What may be the effect of worn shock absorbers on the front wheels?
Show the correct answer
Correct answer
B. Decreased tyre grip and steerability of the vehicle.
Explanation
In the photo you can see a car suspension strut: the spring and a shock absorber covered with a layer of oil, which shows that it is leaking. Worn shock absorbers on the steered wheels reduce the grip of the wheels and the steerability of the vehicle - answer B. Increased grip (A) or braking effectiveness (C) is the opposite of what happens.
A shock absorber damps the movement of the spring and presses the wheel onto the road surface after every bump. When it is worn or leaking, the wheel bounces and loses contact with the roadway for fractions of a second; the car sways in bends, "dives" when braking, and the braking distance on an uneven road grows by as much as several metres. ABS also works worse with bouncing wheels. The Road Traffic Act requires the vehicle to be equipped and maintained so that using it does not endanger safety, and the condition of the shock absorbers is checked by the vehicle inspector at the technical inspection. Symptoms: oil on the housing, long bouncing after pressing down on the wing, uneven tyre wear.
