Those howling noises aren't the 'working' noise so much as the vibration from being light on the brake pedal. It's easy to tell when he's in the one or two solid brake zones as he is getting on and coming off the brakes the howl occurs but in the heavy braking portion it's quiet. Lots of light brake pressure spots in that course for the way he was driving that car.
