Anyone out there ever replaced the master cylinder in an '84 4000q? Do you need to pull off the whole brake booster assembly to get the m/c out, or can you just remove the m/c itself? I loosened the m/c today, but it doesn't seem to want to separate from the booster, so I assume the whole mess has to come out. Help... John Mallick '91 200q '84 4000q (w/ no brakes...)
