Brake Disc Pads problems of the 2009 Mercury Milan

On 4 occasions, while in motion (3 times while coming down a hill and hitting a speed bump in apartment complex and 1 time on the interstate after hitting a small pot hole in a construction site) I hit the brakes and after hitting the "bumps" my brakes "went out" for about 20 feet where the brake pedal floored and didn't decrease the speed of the vehicle at all. When the brakes start working again, my car begins to skid forward until I let go of my brake pedal. The pedal feels like the abs kicks in. In addition, over the past 6 months, roughly, my brakes have become very "soft", requiring alot more pressure to stop my vehicle. I just had my brake pads and rotors replaced and that did not correct the problem at all. Nothing else was said to be wrong with my brakes during the service appointment.

When I pressed on the brake to stop there was a cracking sound then the brake pedal went to the floor. When I drove forward and pumped the brakes they were almost normal. Had a mechanic check it out and brakes were normal to him. Did it three more times. We had pads routers and one galiper on the back tires replaced. Also bled all 4 brakes. Was ok for a few days but started again. This happened on the highway and on country roads. Also had the tires rebalanced and aligned but nothing changed. I'm afraid to drive it.

The contact owns a 2009 Mercury Milan. While driving approximately 40 mph she applied the brakes and the pedal began to pulsate. The failure began to recur whenever she applied the brakes. She examined the vehicle and noticed that the brake pads were excessively and unevenly worn. The vehicle was not taken to be examined for the cause of failure and was not repaired. The failure mileage was 21,000 and the current mileage was 24,000. The VIN was unavailable.
