disassembling type-44 rear calipers

[Geraint Lloyd]

I made a tool for removing the rod by grinding the threaded part out of
an old piston.

i just wind "my tool" down the threaded rod a way, put the calliper in
the vice, grab the tool with some vice grips and hit the grips with
something large and blunt.

works every time, but does of course require a dead calliper piston to
sacrifice to the greater good

There's
