I'm working on my 2014 fusion Titanium AWD
I accidently overextended the brake caliper piston while replacing the brake pads. And now I can't get it retracted, even with a C clamp. I had already replaced the pads on the DR side and everything went just as planed. The cylinder turned easily with just a socket on the driver end. I could turn it with just the socket and NO socket wrench.
On the Pass side, I unhooked the electric connection to the motor that extends the pads and removed the motor, just like on the other side. The Pass side was not as clean as the DR side was, at first glance. I put a socket on the driving end and it was tight, and had to use the socket wrench. It was un-expectedly tight to turn, so being a dumb ars, I turned it the other way. It went easier, but was the wrong way and over-extended it.
Is it trashed?? Now the screw will spin and spin... and even with a C clamp I can't compress the piston. It stuck with about an inch to go to be fully retracted.
Thanks all, in advance. Any help would be greatly appreciated.

Calipers are pretty simple. Over extending them does not ruin them, but trying to force them back in with clamps and stuff can damage them for sure. If it came apart and you tried forcing it in many things could have happened, damaged piston, damaged bore, or damaged seal. All of which are critical to the brakes properly functioning.

If the piston over extended and was sloppy loose I would say, either take it all the way apart and inspect it for damage if you forced it, or install a new/reman unit.

Edited: I didnt read the whole post. . .

Hi Dlee and welcome to the Ford Fusion Club. We are moving this thread about repairing your brake caliper to the Ford Fusion "Suspension and Brakes" sub-forum, where it will hopefully receive more appropriate viewing and help from other Ford Fusion Club members.

On a related note: There is a "Service Mode" which must be enabled before working on the brake system. It is explained in the Onwers Manual. Did you enable the Service Mode before you worked on the brakes?

Good luck.

Thanks for your help. I'm new to this site and having a problem finding the correct area to place this posting.

Hi Dlee. All is well and no worries.

I also added information to my previous reply about needing to enable "Service Mode" before doing brake work. Not sure if you saw it?

Good luck.

Thanks for everyone's help. After finding out that I didn't wreck them, I looked at them closer and was able to screw the cylinder back in after renting a brake replacement kit from a local auto parts store.
FYI... I did not put the car in "Service Mode". I read that it would not be necessary if you remove the electric motor from the caliper before adjusting the piston.
New pads are on, No warning lights, brakes seem to be working fine.
Once again... thanks all
