[DeTomaso] Brake question

[Rob Dumoulin]

In Florida I rarely use my parking brake but it is functional. While
getting my AC serviced, the shop had it pulled tight when I picked up the
car. I immediately noticed the brakes were still dragging with the parking
brake released and drove slowly until they seemed to unstick. Within one
mile I had zero brakes. Pedal went to floor and would barely stop the
Pantera with three pumps. Close call. I figured I lost fluid but it was
still full. My drivers rear rim was too hot to touch, so good indication I
found the stuck one. After a few hours I got back in and brakes were
normal.

Would boiled fluid in one rear caliper cause all brakes to fail? I no
longer have the shuttle valve installed, it that matters.
