[77newell]

My 77 still has them and they seem to work fine. I suspect the reason s-cam became the standard is the ease of adjustment when putting on lots of miles. I investigated the change and decided it wouldn't improve the braking performance and I wasn't having to adjust my brakes at all in the 10 years I've owned it so no gain there either.

If I were to make a change it would be to disc brakes since I believe they would increase stopping power and resist heat fade better. By using the Jake brake I have had no instances of brake fade so that issue is marginal for me.
