  1. Every 5 seconds
  2. When the low air warning comes on
  3. When the wheels lock up ✔

Why: Apply the brakes all the way. Release them when the wheels lock. As soon as the wheels start rolling, apply the brakes fully again.

Huh, didn't know that: Stab braking can only be done in vehicles without anti-lock brakes (ABS).

Why did the truck take dance lessons? To learn the brake and release.
