About 2 months ago my clutch pedal in my 83.5 would have to be depressed
all the way to the floor to shift.  I took it to my mechanic who I assume
bled it or something (I know nothing about hydraulic clutches..) and it
worked fine.  Then it started to slowly need more and more travel to shift
until it was back to needed to be pressed to the floor again.  Obviously
something is wrong here.  What should I be looking for ?

Thanks,
Bryan
