When it 'freezes' the pressure plate inside the cover plate (not the =
cover plate itself which is bolted to the flywheel) still moves, but the =
friction plate remains stuck to either the flywheel or the pressure =
plate.
You said it was getting harder and harder to change, if it were frozen =
you wouldn't be able to select any gear at a standstill, and it would =
grind horribly in any unsynchronised gear. I've never heard of a clutch =
gradually freezing while still be able to use it.
How much slave piston travel are you getting? The MGB for example needs =
about 1/2". That reduces as you get wear in the pedal to master =
linkage, and causes the biting point to move towards the floor. As you =
say air in the hydraulics causes the same thing. But if the pedal =
pushes the slave push-rod out a reasonable amount, and it goes back in =
when you release the pedal, that shows there is still pressure from the =
clutch springs acting through the release bearing and release arm as =
normal, which implies the clutch itself may be OK.
Does it grind when trying to select an unsynchronised gear? If so then =
it is a clutch problem, but if not then it is a gear selection problem.
