I have a 2001 Yukon XL 1500 series with an automatic transmission and limited slip rear end.
At about 3,000 miles the parking brake would not hold and was adjusted.
At about 12,000 miles the same problem occurred and was adjusted again ...
When it failed to work at 15,000 miles I just gave up on it and have not been engaging the parking brake.
At 36,000 miles I am now changing front and rear brake pads and realize that the parking shoes had warn to the metal drum.
I understand that a TSB was issued and a fix instituted for the same problem on the same vehicle when it has a a manual transmission.
I have not been able to locate any data on my specific vehicle.
Is there a fix for my problem?
I'd like to install any needed mods before installing the New Rotors, Brake Pads and Parking Brake Shoes
This is a long one, but all I could find:
