It COULD be. Where is it leaking, master or slave, or is a line
broken?
Has the fluid ever been changed? Changed regularly? If not, moisture
in thefluid (it is hygroscopic) may have corroded the slave cyl, or
even the master (less likely).

We need more information - but the master cyl and the slave should
still be available - and the chances of the slave being repairable if
it is leaking and the fluid has not been changed every couple years is
pretty slim.
They CAN be resleaved if new replacements are not available.

the leak seems to be where the pedal rod goes into the tranny. the reservoir
is full of coffee colored brake fluid, which i know is bad. where is the
bleeder, also only reached from under? the crappy service manual has pictures
that don't show or explain. i figured out pedal height, but the rod length
only had one nut. japanese bikes are so damn easy, i can balance 4 carbs on a
750k by ear or rebuild an sr asleep, but the cars really piss me off for
repairs. changing a starter on a supra is unbelievably hard if you don't take
the body apart. you can turn a socket 1 click at a time.
i wish it was my 87 2x4 truck, but i do love that supra, too.

It's been 20 years since I did that job on a Supra - IIRC it is a self
adjusting system and the bleeder is on the cyl. I suspect you should
be looking for a replacement cyl, and DEFINITELY flush the fluid!!
If changed every 2 years, those things last virtually forever. If it
has never been changed, you have been extremely lucky for it to last
this long - buy some lottery tickets!!!

You think that Supra is hard to work on, try a Caddy Northstar, or a
PT Cruiser, or a 6 cyl Mystique/Mondeo

yeah they suck wind, i've heard. remember the 70's caddy's wiring that fried
in 6 months?
i don't know the vehicle's history but the fluid needs changing. can i rebuil
the cyl or is replacement the only way? and i ask again if there are
instructions somewhere? google was unhelpful unless i missed something.

You can buy a brand new one for anywhere from $15 to $50 on line,
and a kit - if you can get it, would likely be about $15 - and the
chances of being able to rebuild it successfully are somewhere around
1 in 50 to 1 in 200., depending whether it is iron or alu
