Brake pads are one of those car parts most drivers don't think about until they start making noise. Unlike engine oil or tires, there's no universal mileage number that tells you exactly when brake pads need to be replaced. One set might last tens of thousands of miles, while another can wear out much sooner.
A typical set can last roughly 20,000 to 60,000 miles, although the actual lifespan varies significantly with driving style, vehicle weight, brake design and road conditions. So, how do you know when yours are running out?
