Squeaks, squeals and metal-to-metal grinding noises are typical signs you’re past due for new brake pads and/or rotors. Other signs include longer stopping distances and more pedal travel before you feel significant braking force. If it’s been more than two years since your brake parts were replaced, it’s a good idea to have the brakes checked at every oil change or every six months. Brakes wear gradually, so it can be hard to tell by feel or sound when it’s time for new pads or rotors.
