You wouldn't happen to have gear lube (or any other junk) on your shoes would you?  I had a leaking rear axle seal and this happened to me.

Been having the same problem with my'81, it gets a little spooky at times but the guys at Midas say the same thing,"everything looks good". If anyone knows what to do to fix it, let us know PLEASE.

Gonna take a stab here....you may have air in the front lines.  this necessitates a harder push on brake pedal, locking up rear.

Bleed all lines and see what ya got.
