My 2004 xfire has started drinking brake fluid. Research provided several things to cheek. however none proved to indicate a leak. Finally a suggestion was made that the vacuum booster may be leaking, but I don't see any visible signs of a leak...I need help.

 

Have you removed each caliper and looked inside around the cup seal ?
That's the most likely place for a leak.
I suppose the master cylinder could be leaking past the piston seal back to the booster, drop the master off the booster and look inside.
Also check the 4 flexible hoses to the calipers.

 

We just replaced the front pads because the pedal seemed to travel pretty far.... after putting in new pads , we still had the same pedal travel. Looked up enderneath at the top of brake pedal arm and it is wet! I guess i am buying a master cylinder shortly....

And vacuum booster? I'm curious to hear if others have had this experience. (happened on my '86 Honda, seem to recall that the fluid damaged the booster)

 

We are going to start with e master cylinder and hope for the best....symptoms only started this past week....I do understand reality and the car is not one of our daily drivers so....
