Abstract:
In this report a comparison of three Braking systems; Calliper, Drum and Disc will be made on a variety of areas including – * * Effectiveness * Performance * Features * Materials * Frictional Components * Difference from comparable car systems

An Orthogonal and Pictorial drawing will also be provided on a selected section of one of the braking systems being compared.

Introduction:
Bicycle Braking systems are a means of which we are able to halt the movement of a bicycle through the expulsion of kinetic energy. The Kinetic potential energy that is present in a moving bicycle is

The typical Disc Brake system is a very adaptable structure as it can perform better than Calliper Brakes in the mud, rain and snow as the coefficient of friction isn’t as at risk of contaminants disturbing the system. Disc brakes are also less prone to brake fading when subject to long periods of braking pressure, as they are very good at cooling down compared to drum and calliper brakes. A disk brake is also less likely to cause a popped tyre, with the heat not being dissipated directly into the tyre as in calliper brakes.

Calliper Brakes are generally the most common of the braking system for the everyday bicycle. Excluding the original design quality of the equipment and materials, calliper brakes are often affected mostly by the moisture that is on the rim, as that will significantly hinder the ability to stop. Tyre thickness can also pose a problem to the calliper braking system, as the arms will be under greater flexion, thus lessening brake effectiveness.
However, the Calliper brake system is effective on the average road bike and is the simplest and easiest to perform maintenance on of all three designs. This system also has a very big ‘mechanical advantage’, meaning very little effort has to be put in by the rider in order to properly apply the brakes.
Calliper brakes are also
