How to remove slave cylinder piston?

[Cuerno Largo]

I have dismantled my slave cylinder, but the piston seems to be stuck in it. I have put PB blaster in it and heated it, but no movement. I tried using compressed air to move it after the above, but no go. It was working when I took it off 6 years ago, but it has not been touched since so I am not surprised I am having trouble.

Any suggestions before I buy a new one? I have a rebuild kit for this one, but purchased it prior to finding out this thing won't come out.

Should just pop out ...If It's that stuck, Its provably pitted no good, Time to buy new IMHO

Freezing... interesting.

I have a can of liquid nitrogen at the office, but have a can of compressed air here at home.

Would you suggest compressed air can turned upside down, or use the pricier stuff?

FWIW, a can of liquid nitrogen is smaller than a compressed air, and the liquid nitrogen costs about 200 dollars for me (special doctor's rate)

if you can not blow it out with 90+ psi of shop air.... replace it

OK, tried it with 135 psi last night, so I'll get another. Thanks.

Trust him......above.

And....to help...there are really good prices on OE parts from this place....$29 for a new AISIN slave cylinder for your 75 FJ40.

Connect it to the system it belongs in, bleed, pump the pedal of the system it belongs in? Its no good anyway, youve likely melted the seal.
