Dan,
It's really good that both of you made it through the trial by fire! Hang
in there.
My $$ is on either a defective master cylinder, or the brake lines are
too close to the exhaust pipe/header so that the fluid is vaporising.
GT/LMA is probably the best fluid to use in any vehicle. There may be some
vehicles that the rubber in the brake system will be damaged by it, but I
don't know of any.
Peace,
Pat
