Vacuum boosters provide brake assist for the driver by multiplying the force out of the booster creating more than the force that was used to push on the brake pedal. The booster works by pulling the air out of the booster chamber with a pump or other vacuum source (typically the engine's intake manifold [1]), creating a low-pressure system ...
In the US it is commonly called a brake booster. A vacuum servo, also known as a power booster or power brake unit, uses a vacuum, usually supplied by the engine, to multiply the driver's pedal effort and apply that effort to the master cylinder .
The fault could be lack of hydraulic fluid, low brake fluid in the reservoir, a broken hydraulic line or a bad master brake cylinder. The sensor is used to detect pressure differentials in the hydraulic system. If the car alerts a fault in the hydraulic system and the system checks out, the sensor itself may have failed. [2]
The Department of Transportation reported in 2011 that the only causes for SUA were pedal misapplication and wrong mats. Most complaints came after the Toyota recall. The cars' event data recorders showed application of accelerator pedal and no application of brake pedal. [citation needed] NASA was unable to replicate engine control failure ...
Brake fade can be a factor in any vehicle that utilizes a friction braking system including automobiles, trucks, motorcycles, airplanes, and bicycles. Brake fade is caused by a buildup of heat in the braking surfaces and the subsequent changes and reactions in the brake system components and can be experienced with both drum brakes and disc ...

The vacuum booster or vacuum servo is used in most modern hydraulic brake systems which contain four wheels, the vacuum booster is attached between the master cylinder and the brake pedal and multiplies the braking force applied by the driver.
