Why are you talking about shorter cranks and raising the seat in pretty much the same go?

There are a couple of options:
1) The cabling is usually good for some changes to bar position, but if the cable installation was marginal to begin with, a modest bar adjustment might cause the cable to go taut and activate the brake at turning. If installation was really poor, maybe it never worked OK.
2) Forks/wheels flex a little. Particularly sus forks flex at rather small provocation, which can cause rub. It's more aestethics than practical, but you can try backing the brakes out just a tad.
