You can have all the slack you want, but I still don't understand what you did to shorten the throw. Are you saying you pulled the calipers and then squeezed the lever with the pads still installed? What then? Did you push the pads back out or what? I'm generally happy with my SLX 4-pots, but curious.Meh, I was in the middle of my first ride on this bike, still groggy from flu pills. Cut me some slack. I'm 47 now.
