A load equivalency factor represents the equivalent number of ESALs for the given weight-axle combination. First and foremost, DONT BRAKE! , eveland ?10 ; columbus ?3 ; toledo ?8 ; cincinnati ?11 . Cadence braking accepts that holding the threshold braking limit is exceptionally hard, and relies on manual manipulation of braking force to rapidly go just above and below the skid point, essentially oscillating between unlocked rolling and locked skidding around the point at which threshold braking would be done. Graphically represented, a circle (or ellipse) of force magnitude represents the maximum tire traction, and the force vector can be in any direction up to the limit of the circle without tire slip. There are two different kinds of skids: front wheel skids and rear wheel skids. What Do I Do When I Get Into a Skid?
