<VV> Power Brakes for Corvair

[John Kepler]

I have heard that metallic shoes grind the drums away.

Not really, though I prefer Kevlar/organic material!  

Look, has anyone reading this EVER just straight up and down worn out a
drum?  How about a rotor?  No....things like "our friend-corrosion" and the
"stupid pet trick" of running the pad/shoe material beyond its use-limit
into the backing plate is FAR more likely to prematurely ruin the drum/rotor
than any "grinding" caused by any semi-metallic brake compound!  What works
best, IS best!
