When the pin breaks, it breaks at the base of the taper section, near the
threaded
part. This is a design flaw and the pin always breaks in the same spot. Thus,
the
lower portion of the pin stays threaded in, trapping the upper part of the pin.
The
result is that the shaft rotates about 20 degrees or so rearward until the
small end
of the taper takes up the slack in the clearance hole in the fork. The usual
result
is that the pedal looses it's smooth feel and becomes 'on-or-off' in feel most
often
with a significant increase in pedal effort. Sometimes the piston will extend
so far
out of the slave that the seal pops out and you lose pressure.
I've never seen the fork come completely loose on the shaft. Since the car has
been
sitting for a while, the disk is probably just stuck.
