Another post got me thinking on this subject. Why is it that I can drive a vehicle for 4 or 5 years before the brakes need replacing but the wife drives a car for about a year and less than 5k miles and the front rotors are warped? When I took over the 93 from her I had to replace the front pads and rotors, And now the 02 that she drives needs the same! Never uses the parking brake either. Female Drivers!

Brake rotors are machined from gray cast iron and do not 'warp" There have been several recent threads on this, with links to brake sites, discussing the perceived problem. Look through Cadillac Tech Tips and Item Specific: Suspension, Brakes, Tires. Or Google "cadillac forums brake rotor warp information" or something close.
A possible "fix" is to get the car out on a lightly traveled highway - do several aggressive stops from 60+, driving away after each stop and do not hold the brakes on at the stop - what you're doing is scrubbing pad resin deposits off the rotors - these cause a nasty shudder that is usually described as "warping". After the last aggressive stop, drive normally for 5 - 6 miles to cool the rotors. The deposits come from sitting at long stops with the brakes held on.
