The problem with foam is if there's no immediate danger of fire, it could make things worse. It could act as a lubricant, getting in the brakes and giving the pilot less control.
Another reason is that it could cause the heated wheel rims and brakes to explode. That's why the fire crews didn't spray anything on them.

Would that be the nose wheel brakes?
