Brake was slightly stuck, so used the airline method which moved it ever so slightly then went back to bleeding. Got it this far then lever went slack again, any tips for getting it out now so that I can clean it up?  |

Where abouts are you
Anybody near with internal bearing pullers
Either that or get a pair of plumbers grips, wrap the piston with something to protect it and twist it out.
Can't be much still in

I made an adapter and use a grease gun only on stubburn pistons. Down side being cleaning all the grease out.
sounds like it's a bit skew wiff on the very end of travel spray it with some lubricant press it back in a bit and pump it back out again.

Depends if you want to re-use the piston, if not then a good set of grips clamped around it and twist it out, if you are going to clean it up then you'll have to either connect it back up to the master cylinder and bleed it a bit then pump it out, but it does look like its nearly out, if that won't work then I resort to a grease gun, messy but effective.

Would think you're out of fluid if you've pumped it out that far? But as mentioned, a grease gun is the best method, nothing has defeated me yet  and less likely to loose any fingers. I've found any type of lube spray will make the seals swell and doesn't help much, read on here a bit of heat to melt the seals is another way. Doubt thats the most pleasant way either, at least not in the oven |

Ran out of fluid, more fluid in, piston out. A quick wipe revealed this blue paint underneath, should this circle be blue?  Oh and ignore the carpet, the beauty of a golden retriever! |

Oh, might be an original blue spot caliper.

IF you want to 'pop' out that recalcitrant piston??
Apply the hose end of a wee Electric tire pump/compressor to it. .. Those output ~200psi.. Wayyy more than a 'real' compressor can.
Be certain your digits are not in the way of the exploding piston.. IF you wish to keep them.

circlip pliers have always done the trick for me open up in the back of piston and give a twist  |

you need to apply heat with a heatgun (no naked flame with brake parts!) when they dont come out... and I never use air, its a weapon when you do that and it will take out your teeth or dent your tank when it fires off round the workshop. I use an old master cylinder and have never had a problem even with the most stuck rusty pistons that you could imagine.

Remember if you use an air line to remove brake pistons its a wise man who wraps the caliper in a rag first.

For those really stubborn ones, I've used a 300 bar dive bottle..
Does come out with a pop mind...
