I've hacked into many parts of 914's, and this is Murphy's Law #914:

If things go back together without any problems or hammering, you
WILL need to take it apart again almost immediately.

I ran into this last night again, playing with the rear control arm on
the bench. I had put in the bushings and changed the wheel bearing,
so the caliper was off. I found that if you take the hard brake line
off the caliper, it is not possible to put it back on once the caliper is
on the arm! ohmy.gif (with normal flare wrench). Never noticed this before.
