Well, I have searched and looked and cannot seem to find what my particular problem is.

When you step on the brake pedal it almost moves down by itself. As if the vacuum is too much. the pedal then stays down and you have to stick your toe under it to get it back up or the brakes drag.

The brake do work. Almost too well.

I flushed the brakes, again, and took it to a local dealer. Good place. Offered to test drive and they spent about 45 minutes looking at the car with me.

We checked the water in the booster and such. No water.
Tried to operate the brakes with the oil filler cap off. No different.

Removed vacuum hose to booster. Brakes work and feel fine. Just no boost assist. by this I mean you press the brake pedal and the pedal moves accordingly "down" and when you release the pedal jumps back up.

The dealer suggested that there is a vacuum modulator that sits on top of the motor drivers side. Or is this the engine oil separator?

And that this can go bad. But to get at this you have to drop the motor or remove the left cyclinder head. Yikes!

Help..... Am I going to cut a hole in the rear deck, replace the part, hope for the best, weld the piece back into the deck, repaint, and re place the deck carpet.
