The braking system contains many moving parts, and because brakes work by creating friction to slow or stop the vehicle, many of these parts wear a little each time the brakes are applied.

Problems with your brakes?

For example, brake pads contain 'friction material' – a material with a rough surface which is forced onto the brake disc to slow it down, or stop it completely, during braking. This rate that this friction material wears is dependent on many factors, including whether you do more 'stop-start' town driving or motorway miles, where the brakes have to slow or stop the vehicle from higher speeds. Driving style is another factor.

Your brakes will usually wear gradually so you might not notice a sudden difference, however there are a few ways in which you can tell that your brakes should be checked:
