Brake Assignment
Historical development of vehicle brakes:
The development of braking systems was synonymous with the invention of the wheel. It is assumed that some primitive methods of slowing and stoping the first vehicles and carts was to deploy a log attached by rope off the vehicle and allow it to drag along behind. Another assumed method may have been to deploy an anchor of wedge that could be stuck into the ground. As the development of brakes was becoming more of an important issue, the dragged systems adapted into onboard more efficient devices such as a wedge to jam against one wheel causing a skid. Although this method was easier and more efficient, it was also quite dangerous as the vehicle would often turn and in some cases cause it to overturn.
The first effective braking system was introduced in 1838, the spoon brake. This system consisted of a wooden block that pressed against the iron wheel of the vehicle when a lever of foot pedal was mechanically applied by the operator. On heavier vehicles another adaptation of this brake was used where the friction block of the spoon brake was applied to one of the pullies in the transmission.
The next developed braking system invented was the external contracting band brake. This system was largely more effective than the spoon brake. The band brake consisted of a drum attached to the axle of the rear wheels or the drive shaft under the vehicle, that was accompanied by a band with a friction lining that wrapped around the drum and was applied by a hand lever that acted on a number of solid rods that pulled and in turn contracted the band around the drum. This system became popular and widely used by manufactures by 1904.
In 1898 the early disc brake was developed, these brakes made a large amount of noise and were highly inefficient, and as a result soon forgotten. In there replacement was the invention of the drum brake or the internally expanding shoe brake. This development was considered to be the most effective
