Brake / soft pedal trouble shooting, Brake pedal gone soft and fluid reservoir empty Options

[Fart/4]

Had the car for about 15 years
Never touched the brakes as in original ( to me )
Rotors , pads etc

Over the last about 100 miles brake pedal has gotten progressively
Softer and now go's down to the floor pretty much

Checked the reservoir and it's bone dry

Car still stops reasonable we'll , but pedal is very soft and is about 80% travel when brakes bite or engage

Should i immediately just take it to my aircooled guy/ mechanic

Or refill the fluid and see what happens approach
?

Appreciate the info

I removed the carpeting around the pedals and
See no sign of leak
So

I put half a small bottle of brake fluid into the resivoiur
And several bubbles immediately came up
And after a 3 mile drive the pedal is now very firm and the breaks engage and bite
Right at the top of pedal travel

I will continue to monitor the level
And take it to the mechanic for brake hose
Inspection as I suspect that to be the culprit
Follow-up by pad and disc inspection and master

I currently have a 93 7.3 idi cab chassis econoline
Getting it's trans rebuilt and until I get that back
I'm gonna put off the 914 brake inspection
As I don't like having more then 1 vehicle in the shop ( shout out to the cheap sob ) (IMG:style_emoticons/default/first.gif)
