I HAVE THE SAME PROBLEM WITH EVERY THING CHANGED IN MY BRAKE SYSTEM AND THE PEDAL IS VERRY SOFT IT PUMPS UP HARD WILE THE TRUCK IS NOT RUNNING. WHEN I START THE TRUCK IT GOES TO THE FLOOR. I HAVE A 95 GMC SERRIA. I HAVE CHANGED ALL THE COMPONENTS AND STILL SAME PROBLEM. I READ ON SOME ONE ELSES THAT IT MIGHT BE THE PROPORTIONG VALVE NEEDS TO BE BLEAD BUT I DONT SEE A BLEEDER

By everything I'm assuming you replaced the calipers. Go out and look at the calipers and tell me if the bleeder screw is above or below the line fitting.

OK, just making sure you had the calipers on the correct side of the truck. I'm afraid what you need is a professional scan tool. The ABS system has to be bled internally and that is done electronically using the scan tool.

Nothing is going to get you a brake pedal besides bleeding. I have been there many times and spent entire days and gallons of fluid trying to do it without the scanner and it's pretty much futile.

I don't mean go to Autozone for a free code reading. You need a professional, interactive scan tool that has brake bleeding software in it. There is a brake bleed sequence it will go through while your holding pressure down on the brake pedal.
