[NoVa-Corvairs] Look Ma-No Head!

I sanded mine once to get by until I could get to the states and get good ones. Sanding works, but is not permanent if the material is lousy.

What? Replace? Back when I was in college (no money), I just took the shoes into the wood shop and used the stationary disc sander to deglaze my 50 Studebaker shoes. AH, and that was in the days of asbestos linings too!

I guess it was no worse than those mechanics arcing brake shoes to fit drums.:-(

Yes, replacing glazed shoes is the correct repair, even today with non-asbestos linings.
