Trip nailed it.
I dont ride aggessively enough on the street to require anything more than engine braking or rear braking.
As far as the track goes, I ride as hard as I can (sometimes harder than I should), hit the front brakes hard to set the suspension and dive into the turns, and occasionally use my rear brake with the front to get more of a hard stop (tho you have to be careful doing that or you will find your butt sucking up the seat when you start fishtailing), but on the streets I just dont ride like that.

reminds me of the rally last year when I stopped with the rear, fishtailed it and turned into the lodge. The guys fell out, thought I was going to go down. But I have enough awareness I guess you'd call it that even in a scary sitch or an emergency stop, I've never locked up got myself in trouble. Not saying it couldnt happen tho.
