Hi, I've recently noticed that if I have my driver's side window down and I'm coming to a stop (i.e., going less than 10mph) and I apply the brakes gently, I hear one dull clicking sound from the front when I press on the brake. If I let go of the brake and gently apply it again, it'll click again. The brakes are about 2 years old, but still have a lot of pad left. Anyone know what that could be?
