If you want to see some good drum brake action, watch the Corvair captured in this guy's video. (hang in after the first pass, it doesn't stick :) )
Drums all around (rules restricted to what was available from the factory)
Just shows for those who want and those who need, they can be made to work pretty well, at least for a while. Kindof like anything in a long race, got make it last.
Pretty cool, although I'm sure he'd prefer decent front disks given a choice.
