Brakes are nothing to fool around with. Your car or truck is equipped with at least one, if not many, systems to let you know when your brake pads are reaching their worn point. Every vehicle’s brakes will emit a squeal and a whine when your pads get low. Brake pads are designed to get noisy when they are nearing their worn point, so even your basic, bare bones model will give you this hint. Newer, advanced vehicles are equipped with sensors that measure how much brake pad is left and will actually alert you via a dashboard warning light if your brakes need to be replaced soon.
