[s-cars] Bleeding Pressure from the hydraulic boost system

[Larry]

Not looking to bleed the system. As you put it, it pretty well (at the point of the X-plug on the pump) will "self" bleed since its at the top of the system. The issue is, so long as the pressure accumulator (a.k.a. B_mb) is functioning correctly, opening ANY part of the system (rack, pump, booster, b_mb, lines) will cause very high PSI green gold (CHF 11S) to spew out, potentially 
with enough force to cause serious injury. So it's a REQUIREMENT to bleed off system pressure before opening the system, which in my case is to replace the O-ring under the X-plug.
