Well i started noticing this a few weeks ago. When i bought the car a few months ago the brake pads were fine, as far as i know their is still plenty of pad left. But it seems whenever i press on the brakes pretty hard sometimes they will make a sorta groaning noise like they are straining. Also they ALWAYS squeak and they let of a ton of brake dust. So im thinking or replacing the pads with some nice ceramic ones. Anyone know of a really nice set of ceramnic brake pads? Also what could be my problem? Are my brakes just getting hot?
