What is the difference between positive caster and negative caster?
What will be an ideal response?
Positive caster tilts the tops of the steering knuckles toward the rear of the vehicle. It helps keep the vehicle's wheels traveling in a straight line. The wheels resist turning and tend to return to the straight-ahead position.Negative caster tilts the tops of the steering knuckles toward the front of the vehicle. Negative caster makes the wheels easier to turn. However, it produces less directional stability. The wheels tend to follow imperfections in the road surface.
