One problem related to brake disc rotor has been reported for the 2000 Chevrolet Suburban. The most recently reported issues are listed below.
I took my 2000 Suburban to the garage before leaving on vacation in June of 2004 both back rotors needed replaced. Both were so rusted they couldn't be machined. They had to be replaced. Then in July of 2005 before going on vacation both front rotors were rusted. They must be replaced also. Because of the rotors being so rusted it caused the back brakes to become worn out and now they need to be replaced also. You spend over $35,000 dollars on a vehicle so you can be safe and have a safe vacation and before you leave it costs you hundreds of dollars. You would think that for the price you spend on these vehicles, that the company could at least use metal that would not rust and fall apart within 50,000 miles.
