How to Spot Failing Brakes
The problem with brake failure is that it can be hard to diagnose. Wear and tear on brake discs and pads can’t always be seen very easily, but there are other ways to diagnose issues.
Commonly you’ll find two types of brake systems:
a) Disc Brakes &
b) Drum Brakes.
Disc brakes are often found on modern cars’ front wheels and are made up of a shiny disc behind the wheel, and a gripping clamp known as a brake caliper, which includes brake pads. Pads are made of a hard wearing material that presses against the brake disc, slowing it down using friction.
Drum brakes are fitted within the hollow hub of the back wheels, and an internal brake ‘shoe’ pushes outwardly against the drum to slow down the vehicle.Both types use friction to decelerate, between the disc or drum and a hard-wearing heat-resistant material such as composite steel and resin on the brake pad or shoe.
Brake pads are made to withstand extreme heat and wear from pushing against the disc, but no brake pads (yet!) last forever. Brake pads will need replacing when they get worn down to unsafe levels.
