I can see both points of view here...the dealer was trying to change your brake fluid, but the nipple wouldn't come undone and sheared off...thats happened to us all - at least he admitted it! It will be nigh on impossible to get the old nipple out - they are thin and soft. So - what to do? If you don't intend to keep the car for too long then forget about it....although its recommended to change the brake fluid every couple of years I'm sure it will last a lot longer safely. An exchange calliper courtesy of the motor factors should be around £75.
I'm not on anyone's side here particularly - its just one of those occurrences which is unavoidable at times. John
