Matthew,

The newer shoes might even fit the replacement drums better than the old drums. It seems to be a vanishing concern to radius shoes to fit drums. I'm not certain if this is caused by the problems with asbestos dust or if drums have gotten so cheap that they are routinely changed along with shoes. If you inspect replacement shoes, once they have been scuffed in, which have not been radiused, you will find that as little as a third of the friction face is making contact. At that rate, the shoe will be worn out before it fully seats.

A few years ago, I went in search of a shop in my burg to radius some shoes for me. I realized that I was in deep doo-doo whenever City Brake said that they no longer had the equipment to do the job. City Brake does only brake work and they have been around since automobile brakes were nothing more than a leather belt wrapped around a flat pulley. I took it on myself to radius the shoes by fabricating a radius fixture to use on a 12" stationary disc sander. I dragged the sander outside to do the work and I still wore a dust mask with filters rated for asbestos. Although my fixture had no micrometer dials, I bumped it gradually to a tight fitting radius. The shoes came out pretty damn good, but, after all of that, it didn't seem to make a difference in the seat-of-the-pants.

George
