Brakes are a highly important part of any vehicle and are what allow you to stay in control of your car – slowing down the speed and completely bringing it to a halt when necessary. We are all highly indebted to brakes then, but few of us know how they work. Here we will look briefly at the mechanism of most car brakes.
Most cars use what is called a 'drum brake' and this name reflects the fact that the brake mechanism utilises a 'drum' which is a spinning metal part of the wheel. This drum provides a metal edge onto which brake pads or another mechanism which 'squeeze' the drum and thereby provide friction, gradually slowing down the wheel and eventually bringing it to a complete halt.
To better visualise how brake parts work, you can visualise the brakes on a push bike. These have brake pads that work in the same way and squeeze the tire to slow it down. Brake parts in a car work in just the same way, except the brake pads grip onto a brake drum instead which is not visible from the exterior of the car.
