What is the typical pad/rotor life for the VX? I replaced the pads with ceramic ones (raybestos) around 50,000 miles. Now at 64,000, the brakes just dont bite at all like the used to. I had to apply a lot of pressure to the pedal, sometimes all the way to the floor. With the pads being new, is it simply that I need new rotors? The fluid and level are ok???

Thanks!
