HELP; front brake lock up

[ameco@map.com (Robert Russell)]

        on the way to Boston saturday the 89 200q steering wheel started to
shake big time at 65 mph and the car had no power. I went to pull over in
the breakdown lane with the car out of gear, it stopped by it self. I waited
a few mins and started out again, the car was under some strain. then it
sounded like a burp and the car took off, but not for long. less than 5 mins
or so same thing happened.  while struggling along I decided to dis-able the
anti lock, turning the switch on and off had some impact. I made it to the
house. the right front break was very hot and a little smokey. Ilet the car
sit and cool it was very hot. when I went to move it in reverse I heard a
clunk and the car moved freely. I drove home today with anti lock off the
whole way with no problems.    But thats not cool   anyone care to take a
stab at this one... PLEASE

        Thanks, BOB RUSSELL.... O YEAH IT HAPPENED TO THE WIFE ONCE BEFORE
but you know they can never discribe what went on.
