??? Not sure if it's different in a 75, but I have a hard time figuring 
how cornering can cause a component at the rear wheel to rub (since the 
relative positions of the wheel, hub, brake drum, backing plate, and axle 
tube are fixed). Regardless of whether the parking brake is installed 
correctly, the clearances shouldn't change under cornering (except for 
wheel flex & bearing end float, which would be a few thousandths at 
most). I would be a little concerned about the condition of the wheel 
bearing on that corner, assuming the lug nuts are tight. I may be 
overlooking some other possibilities, but on principle "it just don't 
seem right".

Joe Short had this to say:
