Abstract
A diagnosing apparatus for diagnosing a pressurizing device provided in a hydraulically operated braking system operated by a brake operating member, wherein a hydraulic pressure detecting device is operable to detect a hydraulic pressure which is a sum of a first fluid pressure generated by an operation of the brake operating member, and a second fluid pressure generated by an operation of the pressurizing device, and a diagnosing device is operable to determine whether the pressurizing device is abnormal or not, on the basis of the hydraulic pressure detected while the brake operating member is not in operation and while the pressurizing device is in operation.
