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 backing music for the song was recorded using a group of Los Angeles session musicians nicknamed "The Wrecking Crew."The arrangement is credited to Harold Battiste, but Wrecking Crew bassist Carol Kaye asserts that at the session she devised the distinctive syncopated bass line that is featured on the released recording, replacing the original walking bass line in the prepared arrangement:
A compression release engine brake, compression brake, or decompression brake is an engine braking mechanism installed on some diesel engines. When activated, it opens exhaust valves to the cylinders, right before the compression stroke ends, releasing the compressed gas trapped in the cylinders, and slowing the vehicle.
The concept of brake pads or disc brakes as an alternative to drum brakes had been around at least as early as a patent by F. W. Lanchester in 1902. [2] However, due to high cost and inefficiencies compared to drum brakes they were not commonly implemented until after World War II. [3]

Regenerative and friction braking must both be used, creating the need to control them to produce the required total braking. The GM EV-1 was the first commercial car to do this. In 1997 and 1998, engineers Abraham Farag and Loren Majersik were issued two patents for this brake-by-wire technology. [3] [4]
