Got rim brakes? Do yourself a favor and give them a quick overhaul.
I had a sluggish dual pivot front caliper so I watched a couple tear down videos and went at it. The difference in feel is truly astounding. The rear seemed fine, but now that I was an expert I figured what the heck. Again, the difference in response and feel was amazing. After the overhaul my brakes are so much lighter and more responsive, I just wish I had done this many many miles ago. The tools, time and skill required are minimal and the reward is great. There's so much crud going up into those bushings I bet it doesn't take more than a few thousand miles to affect performance, maybe less depending on conditions.

I was just working on an old side-pull brake at the non-profit, and on old pro there said to be sure to lube where the spring rubs against the caliper. It all makes a difference.

Which dual pivot calipers did you rebuild? Just curious.
I like the original Dura Ace dual pivots - the 7403. Very heavy by modern standards but these are super re-buildable. They use a nylon pivot bushing with tiny ball bearings that can be carefully cleaned and re-greased. When reassembled with fresh pads and high quality cables and housings and clean, machined rim sidewalls... wow! I agree with you, the difference can be quite startling.
