hi all. I have a pair of Shimano 105 9 speed brake calipers with about 3000-4000 miles on them. Today I replaced the brake pads with ones designed for carbon wheels since I will be using those in some races. I had to do a very minor cable adjustment to account for less wear on the pads, but otherwise was about as straightforward as you can imagine.
The thing is, now the rear caliper doesn't "snap back" all the way, which often leaves one side rubbing the rear wheel a bit. The problem is not the new pads grabbing, they don't just stay stuck on the wheel. The caliper itself is not returning all the way to an open position. I cannot see anything obvious wrong with any of the parts of the caliper. The spring looks intact and in position. If I loosen the brake cable, then without that pressure against it, it snaps back no problem when I squeeze the calipers by hand.
So, I am trying to figure out what to try next. My first thought is to try putting the old pads back on, even though I can't see how that will make a difference. It's the only thing I changed, though.
If that doesn't work, I am thinking replacing the cable is the next thing to try. It's a pretty new cable, but possibly something it is part of the problem.
any other thoughts on what to try?
Thanks in advance for the help
