I've read about guys filing down the pin in the master cylinder for better brake feel. My sazook brakes suck, despite galfer pads and waves, braided lines, and motul RBF600....
I would try Vesrah RJL series, although I've heard good things about PF. The only possible down side to PF is availability, for a while I was unable to find any to try. That situation has since been cleared up but it does make me leary about future purchases. The only other possible issue is the PF compounds. It was strongly suggested to get the rotors bead blasted if I was to try them, unfortunately I ran out of time. The EBC and Vesrah were very compatible. I can't comment on Galfer/Vesrah.
