Just like gas mileage, the lifespan of brakes depends on how and where you drive your car. The brakes pads work such that it is pressed on the drum for the vehicle to stop. Although there is no clear schedule on when to replace the brakes, there are clear signs that the brakes are worn out. You will hear persistent squeals, squeaks, and grinding sound when stopping the car. The other signs include pulsations through the brakes pedal or the car moving long distance when braking before stopping. When you notice one of these signs, see your automotive technician immediately to check the rotors and brake pads.
