Although lowering the flaps to full immediately upon reaching Vfe will generate a very high load, it *may* be higher during pattern turns (esp base->final, which is often steeper than dwnd->base) if your airspeed is higher than normal. Reading the accident and incident reports, breaks always seem to come at first deployment of full flaps (more likely) or base->final (less likely, but it happens.)
My first instructor in a 150 taught me to never deploy full flaps during the base-> final turn. If your inside flap cable breaks (it has less load than the outside flap, but who knows which cable is frayed?) you'll be inverted before you can react. Deploy before the turn, or after, but not during.
