Angry Replaced front pads and rotors, now no pedal!

I just finished replacing the front rotors and pads on my fiances 2004 Focus Se. Now there is no pedal, goes almost all the way to the floor. It's better if we pump the brakes once or twice before trying to stop. I had to compress the piston back into the caliper to get the new pads in. I have been doing brakes for over 30 years and this is the first time this has happened. Any help will be greatly appreciated! She's threatening to divorce me before the wedding on May 17th. HELP!!!

Shucks, that's usually such a simple job too...

Any issues with the fluid that pumped back into the reservoir? Did you have to suck any out or add some again later? Hose from the master back up to the reservoir still look OK? Did you happen to do one at a time & pump it up between or was it all at once.

Pumping it up again when done is normal, as I'm sure you're familiar with. Staying "soft" is rather unusual.

Take a look at the calipers as someone presses the pedal to look for excessive movement - that's sometimes a problem if everything didn't go back together quite right or the new pieces aren't proper. (I actually had a set of pads cut at an angle not long ago on one job, bad enough to be obvious fortunately or it might have driven me nuts)

Luck

Question Replaced front pads and rotors, now no pedal

Yes, I did both sides then checked the pedal. There was south fluid forced back to the reservoir it made a puddle on the ground. I have removed the master cylinder and checked that, bled the entire system with new fluid and checked all the fuses for the ABS system. I'm still at a loss!

No, the pedal is fine, perfectly fine, when the engine is off. Only when the engine is running does the pedal go to the floor. It pumps up a little if you step on it a couple times when stopping but nothing like its supposed to be. I bled the system with a brand new vacuum bleeder and new fluid and bled it until the new clear fluid was coming out. What about the ABS system? All the brake lines go into a metal box with what looks like a motor in the front. Is that the booster and ABS system? Does that have to be bled separately? I'm still confused

that metal box is the solenoid system for the abs. its where all the pulsing happens when abs is activated. its also where all of the air bubbles love to get trapped when bleeding the brakes the old fashioned way. your only option is to take it to ford so they can finish bleeding properly. (they have a very advanced tool called a modis its like 3 grand to purchase one it can cycle the solenoids in the abs pump housing as well as extremely in depth diagnostic work. )

maybe. the solenoids just need to get the air up and out. if you feel confident enough to try this do it on a country road that isnt well traveled.

bleed the lines again, and make sure to top off the reservoir multiple times after every pump.

Use some surgical hose on the bleeder nipple so that you can see if any bubbles come out.


Also, i never trust those vacuum-based bleeder systems, they have failed me before. Get a friend in the car pumping while you release/tighten the bleeder.

You must have air still trapped some where. Being that you opened the system completely when you took the master cylinder off there will definitely be air in the system after that. Try getting a helper to pump the pedal while you bleed it. I have had to do this a few times even after using a brake bleeder pump.
