On average, brake pads begin to wear out around the 20,000- to 30,000-mile mark, but there are many factors that may impact this figure. Knowing what signs to look out for will therefore prove instrumental in detecting when your brake pads need to be replaced. If you feel your vehicle taking longer to come to a stop or notice a high-pitch screeching or grinding noise when braking, scheduling a checkup is integral. Running with worn brake pads will eventually affect the rotors, which can be a costly repair, so taking a proactive approach will not only keep you safe but save you money as well.
