1992 Oldsmobile Cutlass Supreme warped brake rotors

1992 Oldsmobile Cutlass Supreme mileage: 135,000. This car has been warping rotors within 10,000 miles. I know to use the emergency brake at least once a week, and to keep my foot off the service brake when releasing it in order to allow the rear calipers to adjust properly, been doing this since I got it with 74,000 on it. I believe this to be a problem of design, too small of a pad, and rotor, my Daytona's are bigger. I saw where you mention heat shields, if I remove them will that reduce this problem?
