One problem related to brake disc rotor has been reported for the 1999 Chevrolet Cavalier. The most recently reported issues are listed below.
Had to have rotors turned at 14,000 miles; then found they were rusted and needed to be replaced at 33,200 miles. Found there was no backing plate to keep rotors from rusting; dealer admits nothing about design flaw and says the repair is not under warranty. Had rotors and brake pads replaced at a surprisingly honest midas, where they said it's likely I will need to do this all again in two years because of the poor design of the disc brake system.
