Pontiac Repair: abs brake system, pontiac bonneville, rubber line

Question
I HAVE A PROBLEM W/ THE BRAKING SYSTEM ON A 95 PONTIAC BONNEVILLE 3.8 V6. FIRST THE MASTER CYLINDER WAS LEAKING IN THE REAR SEAL SO I REPLACED IT MAKING SURE TO BENCH BLEED IT FIRST. THEN I TRIED TO BLEED THE SYSTEM AT EACH WHEEL.I DID SO ON EACH ONE EXCEPT THE LEFT FRONT WHEEL.I TRIED TO BLEED IT AND ONLY GOT A LITTLE BRAKE FLUID OUT. I DROVE IT DOWN THE ROAD AND THE LEFT FRONT WHEEL WAS BREAKING HARDER AND HARDER. CAME BACK THINKING THE CALIPER WAS STICKING SO I REPLACED IT.DROVE IT AGAIN AND IT DONE THE SAME THING. CAME BACK HOME THINKING IT WAS THE RUBBER BRAKE LINE THAT IT MAY BE COLLAPSED. DROVE IT AGAIN AND STILL THE SAME THING.NOW IT WONT HARDLY MOVE. I HAVE BLED ALL 4 WHEELS MAKING SURE TO TOP OFF THE MASTER W/FLUID AFTER EACH TIME.I HAVE CHECKED THE CALIPER AND FOUND IT TO BE FINE.IT JUST WONT RELEASE THE FLUID PRESSURE.THE LEFT FRONT IS THE ONLY ONE STICKING! ANY SUGGESTIONS?  

Answer
Hi, I take it you replace the rubber line. take the line a loose from the wheel then trun the key switch on and see  will the fluid will continuous to run, then trun the off and see will it stop. and if it does stop running then it would be in the ABS, and this would have to go to a repair shop.
