The motor Vehicle 13th edition
Theory of Ground Vehicles
Two distinct demands are made upon the brakes of motor vehicles. First, in emergencies they must bring the vehicle to rest in the shortest possible distance, and secondly, they must enable control of the vehicle to be retained when descending long hills. The first demand calls for brakes which can
apply large braking torques to the brake drums, while the second calls for brakes that can dissipate large quantities of heat without large temperature rises. It may be pointed out that the same amount of energy has to be dissipated as heat when a car descends only 400 yards of a 1 : 30 incline, as when the same car is brought to rest from a speed of 35 mph. Thus heat dissipation hardly enters into the braking question when emergency stops are considered, but when descending long hills the problem is almost entirely one of heat dissipation. In present-day vehicles the wheel brakes are usually operated by a foot pedal and are the ones used on most occasions; they are sometimes referred
to as the service brakes. The brakes on the rear wheels can generally be operated also by a hand lever and are used chiefly for holding the vehicle when it is parked and are consequently called parking brakes but as they can, of course, be used in emergencies they are sometimes called emergency brakes.

The prime function of an antilock brake system is to prevent the tire from locking, and ideally to keep the skid of the tire within a desired range This will ensure that the tire can develop a sufficiently high braking force for stopping the vehicle, and at the same time it can retain an adequate cornering force for directional control and stability. Data collected in Germany and other countries in the mid-1980's have shown that the introduction of antilock brake systems has reduced a noticeable number of traffic accidents involving passenger cars, and has also mitigated the consequences of a number of accidents.
