In much the same way that vacuum boosters work, hydraulic power brake boosters rely on a pressure differential to provide braking assistance. The main difference is that it is hydraulic pressure that does the work rather than a vacuum-actuated servo.
Hydraulic disc brakes are the most commonly used form of brake for motor vehicles but the principles of a disc brake are applicable to almost any rotating shaft. Compared to drum brakes, disc brakes offer better stopping performance because the disc is more readily cooled. As a consequence discs are less prone to the brake fade caused when brake components overheat. Disc brakes also recover more quickly from immersion (wet brakes are less effective than dry ones).
