I replaced the drivers side front caliper, and bled all 4 brakes starting at passenger rear, drivers rear, passenger front then drivers front. After bleeding the brakes, the pedal still goes to the floor. It seems like during the pumping of the pedal during the bleeding process the caliper I replaced is loose as in it wiggles with the cylinders moving. Is this a bad caliper or? Any help would be helpful.

Was the fluid kept to a good level during bleeding? It may not have causing your problem you have now the caliper may be loose due to being a floating caliper but rebleed it and see what you get with the other you may have a bad master and or air still in the ssytem

Yes the fluid level was keep at a good level. The cylinders inside the caliper never moved when the brakes were bled, the one I replaced. I bled the breaks several times and still the same thing.

If the piston in the caliper never moved it's frozen and needs replacement. Calipers should ALWAYS be replaced in pairs never one or the other. I still think you have air in the system someplace. This may need to be put on a scanner and abs unit valve opened to be bled to get rid of the problem.

MAYBE YOUR SELF ADJUSTERS ARE DIRTY/ WORN OR INCORRECTLY INSTALLED

BANKING ON THE DIRTY/ WORN PORTION

SEE "MY ANSWER" IN THIS POST (I PIPED IN ON JUNE 2, 2013)

https://www.2carpros.com/questions/1966-ford-custom-front-brake-shoe-noise

SOME OF IT MAY BE A REVIEW (MY WAY OF BLEEDING) THE ADJUSTING PORTION MAY HELP, HOWEVER IF THINGS ARE WORN WITH THE ADJUSTERS, YOU MAY HAVE TO INSTALL NEW PARTS

MAYBE THE WAY YOU BLED IT WAS NOT ZACKLY RIGHT?

REGARDLESS, LET US KNOW WHAT YOU FIND

Already fixed. Installed brand new adjusters all the way around so that's wasn't the issue. Had a bad brand new caliper, go figure!

SORRY YOU HAD TO GO THRU THAT

YEAH, SOMETIMES THE NEW PART IS BAD

THE BAD THING IS

YOU EXCLUDE IT FROM BEING A FACTOR

AND TEAR INTO THE REST OF THE VEHICLE

THE ONE THAT MESSED ME UP THE MOST WAS A "NEW" BAD IGNITION MODULE FOR MY 1979 JEEP CJ 5 ABOUT 25 YEARS AGO (I ONLY OWN REAL JEEPS FOR PRIMARY TRANSPORTATION-NEVER A CAR ) - I HAD RIPPED HALF OF THE WIRING OUT OVER A 3 DAY PERIOD. A FRIEND SUGGESTED THAT I HAVE THE "NEW" IGNITION MODULE TESTED

I WAS VERY SKEPTICAL AND HARD HEADED, THE DARN THING WAS "NEW" AND SURELY COULD NOT BE THE PROBLEM?

IT WAS!
