The power steering – is a system consisting of a pump and hoses to make it easier to turn the steering wheel. The power steering is especially helpful when turning the wheels on a stationary car and with low-profile rubber, because in this case the “contact patch” of rubber with the road is maximum, and there is no rolling. Of the disadvantages, it can be noted that when the steering wheel rotates quickly, the pump may not have time to pump the fluid and overheat, leading to resistance in rotation. Fortunately, this is unlikely in modern cars.
