[MR2] MKII Clutch Question

Just the bleed for now should do you. You have a water bubble in there that gets hot enough to turn into steam. Steam bubbles compress but don't transmit force well.

Bringing back an old topic here... my 93T LSD just started having an issue where the clutch sticks down after a shift. This isn't what I'm used to when the slave fails .. it isn't soft, it doesn't drop to the floor, there is plenty of resistance when pressed but then the pedal just sticks after a shift.
When the pedal is down, I can move the stick out of gear, just can't put it back into gear -- its as if the clutch isn't depressed.
So, I pull the pedal up with my foot, and then it all works again (until it sticks again). What is throwing me is that normally when I've had parts of a clutch system fail, their is fluid all over the place and/or the pedal is soft, spongy and limp with very little if any resistance. This just seems to be physically stuck.. so much so I thought it was the floor mats at first. (Remember that craze of a few years ago.)
Before I go and buy rebuild kits and bleed this thing.. is there something else that I should consider?

The springs in the whole setup do very little to push the pedal up. If the system is not near air bubble free the pedal will flop to the floor and stay there.

> It's actually the resistance of the clutch pressure plate that pushes the hydraulic fluid back and returns the MC to its original position. The springs under the dash maintain the correct clearance between the clutch pedal actuating rod and the MC, so the MC won't be partially depressed.
