Most of the time when I brake at low speeds I hear a clicking type sound, that is fairly faint. I do NOT hear squeaking, grinding or any high pitched noises that might indicate my brake pads are wearing down, or anything that sounds really bad. I also do NOT feel anything in the pedal with the clicking/tapping. It seems to come from the front left tire, but I can't say for sure.
A couple months ago I did have to get my rotors resurfaced, and I believe they put new break pads on at the same time.
What could be the possible causes? How serious of an issue is it likely to be?
