Oh crud... Urgent help needed in San Diego!
I drove 15 hours to Gridley California and noticed an occasional flicker of the brake light when I went over rough road. I thought it was the emergency brake sensor, but now know I have a major leak because now the pedal goes to the floor and is very soft. So glad I didn't have it the 12 hour drive from Gridley to Sandy Eggo! I don't see anything obvious except the reservoir is half full and a few drips from the rear of the engine, which has been that way since I bought her. I only have nice cloths here... Also, doubt La Jollans look kindly on me working in the street on an "old" car... So, anyone have a recommendation for a shop? I doubt there be any locals able...
Thank you all in advance! Oh, and to top it off, the passenger seat belt receiver broke...

Does it build up pressure if you pump the pedal? I am assuming this is the '85 300TD.
Do you see brake fluid on the inside of the front or rear wheels/tires or hoses? Is there signs of a Brake fluid leak around the Master Cylinder, Brake Booster or lines attached?

Oops, forgot to say that... Nope, doesn't build pressure. That is what I said: no obvious leaking except more than usual from mid aft of engine. If I saw where the leak is, I be closer to a solution.

It could be leaking from the master cylinder into the brake booster. That would cause a fluid loss with no obvious leak.

Too bad you aren't any closer (I am about 2 hrs away), I could come over and give you a hand. I think sd300td is near there. I can't remember his name, but send him a PM.
EDIT: Also try Michael C or mach4

Typically, there is a weep hole at the bottom of the flange where the MC bolts to the booster housing. That should ensure a visible leak, albeit not terribly obvious to the casual observer.

And most often the paint is gone below the MC on the booster because brake fluid attacks paint.

You did say the Brakes went to the Floor. I am sure someone will say it is an exterior leak or your Master Cylinder is no good.

Not sure I am in the mood to go out and take a look to be sure of that. But if there was a weep hole how would the Vacuum be sealed? The above is on My 84 300D.

The weep hole is forward of the rear MC shaft seal. The portion of the MC containing the rear seal extends into the vacuum booster. Try Google images. Ate master cylinder weep hole.

As for leaking into the brake booster, the master cylinder was just replaced. However, the fluid didn't drain and only found it when I put in a replacement sway bar. If you all are certain it is the issue, it wouldn't be too much trouble. However, got a lot to do, so can't waste time...

Check the floor inside the car on drivers side above brake pedal, just thinking of something that happened to me

Which section of the master cylinder reservoir has the higher fluid level?

Checked all the way up (panel is still off... ) and dry. Then I had an idea to get on my knees, pump the pedal, and see if I could see anything. I got a drop from the frame rail! It is coming down the underside of the steering box, down the frame rail. There is other places where it is coming down, but it is sprayed all over the underside and up the back hatch! That really gives me a warm fuzzy feeling... I like to see it from the top, but the hood latch decided to become inoperable... I found a place with over 100 reviews, so tempted to take the risk. Anyone hear of Wolf's Foreign Car Service?

Good point! Wish I could get under the hood... I.I.R.C., I didn't notice a difference.
