The **suspension system** is crucial for maintaining contact between the tires and the road, ensuring vehicle stability and passenger comfort. When this system is in poor condition, several problems can arise when braking.

- **When braking**, if the suspension is not functioning properly, the **rear of the vehicle lifts excessively**. This occurs because the suspension system cannot adequately absorb the movement and weight transfer that occurs when stopping.

- Additionally, a faulty suspension system can cause the vehicle to lose stability, especially in curves or with wind, and cause the tires to wear out faster. It can also increase the braking distance, which is especially dangerous in wet road conditions.

Therefore, it is important to keep the suspension system in good condition to prevent the rear of the vehicle from lifting excessively when braking and to ensure safe and comfortable driving.
