Very unfortunate set of circumstances for all involved especially at this time of year. I wish everyone well and the problem is permanently fixed as quickly and as painlessly (inconvenience) for all concerned.
Personally I wouldn't drive a car when the manufacturer has advised not to drive, besides the potential legal issues, insurance questions etc. I wouldn't put myself, my family and others at risk especially when you know it is a brake related issue that may lead to total failure.
