Tim,
I definitely have drums on the rear. Not sure when/if they quit using drums. Maybe for smaller (mine is 27') MH they used drum and disc for larger?
All,
I picked up new shoes earlier today and found out that my shoes are hardly even worn; maybe 1/32 or 1/16 at the most. Also noticed that the trailing shoe lining is definitely much thicker, so my wear pattern appears to be normal. I will return the shoes, springs, cylinders since I don't really need new shoes at this time - this was more of an inspection, fluid change. It was all worth it because I also found that one of my wheel studs had 2-3 threads completely stripped. Back to the auto store for new HW. I will replace them all and get new nuts as well.
