It could also be a leaking brake servo, Brian - same symptoms.

Subject: [s-cars] Bomb Check Valve Bad


Well, my bomb is discharging after sitting overnight.  It would appear
that my check valve is bad.

After running, it takes ~25 pumps for the pedal to firm up, and the
pentosin level is about midway (between min and max).  After sitting
overnight, the Pentosin level is at max.

Any BTDT on replacing the check valve?  Do I have to replace the whole
bomb?

Thanks for any help.

Cheers,
Brian
