BRAKE DEVICE

摘要

A brake device includes an electric brake mechanism that applies electric braking force, a hydraulic brake mechanism that applies hydraulic braking force, an electric brake ECU (40) that directs the electric brake mechanism to generate the electric braking force according to an operation amount of a brake pedal (86) operated by a driver, a master cylinder (48) in which a volume thereof changes according to the operation amount of the brake pedal (86), and that is able to deliver operating fluid (90) to the hydraulic brake mechanism (46) by a reduction in the volume, and a reservoir (92) that stores the operating fluid (90). The master cylinder (48) has a discharge port (94) that discharges the operating fluid (90) that is inside of the master cylinder (48) to the reservoir (92).
