Bought car from dealer out of state. When it was off loaded and backed into my driveway I noticed the brakes groaned. When I drove it I'd get a little groan leaving the house when I applied the brakes, but never noticed it otherwise. So I just now installed new rotors and pads at a shop and it is still doing the same thing. The old rotors and pads were fine, no problem I wanted drilled and slotted. All four brakes make the groan simultaneously, the instant it comes to a complete stop if you keep you foot on the brake. You can finesse it if you ease up. I've searched the forums and their does not seem to be a definitive answer, answers ranged from more grease to your sister is sleeping with the mailman. The car has after market wheels and it has been lowered but I don't know how the lowering was done. Car rides and handles like a cadillac.
