Brake Disc Pads problems of the 2002 Mazda Tribute

I own a 2002 Mazda Tribute with only 47,475 miles on it. In the past 6 weeks I have noticed when stepping on the brakes on dry pavement the antilock brakes kick in and the pedal goes to the floor unless I pump them. This has become very dangerous as it is happening more frequently. I had my son look at the brakes to make sure it wasn't the pads and he found a broken tooth on the driver's side front abs ring which is causing the problem. I did some research on the web to find if there are any recalls and found no recalls for this trouble but I did find others who are experiencing the same problem. I will have to have the car serviced at an approximate cost of $800. 00. I feel that this must be a problem that needs to be looked into. A car with 47,475 miles should not have these problems. Please let me know if anything can be done to have Mazda cover this cost or if I have any other recourse.

Front disc brakes - allegedly worn out at 22,000 miles and now at 34,000 miles. 2 different dealers have looked at problem and declined to make a warranty claim. Now being told by 2nd dealer that rotors are "throw away" and need to be replaced along with disc pads. I've never had to replace brakes on any car with less that 60,000 miles.

When the brake pedal was applied, it went to the floor. The consumer pressed down on the brake pedal hard in order to stop and a squeaking nose was heard coming from the rear. The consumer was able to drive the vehicle to the dealer for inspection and the mechanic determined that both front rotors needed to be replaced due to corrosion. On 02/04/03 the brakes, rotors and pads had to be replaced 11 months after purchase, 03/10/04 the rotors and pads had to be repaired a year later, 05/27/04 brake squealing 2 months after repair the front rotors were replaced and pads sanded, 06/13/04.
