Vehicle braking device

摘要

The aim is to reliably detect abnormality of a brake device with a simple structure without providing a special detecting means. A pump for generating brake hydraulic pressure of a hydraulic brake device is driven when the ignition switch for starting the vehicle is closed. The rise time of the output of a brake hydraulic pressure detecting means provided in the hydraulic brake device is detected, and it is determined that uneven wear of the pads has occurred if the rise time is longer than a predetermined time. An alarm lamp is turned on to notify abnormality. Thereby it is possible to accurately detect abnormality of the brake device before the driver drives the vehicle without providing a special detecting means.
