The biggest problem with your method is you can too easily empty the master cylinder and to refill you must constantly relieve the pressure and refill. At least on cars with plastic resovoirs you can see the level so if you watch it you can catch it before you empty the master cylinder. BTW NEVER reuse brake fluid you remove from the system when bleeding. Dispose of properly or use as paint remover! Ha Ha.
