Brake Disc Rotor problems of the 1996 Mercury Cougar

The rear brake rotors need to be cut due to warping. This is the first problem with the rear brakes but, the front rotors have had to be cut down every 12,000-15,000 miles since new. At 48,000 miles the front rotors could not be cut any more and needed replaced. They were cut three times before being replaced. I had a similar problem with a 1989 Mercury Cougar and Mercury did find a problem eith the rotors being to thin. After being replaced I never had another problem with them for over 70,000 miles. I'm trying to find out if there is any know problems or repairs for my car.

The brake rotors have rusted, resulting in car making noises and after the brakes were applied, the steering wheel vibrated. Please give more detail informaton.

The first time the front rotors had to be resurfaced the vehicle only had 10,000 miles on it, than it was resurfaced again and finally we had to have new rotors installed. The same problem started happening again causing the brakes to wear, rotors resurfaced again, than new tires in the front were wearing out of rounds, now this will be the fifth time we have to have the rotors repaired (resurfaced). The steering wheel vibrates terribly when applying the brakes due to this problem.
