2004 Mazda, model Mazda3 passenger car, front wheel drive, 16,000 miles. The rear wheels continually show lots of brake dust while the front wheels are always clean. This indicates most braking is done by rear wheels contrary to expectations. Dealer ignores my complaints.

Excessive brake wear and noise days after purchasing my Mazda3 I placed a call to the dealership where I purchased it. I stated that the vehicle's braking system was creating an excessive amount of noise and brake dust from wear. I was told that during the first weeks of a new car that this was expected. The gentleman referred to it as seating. However, after several thousand miles, mostly highway (no brakes required), the pads and rotors are both deeply grooved and worn. Most wear occurs on the rear brakes. Most all braking is done by the front; therefore, if wear should occur it would be present in the front braking system. Dealer requested permission to turn the rotors, which I declined. Turning the rotors would do nothing more than quite the vehicle for a few hundred miles, until the grooves and dust would reappear. This problem has been overtly obvious; however, nothing has been done. Vehicle's safety is compromised.

1)4 days after buying the car my front brake rotors had 3 large (1M wide more than.5mm deep) grooves and the rear brake rotors were starting to develop the same problem. The pads must have some type of hard metalic pieces in them that gradually destroys the brake rotors. 2)it's only a matter of time before the pads wear the rotors to an unsave limit. So, I returned to my Mazda dealer for service. Jim ellis Mazda of marietta 3)the service staff there was horrible and in the end did nothing to fix the cause of the grooves. The shaved an unspecified amount of material off my front rotors and insisted that it was within "spec". the vehicle was only 3 weeks old but now my front rotors are almost out of useable rotor width. They did not replace the break pads despite their obvious link to the problem. My back pads and rotors were not changed at all! when my brake system goes out due to their faulty parts there will be human costs and that's why I'm filing this complaint.
