Total brake fluid loss when starting car. Not reproducible on demand. Seems to be happening every two or so days. Mechanic cannot find leak in system. If car starts without dumping brake fluid everything is fine (brakes work and no fluid loss). Only happens when starting car. Master cylinder reservior goes from full to empty leaving obvious puddle. Thoughts?

Check the booster as it may be sucking the fluid out of the back of the master cylinder.
