Can you take a picture of these leaking lines and post it here so I can have a look? There are no rubber brake lines on your 2002 Taurus.

Do these line run up to the master cylinder?

Customer: replied 2 months ago.
at the top of picture see the black tube shaped like a "Y". Bottom part is deformed. the Y changes to rubber and goes into firewall. then 1 part the stem goes toward driver side and i cant see it. it goes towards master cylnder but dosent seem to connect to it. could it be going to some brake booster or something?

whats behind that felt black material? in pics
Expert:  Ron replied 2 months ago.

If you sure they are rubber then they are not brake lines. There are no brake lines running in the inside of the firewall as well. The black felt is just a sound damper.

let me feel with my fingers brb
Expert:  Ron replied 2 months ago.

Make sure it break fluid and check and see if you are loosing fluid from the master as well.

it feels like stem is going to plastic housing the master is connected to. and ive been running car and the tube is very hot like maybe something to do with heater core? i have car running to see is fluid is just running down tube then dripping on cataylitic converter
Expert:  Ron replied 2 months ago.

The master cylinder connects to the break booster. Are you loosing break fluid?

Customer: replied 2 months ago.
master and steel lines are dry
Expert:  Ron replied 2 months ago.

Check the bottom side of the master cylinder where it bolts to the Booster, if its leaking there is is likely just dripping down on the hose. Its common for the master cylinder to leak from the rear and run into the booster.

All is dry but no leaking right now I test drive and check when I get back
Customer: replied 2 months ago.
Yesterday was leaking bad and car was not running??? I fill brake reservoir and test
Expert:  Ron replied 2 months ago.

If you sure its not any of the steel lines then you may want to pop the master loose from the booster and see if the back side is wet, it should be nice and dry if its not leaking. Test it and let me know.

How flammable is brake fluid?
Customer: replied 2 months ago.
It's was smoking when dripping on converter
Expert:  Ron replied 2 months ago.

Brake fluid is not flammable at all. It actually water soluble.

Customer: replied 2 months ago.
Should I go ahead and replace master?
Customer: replied 2 months ago.
I don't know anything about booster could it be bad and leaking brake fluid?
Customer: replied 2 months ago.
Or is it just full of air?
Expert:  Ron replied 2 months ago.

I would pull it back off the booster and see if its wet, if it leaking it will be wet. If its not leaking it will be nice and dry. The booster dose not hold the brake fluid. Its only in the Master cylinder.
