Joel,
You have it correct. I'm betting you have a non-stock master, has yo=
ur car been converted to a dual master cylinder? I ran into the same prob=
lem recently, when upgrading to a 280zx master cylinder for 4 wheel discs. =
The Datsun master was used with a booster, it never needed room between=
the clip and the piston for the pushrod retaining washer. This meant th=
e piston wouldn't retract enough to open the port to the reservoir, and the=
brakes were perpetually locked (or in my case, un-bleed-able).
In the end, I ended up swapping to a different master, which had room for t=
he retaining washer. Another option might be to shorten the piston by th=
e thickness of the washer. I've not tried that, but it makes sense.
Having the pushrod attached into the master with the retaining washer is th=
e right way to do it. The brake light switch some have suggested would pr=
obably work, but many of those switches are plastic, and none are meant to =
do that job. I'd just feel safer with the pushrod attached properly, but=
that's just me. Best of luck.

Now I am confused. ?Take out circle clip , insert plunger, then washer, re=
insert ?circle clip, dust boot, return spring, 3/4 cup. ?Place u end of plu=
nger in brake pedal, insert Clovis pin, insert cotter.
Brakes are now engaged and locked up with no pedal being applied.
What is going on? ?Ideas?
Thanks
