2004 Yukon rear brake lines.

Thanks for the great info. I was wondering the same thing about complete brake failure. Isnt that not supposed to happen? Problem for me is my mom has my Yukon and I have to always do my best to keep up on maintenance. She was pulling out of the driveway and the pedal went completely to the floor. Luckily she was able to just back up into the driveway. When she called me I asked her 'is there a big oil stain in the driveway?' Of course there was and she didnt notice it. But that is scary to completely lose your brakes like that. I thought they fixed that problem in the early 70's.
