Brake pads are used to create friction when a car slows down from a high speed, so they are a very important component in a vehicle. Brake pads will need to be replaced every once in a while to keep them working as well as they should Usually, the guidelines say that brake pads should be changed after every 50,000 miles the car does. This isn’t accurate for every single car though and you should check your manual or check with a garage if you want to know the figures for your specific vehicle.
People who brake more sharply may need their brake pads replacing more often, so it’s important to brake slowly and gradually whenever you can. Brake pads can be melted onto the brake rotor if a car drives too fast and creates too much heat. This is not usually the case for non-racing cars though. Listen out for a slight squeaking, which could indicate you need new brake pads.
