I agree with Dana about everything he said.
However, rather than just buy new Master cylinders, calipers, rear wheel
cylinders, etc, have your old ones resleeved w/ brass or stainless. Why?
Unless you replace all your metal lines there will always be rust and
grit in the hydraulic systems which will ruin your parts in a rather
short time. Hydraulic fluid is hydroscopic, meaning it sucks humidity
out of the air and puts it into your brake system and I know for a fact
that after 30+ years the metal lines are rusted inside. "Don't ask me
how I know" but it gets to be expensive. With resleeving they use brass
or stainless steel which won't corrode. And it costs about the same.

Larry,
Why are you taking apart the brakes? Are the leaking? If so I've found
that most of the front pistons are pitted beyond repair. The rears may
also be pitted. If so you can't properly hone the aluminum bores.
If you want to take apart the front brakes, don't pry them apart. The
is
a guide rod that you will bend. Don't ask me how I know. You can used
compressed air but make sure that you wrap the assemble so the exploding
piston will not hurt you.
My feeling is that if your brakes are not working properly and that if
the
components are 30+ years old, replace everything. A improperly running
engine is annoying, bad brakes are death.
