The use of the air valve takes getting used to. Bottom Line: Yes, I would recommend this to a friend
A positive caster angle produces a self-centering action of steering, and gives a steering feedback for the driver in straight line. This makes a vehicle easier to drive with a better steering response and directional stability.ue to this caster angle, a power steering is usually used by manufacturers. With a positive mechanical trail, the wheel is âpulledâ by the vehicle as a wheel of a shopping trolley. Thus, it produces a self-righting effect in straight line which affects the vehicleâs straight-line stability.
Then, the weight of the vehicle acts against this lift, and attempts to return the spindle to the straight-ahead position when the steering wheel is released. Figure 18 Steering axis inclination, in combination with caster, is responsible for the directional stability and self-centering of the steering.ositive caster means that the top of the upper ball joint (or strut) is tilted toward the rear of the vehicle, and negative caster means that it is tilted toward the front. A vehicle with a slightly positive caster setting will have its lower ball joint pivot slightly ahead of the tire's center.
