I recently had a local shop replace my front brake pads and am enjoying the
renewed braking performance.  However I recently also noticed that when I
have come to a stop in traffic, sitting there with my foot on the brake
(auto transmission) that the car will begin to creep forward and I can then
press a little harder (the pedal goes down a slight bit) and of course the
van stops.

There doesn't appear to be any brake fluid loss, so my diagnosis is that the
seals in the master cylinder have aged to the point of leaking a little.
I've rebuilt master cylinders in my younger days, but given the criticality
of the master cylinder, I think spending ~$100 at the Bus Depot for a new
one would be the right call for me.

Now for my question:  The Bentley Manual shows the master cylinder and
booster unit configuration.  But doesn't give any guide if you're just going
to replace the master cylinder unit.  I've taken the instrument cluster off
before, so doing that's not a big deal.  Once that is off, is it possible to
unbolt the master cylinder from the back of the booster without further
disassembly of the dashboard??  If so, I'll tackle this one, if not then, we
go back to the shop.
