Brake Problem

:banghead: Ok my front pass. side rotor is gone my outside pad fell off, and the brake pedal went to the floor. I replaced the rotor and pads and compressed the piston all the way down but the brake still doesn't respond. Whats the deal??

um did the piston fell out of the caliper bore????

if so, did you check for the square-cut seal inside of the caliper housing to see if it's there???

any brake fluid leaks???

i can't check it over the internetz
