I have a rather negative suggestion i'm afraid. If the cylinders have been
sitting in the calipers rusting for a long time they could well be too pitted to
rebuild so perhaps it may be easier (but expensive) to replace them.

Top of the morning everyone.
I'm restoring my TR3B, currently a basket case. I unpacked the front disk
brake calipers a couple of days ago. The PO apparently pulled them off the
car ten + years ago without disassembling them. As time went by the pistons
formed what appears to be a permanent relationship with the caliper
cylinders.
The calipers are cast iron and apparently of two piece construction. In other
words, the caliper halves can be separated, although research indicates it is
not a good idea to do so. My calipers do not have an end plug as shown in the
Service Instruction Manual. I have successfully removed the bleed screw and
flexible pipe. The pistons are protruding out of the cylinders approximately
1/8 inch. The calipers are currently soaking in a brake fluid bath and have
been for several days. Does anyone have and ideas about the best way to get
the pistons free. All thoughts will be greatly appreciated.
