Hello,
I have had this same thing happen on my '82 C70. What I did to solve the problem was to remove the wheel and take the brake assembly apart. I cleaned everything inside really well with laquer thinner. Then I removed the 10mm nut and bolt that hold the actuating lever to the shaft sticking out of the backing plate and removed the lever. I then removed that shaft out of the brake backing plate. That shaft was corroded onto the backing plate on mine which was the main cause of my problem. Clean that shaft really well and then grease it a little where it goes into the hole in the backing plate. I also put a small dab of grease on the flat end of the shaft where the shoes contact it. Now reassemble it all. That cured all of my brake sticking woes and the bike has stopped great for several thousand miles. I also did the same procedure to my front brake at the same time. Another possible but less likely situation could be that the brake lining is starting to separate from the shoe itself. I had this happen to me shortly after I bought my '82. The linings came unbonded and locked my rear wheel up tight.

If it makes you feel any better, I've got 7K & the previous owner NEVER changed the pads, or at least the front pads...Bike still brakes but obviously my stopping distance is increased.
