Brake system for motorcycle

摘要

Problem: To prevent the power consumption from increasing in a motorcycle brake system which enables smooth switching to a hydraulic loss simulator to provide an improved feeling of braking operation. Solution: A motorcycle brake system includes a brake operating unit (2), a brake caliper (4), an electromagnetic on-off valve (V1) which blocks a main brake passage (5), a pressure sensor (28), a hydraulic modulator (6), and a hydraulic loss simulator (9), the motorcycle brake system allocating a braking force to front and rear wheels by controlling the hydraulic modulator (6) based on a result of detection by the pressure sensor (28). The brake operating unit (2) has a brake light switch (32) for detecting starting of operation thereof, actuates an electromagnetic on-off valve (V1) to block the main brake passage (5) based on a result of detection by the brake light switch (32), and unblocks the main brake passage (5) when a predetermined amount of time elapses without any input made to the pressure sensor (28) in a standby state with the main brake passage (5) blocked.
