SOURCE: brake pedal goes to floor after bleeding the brakes many times
start off by pumping the peddle 25 times with engine off ... bleed the abs system (usually has bleeder valves near/on control unit). then bleed the rest as usual with engine off ... DO NOT turn the key on while bleeding abs brakes.
SOURCE: Need A Scan Tool To Tell ABS Computer To Bleed Brakes
WELL THERE IS A DIFFERANCE BETWEEN A SCAN TOOL AND A TOOL THAT IS CAPABLE OF OUTPUT CONTROLS SUCH AS THIS ONE A SCAN TOOL CAN BE BOUGHT FOR LITTLE MONEY ONE CAPABLE OF DOING WHAT YOU NEED TO DO IS MUCH MORE EXPENSIVE SNAP ON BRICK IS AN OLDER ONE WHICH WOULD WORK BUT EVEN THAT IS ABOUT $600 SO IT SUCKS BUT THE DEALER IS GONNA BE YOUR BEST BET HOPE THIS HELPS
SOURCE: changed front pads now pedal is spongy,but stops fine
Check for wheel cylinder leaks at rear wheels. Next master cylinder.
SOURCE: 1974 vw Beetle with no brake pedal....
adjust the push rod that enters the cylinder.Sounds like your not letting the fluid into the cylinder.Shorten the pushrod then try.If still no success extend the rod if that fails you have a faulty cylinder.Hope that was helpfull good luck.
SOURCE: I have replace wheel cylinder on 97 Stratus, bleed
Itsw very unlikely their is a problem with the master cylinder. When you pump the brake's to bleed them it uses up the vacuum and the brakes will be spungy because the servo isnt working properly. After bleeding leave it running for a few minutes then try the pedal it should be ok. If their is a problem with the master cylinder then the pedal would go all the way to the bottom but not spungy. You may need to bleed the brake on the other side to get all the air out of the system.
