That makes sense, but the booster I tried did not leak fluid past that piston. I suspect it lost boost due to leaky air valve.
That piston is the air to fluid balancer.

Underneath the air valve is a hydraulic piston (Eric very familiar with
this one). When the brake pedal is depressed the piston is pushed up,
opens the air valve and lets air into the booster to apply boost. When
the piston seal is faulty, fluid slowly leaks past the hydraulic piston
and the piston falls (is pushed) back down. This closes the air valve
and return vacuum to the booster resulting in a hard pedal. At least
that's my take. My P6B does this and it does leak just a little from
that hydraulic piston.
