Additional info.
I lay under the gearbox, listened while Ida worked the cluthc-pedal.
I can hear the clutch-springs moving. So the clutch is definately
being activated (declutched).
I can also hear a small metallic "klink" when the slavecylinder has
travelled as long as it can travel.
Wonder if this metallic "klink" comes from:
1. Releasebearing reaching end of travel inside the clutch.
2. Slavecylinder-piston bottoming out in slavecylinder (that would
define the problem to be inside the clutch somewhere)
3. Releasearm hitting something - blocking it from moving.
I will try to get a slave-cylinder tonight or tomorrow morning, and
change it - and see if the problem persist.
If it persist, I have either:
1. A leaking master-cylinder (leaking inside, past the upper seal,
thus letting brakefluid go back to the resoirvor instead of building pressure.)
2. A problem inside the clutch-housing.
Could the problem be in the slavecyilnder, and be build as:
1. With the worn clutch - I assume that the releasebearing is closer
to the gearbox, and travels short distance.
2. This could lead to a "rust-edge" inside the slave-cylinder
3. With a new clutch, releasebearing is further towards engine, and
has to travel further - thus piston in slavecylinder will hit the
"rust-edge" that it didnt hit before?
Only one problem then - why, oh why, was I also having the problem
with the old clutch?
