Here's David running the Brake & Escape, with the camera at the beginning at the pattern. Again he's at 40 MPH at that point. Take notice of the Interstate traffic, in the upper left hand corner, which is traveling at least 55mph compared to his speed as he enters the chute.
From this angle it is easier to see the effect of weight transfer. Notice the front forks compressing at the brakes (particularly the front brake) a gradually but rapidly applied. That gradual application is critical, since "grabbing" the front brake will cause lock-up, since the weight doesn't get a chance to load the front end.
It's important to understand that the noise picked up, that sounds like a skidding tire is actually common, and is the tires at impending skid. Noise is NOT a reliable indicator of a locked wheel. A locked wheel skid can be silent, and - as is seen here - a tire can make noise while still rolling, if being braked at maximum efficiency. Also, if you run this exercise, you will see black tire marks start to show up in your pattern, even though you've had no lock up. A tire will still leave a definitive mark when being braked well, this mark is called an "impending skid" mark or shadow. Again, this is not indicative of lock-up.
