Please help: Caliper piston stuck, needs pushing back.

Yesterday I removed my brake caliper to see if i could find out why its making a squeeking noise.

i took the pads out and for some dumb reason pushed the brake pedal once.

now the piston is out too far to put the pads back in and fit it back on the disc. its about 10 mm out to far.

i've tried using wood, screwdriver etc to push it back in but it won't budge. I've even took the top off my brake fluid just in case but nothing seems to work and now my bmw is stuck on my drive.

Does anyone know of any tricks to get it pushed back in?

please help!!!

your gonna have to try two things, a nice big set of "C"clamps or your gonna have to dissconnect the hose from the caliper and use the C clamps, than you can re attach the caliper and bleed your whole system over.

he shouldnt have to take off the hose i dont think... if you get some muscle on the C clamp and have the top of the brake fluid reserve it should slowly but surely come back in...

no i realize that, but thats like last resort stuff, the reason the piston has the resistance it does is because of the pressure in the system, C clamps are the only thing i use normally

thanks guys.

i'm gonna get a c clamp tomorrow and give it a go.

i think the caliper has seized completly. i'd replace that myself, but the hose connections are rusted solid.

just hope i'm gonna be able to free it up, the last thing i need is to have to get a tow truck.

get two things, a nice looooong pipe to fit over your wrench for teh leverage, and get 2 cans of liquid wrench. That shit will break up any kind of corrosion you want.
