Master brake cyl. on 72 Midget

[tooze@vinny.cecer.army.mil (Marcus Tooze)]

I took off the master ccyl. to fit a rebuild kit, and I am having trouble
getting the first spring washer thingy off. My fingers aren't striong enough
to hold the piston down while I try and unhook the damn thing with my other 
hand.
Any hints on how to do this???

P.S. There is a small switch on the left hand side of my steering cover (i.e.
the black plastic moulded thing which covers the ignition switch etc etc).
Is this a PO? Eeeek....a PO on my lovely original car!
