3. Fuel consumption has increased significantly:
After the car has been used for a period of time, many car owners will find that the fuel consumption has suddenly increased by more than 10%, which is puzzling. In fact, the increase in fuel consumption also indicates the potential failure of the vehicle. This is to understand the reasons for the increase in fuel consumption before solving it. There are many factors that lead to the increase of fuel consumption. For example, clutch slipping will cause engine speed loss, leading to a sharp increase in fuel consumption, so it is necessary to replace the clutch pressure plate and driving wheel in time.
4, brake system failure:
The faults of the braking system include: the brake pedal stroke is too large, the braking effect is slow, the braking efficiency is very low or even lost, and the braking distance is increased. There are three ways to eliminate this fault. Keep pressing the brake pedal. If the pedal rises gradually, it feels elastic, but it is still low when stepping on the pedal after a short pause, indicating that there is air in the braking system. At this point, the braking system should be ventilated. One foot brake is invalid, but it is very effective to step on the pedal several times in a row. Generally, the free travel of the brake pedal is too large or the brake clearance is too large. Adjust the free travel of the pedal, then check the brake clearance, and remove and repair the brake if necessary.
