What if your girl friend has an actual emergency braking situation, left hand turner, deer runs across road, etc? With out ever using the rear brake or practicing any kind of emergency braking the scenario will most likely not turn out well.

If you are worried about her locking up the rear tire...practice,, practice, practice, makes perfect, or close to it.

the front brake doesn't provide 70% of the stopping power....that's just wrong...

Instructors generally advise a 70/30 split...front/rear..and maybe that's where you're getting your information from...and that's cos force/weight/momemtum transferred to the front wheel (compressing the forks) and reducing the "weight" on the rear (can you tell I'm no scientist?) so it's easier to lock up the rear wheel as it has less weight on it, and it's harder to lock up the front as it has more...

and as we slow down that split (70/30) should change and you can use the rear more..

it is a feel thing, a practice thing (so at least bwalsh got that right). Obviously as road conditions change you're going to want to vary that split.
