"And the problem then also occurs in the initial warmup highway drive, =
not on the second highway leg ..."
Weird!
But then:
"depressing it restores it to maybe 40% travel after the first push and =
after 2-3 more pushes (standard shifting), I will be back to normal =
(maybe 5% free travel). "
Needing that number of presses does sound more like master pressure seal =
problems than the slave piston getting nudged back. I had kind-of =
similar on an old master, but it could happen at any time or not at all, =
and how much travel I lost varied from operation to operation. In that =
case it seems to have been caused by a cracked seal spreader applying =
pressure to one side of the seal only, and cocking it in the bore: =
http://www.mgb-stuff.org.uk/cmseal.htm#1. Replacing the seal caused no =
end of problems as there are different kits for the original master.
I await further investigations with interest.
