Abstract:
1. A brake system comprising: a master cylinder that generates brake fluid pressure by a driver's braking operation; a first wheel cylinder that is provided on one of a front wheel and a rear wheel and can brake the wheel; a second wheel cylinder that is provided on the other of the front wheel and the rear wheel and can brake the wheel; a first fluid passage that provides a connection between the master cylinder and the first wheel cylinder; a first cut-off valve provided in the first fluid passage; a first brake fluid pressure generating device provided in the first fluid passage on the first wheel cylinder side relative to the first cut-off valve; a second fluid passage that branches off from the first fluid passage at a location between the first cut-off valve and the first brake fluid pressure generating device and communicates with a reservoir; a second cut-off valve provided in the second fluid passage; a cut-off member that cuts off communication between the first wheel cylinder and the reservoir when the first brake fluid pressure generating device operates; and a third fluid passage that permits the second wheel cylinder to communicate with a passage between the cut-off member and the second cut-off valve.
