No brakes usually means one or two things a leak (in a hose, line,wheel cylinder or caliper) or a bad master cylinder if its full of fluid and doesnt spray out under the car its probly not a leak a way to test the master cylinder is to pinch off all the rubber hoses at the same time and see if the brake pedal is rock hard if it still sinks to the floor youve got a bad master cylinder the hoses will be close to the wheels within a few feet at least make sure you dont pinch the hoses too tight because you can damage them only compress them in half just to where the vise grips are tight cheking the wheel cyliders will require removal of the wheel brake drum (which can be difficult spray wd 40 or similar on the center and through the luggnut holes and smack around the edge with a hammer to break loose you might have to pry a little) amd pulling back the rubber boots on the cylinder if fluid comes out its bad even a little is enough hope this helps post more if no help good luck
