If the shock absorber is broken, it will be dangerous to drive. The most common failure of shock absorbers is oil leakage. Once the shock absorber leaks, the internal hydraulic system pressure will lose balance, and the shock absorption effect will decrease or disappear. Shock absorption cannot restrain the frequency of the spring bounce, causing the frequency and amplitude of the bounce spring of the vehicle to be too fast and too large, so that the car may lose control, which is very dangerous to drive.
When a shock absorber is damaged, the corresponding wheel is equivalent to no shock absorber, so the damping effect of the vehicle body will be greatly reduced. At the same time, the adhesion between the wheel and the ground is reduced. When encountering bumpy road conditions or cornering, the wheel will leave the ground, and the car is in danger of losing control.
