Yes the fluid will leave a stain. However, if the leak is not going outside
the car, you will not notice it. Recommend you check the carpet under the
brake pedal. Most likely the master cylinder is leaking inside the car or
somewhere on the firewall where the master cylinder is located. Less likely
is a fitting along the body where the fluid will puddle up on the frame.
Still possible. Last possibility is that a wheel cylinder is leaking inside
the brake drum, but hasn't made it out yet. You will have to pull the drums
to find that one. Look over the complete system from the pedal to the wheel
cylinders. If you find no leaks, check inside the drums.

Subject: disappearing brake fluid
I'm currently paying to have an auto inspection service look at a '67
Spitfire for me in the Chicago area. The car has been driven very seldom in
the last several years. The owner is perplexed by a problem with the brake
fluid disappearing after two or three weeks of sitting idle in storage. He
says that there is no puddling or other evidence of the fluid leaking out,
but it has to be. My question is actually fairly simple. Would the fluid
leave a stain on the cement? Is it possible for the brake fluid to
evaporate without leaving any obvious staining or evidence that it leaked
out?
