-side and a rear-wheel-master-cylinder-side, and second pressure sensorswhich are provided at positions closer to a stroke-simulator-side than second solenoid-operated valvesof braking pipeswhich constitute second input-side pressure sensors for detecting a liquid pressure on the stroke-simulator-side.

Braking system

A stroke simulator in a brake system includes a cylinder body, a piston movably inserted in the cylinder body, and a second elastic member adapted to be pressed by the piston. It functions to give a simulative operational feel to a brake lever by operating the brake lever to generate a fluid pressure in a front wheel master cylinder and transmit this fluid pressure to the cylinder body, thereby deforming the second elastic member through the piston, and wherein annular recesses are formed on the outer circumferential surface of the second elastic member.

Stroke simulator in brake system

A vehicle-use brake device for miniaturization of a base body and the simplification of brake liquid pressure passages formed in the base body. First electromagnetic open/close valves changing over communication/interruption between master cylinders which output liquid pressures due to the operation of brake operators and wheel brakes, and second electromagnetic open/close valves changing over communication/interruption between a liquid-pressure generation member which are configured to generate liquid pressures due to operations of electrically-operated actuators and the wheel brakes are arranged in the base body. An output port which is connected to a wheel brake is formed in one flat side surface of a base body, first and second electromagnetic open/close valves which arrange operational axes thereof on a first plane orthogonal to one side surface are mounted on one surface of the base body which orthogonally intersects with one side surface from the same direction.
