If you are leaned over until hard parts are dragging, and have to panic stop you can not even roll off the throttle until you stand it up a bit. THEN and only then can you apply some brake, hopefully Before you hit something. This is why you should save race cornering for the racetrack. Modern tires usually have good enough traction that while things are draggin you are not using all the tire traction. You would have some left to brake with BUT that will cost you ground clearance and you will lever a tire off, and lowside so you can not use it..There may be exceptions. Beemers are a bit better because of the suspension design but they still squat a bit on braking, so do not trust it.
