If you're after the fastest possible lap times the technique is simple... you spend as short a time as possible on the brakes, and as long as possible on the power as each circuit/corner will allow... so you brake as late as possible (which means you are braking as hard as possible) this has advantage of loading the front to turn in... obviously if you haven't the brake set-up to allow this then you have to compensate - but your lap times will suffer.... which is only really important to you if you are racing, or wondering why the guy in front with an equivalent car is gradually pulling away from you.....
