^^^^ My take, is that any car that comes with rear disc brakes, would either have a mechanical device built onto the caliper, and when the brake handle is pulled or a brake pedal is pushed, the cam action (at he caliper) would force the pads tight to the rotors, and allow them to pull away when the handle or pedal is returned to its off position. Others (like the G8), use the spreading shoe design. I doubt any of them have the components added in, that would *auto adjust* those shoes (as time and use go by). I'm sure I will never even need to adjust those shoes (using its mechanical adjuster method) on this car, unless I choose to make them work as regular brakes from time to time (an wear the shoe thickness down). I also feel that these parking brakes have next to zero ability to assist in regular braking.
Its almost like "MEAN GTO" is lacking the shoe material thickness needed, or the wrong total diameter of the shoes currently installed in there, for proper parking brake action. Especially if a manual adjustment only lasts for like 1 or 2 cycles.
