Each component of a vehicle performs an important function that ensures the car runs safely and soundly. A working brake system is vital to vehicle safety, so any issues affecting the brakes merit attention. Fortunately, there are various warning signs that indicate to vehicle owners it is time to replace brakes.
•Grinding sound: Sun Auto Service says a deep grinding metal sound indicates that brakes are wearing down. Brake pads typically come equipped with tiny metal ridges on the bottom of the pads to alert the driver that the pads have worn down. Continuing to drive like this will put metal on metal, which can damage the rotors.
•Squealing sound: Some brake pads have built-in wear indicators. A driver may notice a squealing, screeching or whining noise when the brakes are engaged, says Bridgestone.
