I use the CDC in spray form with good success. No one has mentioned the dog ears on the ends of the pad. Be sure the channel they travel in is clean and smooth.

Also, I tend to not wash my cars as much during an extended dry spells - they stay clean so I don't need to. The down side is brake dust can accumulate and cause squeaking. Part of your issue may be dust build-up. Shoot those rotors well when you wash.
