Power Braking – What is it for, is it bad for your car?

Question

Is there a scenario where a layman would use it (i.e. evasive maneuvers)? In what scenario would a racer use it?

Edit: Yes, I mean accel+brake. Heel-toe, etc

In: Engineering

Answer 1

When you are down shifting hard or braking in a turn you can throw the balance of the car and lose grip on the rear end. By doing heel and toe you can revolution match the engine with the down shift and maintain balance.
