Guys, my son has a 2002 Tahoe 4wd that he bought used a while back. I am getting parts together to redue his brakes & I find there are two different rotor sizes for the six lug wheels. He didn't recieve much paper work with the vehicle so I need to decypher the numbers on the inside of the glove box door so we know exactly what we have. Does anyone have an explanation sheet to tell what all the code numbers mean. Thanks for any help.atriot:
