After changing pads and rotors, a professional mechanic will always spray brake cleaner on the rotor and calipers. One of the most common causes of squeaking brake pads – consistent use means all brake pads eventually wear down and become thinner.

As a safety precaution, many manufacturers fit a small steel strip to the brake pad. This scrapes on the disc as the pad wears away and reaches its limit – serving as an indication that the pads need changing.

Squeaky brakes can panic a driver, as brakes are arguably the most important safety feature in automobiles. Sometimes the concern is warrante as the brakes are going bad. Other times, however, there ­may be nothing wrong at all. Some brake noise is considered normal.
