One would think so, but not the case, given the hardness of the brake shoe lining material, they’ll ride along for many miles on only a portion of the shoe surface. There were machines in the shop to grind the shoe to match the radius of the newly machined drum. And depends on the lining material, back in the day it was asbestos, quite resistant to degradation from friction and heat. I remember when the mechanics would blow off the dust after removing the drum with an air nozzle before starting a brake job, clouds of dust , walked through clouds of that many times, but that’s another story.....
