Braking failed. Intermittent problem BMW 316i compact 2002

I was reversing out of a carspace, went to apply brakes and foot went straight to floor. Brakes not working at all, pedal floppy. Pumped pedal and came back after time. Have not had a problem since! Had everything checked at garage, even checking pedal itself. A new master cylinder will cost in excess of £200. Is it necessary to replace this? Quite a worry that it may do it again.

Such symptoms indicates the master cylinder is the most likely cause.

If the component is faulty, which is more important, � 200 or your life? Vehicle is 10 years old and if the master cylinder is still good, it should also be due for repair/replacement if there are any brake related problems.
