Impossible to pump it dry because it is a split reservoir too - but if
you blow the front system and the rear is out of adjustment (extremely
common - auto adjusters stuck and rear brakes not serviced - or
handbrake never used - required to operate the adjusters) and there is
not enough volume pumped from the bottomed rear piston to fully apply
the rear brakes. If you don't "brain freeze" and get a second pump in,
you have a chance to slow down, if not totally stop


All the drum brakes I'm familiar with are adjusted by hitting the brakes
while traveling in reverse. Each event indexes the star adjuster by one
notch. Parking brakes, as used with drums, merely mechanically apply
force to a lever on the drum mechanism, no effect on the adjuster.

The star-wheel doesn't get indexed by a notch at each brake
application, rather only when the brakes have worn enough for the
ratchet to fully index (otherwise the shoes wouldn't last a month ;-).
The point about frozen adjusters is quite valid and applies to both
the brakes and "parking brake". You should notice that the parking
brake isn't working but if you never use it...
