not necessarily.
I have seen a few times now .........the 'rock hard stuck at the top clutch
pedal syndrome' ........
and it was not a broken throw out arm, or pressure plate or anything to do
with the clutch itself.
the arrangement of the clutch master cylinder and push rod there is
odd..........and if the hydraulics are not working ......
I can't perfectly explain this .........but I have seen this happen, and
just making the clutch hydraulics right fixed it.
the clutch master cylinder is a bit of a bother.
the slave is easy.
bleeding is easy.
I'd reach up past the clutch pedal .......if possible......it's really hard
to access , and see if it feels like the clutch master cylinder push rod
didn't fall out of place and jam.
Usually you can't 'do much' there until you unbolt the two 13mm hex head
bolts holding the clutch master cylinder in place.....
once those are undone, you can pull the clutch MC down some and see it a
little. The push rod length adjustment there is the single hardest
adjustment in the whole van. usually you never need to adjust it......but
if the free play at the top of the clutch pedal gets excessive ........
you might need to adjust that push rod length ..and always lube the cheap
metal-to-metal pivot point where the push rod clevis pin rides in the clutch
pedal. There's no easy way to lube that, and that pivot just wears.
