The same thing is happening to me, I just got new front brake pads and now they squeal almost all the time when coming to a stop. They only squeal at low speeds, when I apply the brakes gently. They do not squeal if I apply the brakes hard. Then, while I'm coming to a stop with the brakes squealing, the brake pedal pulsates and goes closer to the floor. It seems like the abs kicking in, but I'm not sure.
Have you guys figured out how to cure this? Has the squealing gone away...cause damn it is loud and annoying as hell. I'm going to take it to my mechanic sometime in the next week or two. I'll let you know what he says.
