1998 Chevy Lumina 3.1 mileage: 96,000. When I press the brakes to slow down the car will slow in a lunging fashion. I replaced the front brakes and rotors about 2 years ago because the rotors were warped. It feels like the same thing all over again. I have 4 wheel disk brakes and when I apply them with medium or hard pressure the car stops great. I don't know if this has anything to do with it, but I have dust shields on all four wheels. Other than that, the car is stock. Any ideas on what might be causing this?

Assuming that you properly tightened the wheel lug nuts to the proper torque, the dust shields may be holding in the heat generated by the brakes causing the rotors to warp.
