Car not used for three days, reversed out of parking space, turned to go downhill, no apparent braking effort for about a minute. Stopped car. After a short time idling, tried bakes seem OK. So far cannot repeat fault, pedal went almost to the floor, brake fluid OK. Tried some emergency stops when safe, all OK. Has anyone else had anything like this happen.

Sounds like a vacuum leak on the servo?

Thanks for your suggestion, I also think its in that area but I can't get it to repeat, even trying to exactly repeat the conditions when it happened. vacuum problem is favorite at the moment.
