My brakes have been squeaking for months. I took them to get fixed and the mechanic said there was nothing wrong with them so he cleaned them and now they squeak and grind when i stop more than ever. What could it be??

Hello sbruer07


Brake squealing is produced by high-frequency vibration in the brakes. With disc brakes, vibrations can occur between the pads and rotors; the pads and calipers; the calipers and mounts; and/or within the rotors themselves. Trying to fix a squeal problem the wrong way can often make the problem worse. If somebody does a quick brake job and replaces the brake pads but doe snot resurface the rotors, the result can be an even louder squeal. The same can happen if the rotors are resurfaced incorrectly, too quickly or with dull tools. Excessive rotor runout can also cause problems.
