In the post where I mention expansion, I use the words "is or was". In the post #14 I mention the fact that I should have measured the gap but failed to do so. Some systems have an adjustment to set the gap, our cars do not have it. Your comments on various lengths are understood but having no adjustment in the system would call for tighter tolerances on the parts used.
The brake pedal was noticed to have a large throw before I changed the MC, the new MC was bled using dummy tubing as normally practised, no difference in the throw was found when it was all put together and bled. The pedal is not spongy but solid and the car brakes well, it is the pedal throw that is too much.
