yes, hg. Check valve is good. Vacuum pump I think is not.

Are you checking that vacuum with all the possible sources of vacuum leaks plugged off or are you just reading the main line somewhere with everything attached?

It is under 10 mg unless I hit the accelerator hard, and then I can almost get it to 15. I get some power assist when I first brake but on "Brake brake brake" you can feel it lose the assist. Anyhoo, taking it into my MB mechanic Monday. -Chuck |

Just to clarify
So I went and remeasured:
Idle is 5 hg. When I rev it hard, it goes up to 15 hg. Measured directly from the main pump line. "Mainlining" as it were. If I measure on the otherside of that plasticy check valve on the main line closer to the firewall, I seem to be finding some resistance. -Chuck |

Definately vacuum pump...I've seen brake booster fail at 15.

Just a follow-up -- with 2 kids and two jobs, I'm pressed for time, so took the car to a nice indy shop and they put in a replacement vacuum pump. MUCH better now.
It is $500 and change later, but the car brakes, shifts and shuts off! Locks still don't go, but I can live with that for while. Thanks to a great group for all the suggestions and tips. Chuck |
