So while changing my front brake pads....my neice got in the car and hit the brakes ....now the piston is on the rotor, and i can push it back to remove the caliper but it won't go all the way back....i don;t know what to do

Use a "c" clamp...

 

Geeze if that pic is what I think then bleed the brakes till the Caliper comes off to put the pads back in..being compressed in the disk is hard but releave the pressure a little by bleeding then take it off rocking it back and forth. Then like Sharkey said use a C Clamp with a piece of wood between and slowly compress it back...make sure the nut is tight where you bled it though...then that should solve the problem...hope that helps...scary

 

that sucks! bleed the system and hope you can get something between them to push them back

 

I was able to push it back some but loosing the rotor.....I can get a flat head screwdriver in between the piston and rotor, but non of the pistons won't go back anymore all the pistons are all stuck at the same height

I do see the psition move up if i slightly tap on the brakes.and go back just alittle bit.

 

Use something called a caliper spreader can pick up at any local auto store but any previous method would work as well just this maybe more efficient.

 

I tried taking one of the wooden shims and using the flat head scree driver and it still wouldn't move back

 

Put lug nuts on the rotor to keep them from wobbling.

The pistons will need to be gently rocked in with 2 screwdrivers, one piston at a time.
While you do that the bleeder should be cracked open to relieve pressure.
Should be 2 people one to push piston in, and the other to close the bleeder when you stop pushing.
Any brute force will damage the piston seals, not the boots you see, but the seals that act as rings in the caliper walls.


What I personally would do, is to remove the caliper, completely pop out the pistons and install new seals. Then bleed the complete system.

 

Release the pressure from the brake lines by uncrewing the nuts behind the brake caliper

 

As has been stated, remover the caliper. No need to damage the rotor. Shouldn't be that hard to push in if you do what's being recommended and loosen the bleeders.

 

Winner winner.....
