2004 Toyota Camry brakes problems

Brakes failed to work when going over bumpy roads, aslo brakes do seem to wrok as\ design (to stop) when immediate action is required. I press the brakes when trying to stop and avoid an accident howver the brakes did not appear to work and the car jst kept on going as I the brakes did not exist. I press hard with more than adequate time, however the brakes did not even slow down the vehicle. Something should be done before someone gets seriously injured.

Tl*the contact owns a 2004 toyota camry. While driving 55 MPH, the contact stated that the brake pedal depressed approximately two and a half inches before the brakes made hard contact. There were no warning lights, noises, or leaking fluid present. The dealer adjusted the rear brakes, however, approximately 3-6 months later the failure recurred. The current and failure mileages were 47,000. Updated 01/02/08. The consumer stated the brake pedal travels before it starts slowing down.
