It depends on how frequently you drive and the driving condition. Most brake pads need replacement every 25,000 miles and above. The maximum you can drive without replacing the older brake pads is 70,000 miles. Even if you notice no signs of wear, consider getting the brake system inspected by a mechanic. Usually, the driver will notice the unusual signs indicating the need for brake pad replacement. If you observe the vibration and squealing sound on pushing the pedal, then that’s a sign you need to replace the brake pad. The durability of a new set of brake pads depends on the material and your driving habits. For instance, if you use the car for sports and heavy-duty driving, then you will need to replace the brake pads soon.
