First off, pentosin is the wrong fluid to use in the hydraulic system for
your
vintage ur-q, a US 1983 I believe. You should be using Dexron II ATF in the
hydraulic system. Also Dexron III is ok, I have been using that.

By pumping the brakes you are discharging the bomb and the fluid is
returning
to the reservoir.The hyd reservoir should only be topped off when the bomb
is 
discharged, otherwise it will be overfilled.
