Replaced my rear brakes and flushed both ends. what came out reminded me of theme song from the Beverly Hillbillys. PO changed the front at some time but the rears were factory with 22k miles. Fluid was black but finally got good clear fluid coming thru. What a difference now, no more spongy feeling. All set to get Kawasaki brand pads but ended up with the EBC brand for half the price.
