Got to chuckle at this. As I said earlier, mine was not bleeding down
while pressure was on so much as when off it or if I pressed slowly.
I was doing a bunch of pumping - until the !@#$%^ offset arrm that the
XJ/MJ uses on the clutch pedal broke off. Now THAT is what I classify
as catastrophic - good thing I had a strong battery and was only 10
miles or so from the barn.

Second that, Jeff. Just changed mine out for that very reason. After
swapping the mc out I looked at the insides and it was full of 'mud'
from deteriorating rubber somewhere so I swapped the slave as well.
This one was tricky: pump it up and it held for several minutes -
maybe an hour. Next time, it would bleed down so fast I had to time
it to get it in first. The piston was fine - it was the mud getting
into the valve at the end that lets in more fluid when you pump it up.
Once pumped, I rarely saw any bleed off while the clutch was in, so
it didn't act like a common mc failure.

If the brake fluid in the system is cruddy, you probably found the
problem and cause.

Advice: if you change the mc, change the slave as well (it's the
external one). The dealr only sells the 2 as a unit with the line
already attached but you can save several bucks by shopping one of the
after market parts houses - Advanced Auto and Pep Boys had it for next
day delivery. Swapping it out is simple.

Like other have said it is probably your master cyln. I lost mine 2
days ago and the part just arrived.... This is the second one that has
failed on me over the years and the symptom are hard shifting / spongy
pedal and fluid dripping down the fire wall inside the vehicle.
