How to put piston back in caliper.....

[fenderpicks]

Okay i spend like 12 hours on changing my rotors and paint my caliper....
While i got the passenger side put back on... my driver side's brake caliper started flooding brake fluid and next thing i know the piston fell off.... i stretch open the little rubber thing and stick the piston back in.... but is only half way in and half way out....
i used as much force to push it in but it just wouldnt go all the way...
How do i fix this...

Sorry dude, but my feeling is you are better off buying a new caliper. you pushed out the piston and the caliper needs to be replaced or rebuilt, the caliper is compromised, dont trust it.

Whenever I changed my mom's brake pads the other day I used a C-clamp to push the piston back into place. It didn't come all the way out like yours did so idk if that makes a difference, but I know that I couldn't have pushed it back in by hand. If that doesn't work i would def have a pro look at it, because you can't compromise your brakes.

true, but I have a feeling he had both calipers off. when he went to compress the passenger side the pressure of doing so pushed out the driverside piston, as far as im conscerned he most likely needs a new caliper because it will never seal fully. If im wrong please correct me OP. when compressing caliper pistons always have the other ones on or that can happen.

Well at last i got everything back in and fixed up.... geez noobie spend over 12 hours just trying to figure out how to change out some &*^&*%^&*$%^^^$# rotors... and paint my caliper that at the end got brake fluid all over and need to be repaint tomorrow -__-

Sigh... i did my hw in research but too much unexpected happen....
