Brakes

Until the 1930s, most systems for stopping vehicles were mechanically actuated drum brakes with internally expanding shoes; i.e., foot pressure exerted on the brake pedal was carried directly to semicircular brake shoes by a system of flexible cables. Mechanical brakes, however, were difficult to keep adjusted so that equal braking force was applied at each wheel; and, as vehicle weights and speeds increased, more and more effort on the brake pedal was demanded of the driver.

Mechanical brakes were replaced by hydraulic systems, in which the brake pedal is connected to pistons in master cylinders and thence by steel tubing with flexible sections to individual cylinders at the wheels. Front and rear hydraulic circuits are separated. The wheel cylinders are located between the movable ends of the brake shoes, and each is fitted with two pistons. As these pistons move outward, they push the brake shoes against the inner surface of the brake drum attached to the wheel.

Further increases in vehicle weights and speeds in the 1950s made even hydraulic brakes difficult for drivers to operate effectively, and automobiles were equipped with power brake systems. These are virtually the same as the hydraulic system except that the piston of the master cylinder is operated by a vacuum piston and cylinder instead of by the pressure exerted on the brake pedal.

Disc brakes, originally developed for aircraft, have become increasingly popular because of their fade resistance. Although there are some four-wheel systems, usually discs are mounted on the front wheels.

Antilock braking systems (ABS) were available in the late 1980s and became standard equipment on a growing number of passenger cars. ABS installations consist of wheel-mounted sensors that input wheel rotation speed into a microprocessor.
