Patent ID: 8496301

Claim:
A vehicle brake mechanism comprising: a master cylinder operated with a brake pedal and having a first hydraulic chamber and a second hydraulic chamber, the master cylinder being capable of generating hydraulic pressures for two circuits; a stroke simulator that is provided between the brake pedal and the master cylinder and that is elastically deformable by a treading force applied to the brake pedal; a first fluid channel connecting the first hydraulic chamber of the master cylinder to a first-circuit wheel cylinder; a second fluid channel connecting the second hydraulic chamber of the master cylinder to a second-circuit wheel cylinder; a master cut valve that is provided in the first fluid channel and that is capable of hindering communication between the first hydraulic chamber and the first-circuit wheel cylinder; a slave cylinder connected to the second fluid channel and driven by an actuator to generate a hydraulic pressure; a third fluid channel provided downstream of the master cut valve and the slave cylinder and connecting the first fluid channel and the second fluid channel to each other; and a connection control valve provided in the third fluid channel to close the third fluid channel.
