I had the wedge brakes replaced on my '73. I took it in to a shop to replace some broken wheel studs and they left one of the broken studs in when they bolted it back together. The brakes failed on a trip and I had to get them fixed on the road. The shop had problems getting all the parts they needed for the older wedge style so they replaced them with s-cams. I didn't notice any appreciable difference after, but the shop did tell me that they would be much easier to adjust.
