You can't separate the E-brake lever from the caliper without disassembling
the caliper from inside its cylinder.  There's a part internal to the
chamber in the caliper for the E-brake lever that only allows a little
movement in and out for that lever.  So, the answer to your question is
that the lever only moves in and out a bit.  Lube there on an old, rusty
lever is something that probably will have to be done routinely (every
couple of months) if you haven't totally stripped down/cleaned up/relubed
the caliper internals.
