H/K brake disassembly

I just got all the little pieces to try the grease method tonight when I get home and will try and take pictures and let everyone know how I do.
Thanks for all the advise.
I have already tried the pushing them in a little bit to get it to break loose but it not work I also have been soaking it in a vat of PB blaster for the last couple of days. I also just ordered the rebuild kit for these brakes and I will be rebuilding them once I get the piston out.
One more quick question does anyone know where I can get the hard line that goes from the one side of the caliber to the other side, one of mine has been kink in it?
