if your pads are thick it should not flop around...if your pads are ready for a replace,,,,it still should not flop around but rather ,be weak and squeeky even.....your caliper works by sliding two halfs towrards each other...one is fixed to the fork leg and the other moves on the slide bolts or carrier blots...which by the way need greasing when the brake is serviced.....the only thing i can think of is that your pads have enough to allow excessive sliding of the one half under brake onset.......does this help at all......by the way ,i know very little ,so wait for a second answer....:laugh:
