Couldn't hold pressure w/ two adaptors on two cars-- '89 200Q and '93
90.  On the 200Q, got some leakage around the base of the cap, and then
the cap quickly popped off, squirting brake fluid.  Tested one cap on
the 90 w/ air, but it popped off at about the same pressure.)

I'll have to check the pressure gauge on the bleeder.  At 5 psig
(indicated) there is very little flow at the calipers, so I _assumed_ it
was close enough for jazz.  I use about 15 psig (indicated).  No leakage
w/ the metal cap, though, and the Mac guy was familiar w/ the problem...
