Three problems related to brake disc rotor have been reported for the 1996 Chevrolet Lumina. The most recently reported issues are listed below.
Braking system malfunctioned due to rotors being corroded which cause extended stopping distance. Rotors resurfaced, but problem still reocurred.
State safety inspection mechanic noted that both front brake rotors were deeply rusted and/or pitted and should be inspected by a gm service center. The service representative at dagley Chevrolet Geo informed that both front brake rotors were rusted and pitted so deep that they could not be re-surfaced, they need to be replaced and the replacement would not be covered by gm. I looked at the rotors myself and find that the inside brake rotor friction surfaces are rusted or pitted away, aprox. 1/3 or less of the front inside brake pads are actualy making contact with the rotor surface. In my opinion, this results in a very significant loss of braking efficency.
Dealer told consumer to throw away front wheel rotors because the were too thin to grind. Nlm.
