NHTSA Complaint #11229424 — 2011 FORD F-250

I CAN NOT GET THIS SOFT BREAK TO GO AWAY! IT NEVER HAD A SOLID BREAK BUT I BOUGHT IT USED AND FIGURED IT NEEDED A BREAK JOB. I HAD CALIPERS TO START LOCKING UP ONE AFTER THE OTHER WITHIN A COUPLE DAYS OF EACH OTHER, SO I REPLACE THEM ALL. THEN THE NEW ONES STARTED GETTING HOT. SO I REPLACE ALL THE BREAK LINES AND MASTER CYLINDER. AFTER ALL THAT I STILL HAVE A VERY SOFT BREAK, ALMOST AS IF THERE IS AIR IN THE LINES. I KNOW AIR CAN'T BE THE ISSUE BECAUSE THE BREAK SYSTEM WAS BLEED USING A MACHINE. NOW AFTER DOING RESEARCH ONLINE I HAVE COME ACROSS A LOT OF PEOPLE TALKING ABOUT THIS EXACT ISSUE. THIS NEEDS TO GET FIXED, THERE IS NO WAY TO TELL WHEN YOU ARE ACTUALLY HAVING BREAK ISSUE COME UP BECAUSE THEY FEEL SPONGY WHEN THEY ARE WORKING AT THERE BEST.
