Sounds like something's broke inside and occasionally getting caught. May be parking brake lining broke. Wife made me come and switch vehicles with her. I only heard it once. Drove forward and backwards with and without brake and parking brake applied. Beat it like I stole it home for about 3 miles and never heard it again. Can someone refresh my memory on how the self adjusting parking brake works on these? (05 Yukon)
