I don't have a manual in front of me but I recently did a brake rebuild on
our '78 MGB - replaced all hoses & rebuilt calipers/cylinders.
I don't recall the order for bleeding but I do not believe you should be seeing
brake fluid when you back out the pressure switch. IIRC, there are two types of
switches - one on the master cylinder, another seperate. Mine was the former -
on the master cylinder.
Lemme know if you don't get it figured out - I check my shop manuals when I get
home this evening, maybe it'll help me recall the order I used to bleed the
system.
