Adjusting, (or at least checking) the cams is VERY recommened. I did new shoes, front drum, flex lines and rebuilt front cylinders last fall. I finally took it to my mechanic because I just couldn't get it bled worth a damn. But now, it brakes about as well as my 4Runner.
Makes me wonder how bad my 4Runner brakes have gotten.
Looking back, if I had more money last year, I would have liked to go for new cylinders, as I imagine my home done hone job couldn't have been top quality. But no sign of leaks yet.
