Getting pistons out?

For really stubborn pistons we use a lever action grease gun - they put out 10,000psi.

If everything's clean enough....your hands.

I cant put it back in! why not

Just push them back in with your hands, straight. Do not cock them over slightly or you will royally fuck things up. Use a little brake fluid to lube it.

oh no, I did use brake fluid to lube things up, but it still wasnt going in, i used a vice to cram it back in and nothing was happing till it just sorta snapped back in.... is this bad? I now when i've hooked it all back up nothing is happening when i pull the brake lever.... I think its just a big air lock so ive taped up the handle to let all the air raise to the top......

It is only likely to be bad if you've either scratched the working surface of the piston (it'll leak pretty quickly), or you've snapped part of the inner caliper housing off (it'll leak pretty quickly). If it is not leaking, you're probably ok. You really shouldn't need a great deal of force to reassemble them, just the right force in the right place. I'm guessing that if it doesn't want to bleed up, you've let the master cylinder run dry, and it needs tp be primed. Use the search function, I've mentioned how to fix this a few times.

Yeah ive got it fixed now, it was a giant air lock. I tired for 2hrs to put it in nicely but i couldnt get it....... how do u put the pistons in nicely?? To get it out i had to hook it up and pump the brakes to make it come out.
