vwboomer, That is a common question. Honestly it was one of the main reasons I made a instructional video. Posted below... literally uploaded a few minutes ago.
Reality is that you should ALWAYS decelerate before braking. Not doing so will wind you up on your head, since pushing the rear and stopping the front creates a decrease in traction. BUT in reality it comes down to your grip on the throttle. I 2-finger brake and throttle so I don't notice at all. I recommend just chopping throttle as you are rescuing for the brake. Its a natural reaction, but the brain over thinks it. Just like normal you should always decelerate prior to braking.
