However, the newest vehicle involved in the study was a 1986 model and no test vehicles were equipped with the electronic control (drive by wire) systems common in 2010. All vehicles were equipped with automatic transmissions , that is, no vehicles had manual transmissions with left foot clutch pedal disengagement of engine power.
As the S-cam rotates, the two symmetrical brake pads are forced against the brake drum until the pressure is released and the brake pads return to their resting position. [3] The principle of the S-cam allows the brakes of big vehicles to be more compact and less moving parts, since it only relies on a rotating shaft.
In contrast, for a brake without self-assist, such as a conventional disc brake, a loss of pad friction material does not change the pad force, so there is no necessary loss in the brake torque reaction for a given amount of input force. The self-assist mechanism affects the water pump and the amount of fade.
Over the years, EM became known as electromagnetic versus electro mechanical, referring more about their actuation method versus physical operation. Since the clutches started becoming popular over 60 years ago, the variety of applications and brake and clutch designs has increased dramatically, but the basic operation remains the same.
SpeedE, an academic concept car developed for studying drive-by-wire technologies such as brake-by-wire. Brake-by-wire technology in the automotive industry is the ability to control brakes through electronic means, without a mechanical connection that transfers force to the physical braking system from a driver input apparatus such as a pedal or lever.
A roller brake tester is a method of allowing the dynamic assessment of the braking system of a motor vehicle, whilst the vehicle itself is in a static condition.This type of brake tester is normally used in UK garages when used as part of an inspection lane for the MOT test.

Electromagnetic brakes or EM brakes are used to slow or stop vehicles using electromagnetic force to apply mechanical resistance (friction). They were originally called electro-mechanical brakes but over the years the name changed to "electromagnetic brakes", referring to their actuation method which is generally unrelated to modern electro-mechanical brakes.
