I am irritated with the Dia Compe 981 brakes. I replaced the front pads right before the ride, and the cams setting the pad alignment shifted several times during the week. I corrected the alignment a few times before the ride, but I didn't bother messing with them once the ride started (I rarely use the brakes on a long road ride anyways). The brakes still function, but they produce the annoying squeal typical of misaligned canti pads.
I'm not sure whether I'm following an incorrect alignment procedure or if the knurling holding the cams in place is just worn out. At this point I definitely prefer threaded pads to smooth post pads.
Now that I'm back to commuting, the squeal is annoying enough to motivate me to look at it again.
