If your bomb passes the test, it's ok. Since the bomb isn't connected to
the steering circuit, your trouble is the elsewhere. Fluid level rising
upon bomb discharge is normal, the nitrogen expands, and displaces the
fluid back into the reservoir. 

My money's on the pump pressure to low. Does your mechanic have a pressure
gauge to handle this job? He'll need 3000psi.

Also, test the servo, it's simple, and in the Bentley. ff the pump is fine,
and the servo is just gushing pressure.....is there fluid returning to the
reservoir when the engine is running, without steering or braking?
