When I got my 06 Yukon I got the extended warranty when the girl said it covered brakes. 65000 kms back brakes go. Pads and rotors, check my warranty I have $100.00 deductable and rotors not covered. Must use GM parts, GM rotors $235.00 each total so for $570.00 without taxes and labour. Needlessly to say fixed it myself with aftermarket parts for $155.00 and 90 minutes of my time. Oh yeh the dealer is a buddy of mine.
