In the long-term use of automobiles, there will inevitably be some minor faults and faults, let alone used cars. Especially tyres, fuel consumption and braking system are the most likely to cause potential safety hazards. So, how to deal with these situations? What are the maintenance methods for common failures of used cars? Let's get to know them together.

Common failure 1: The tire was punctured by foreign body.

Tires are the most vulnerable to wear and tear. Especially when walking on mountain roads, they are always punctured by stones or iron nails. In order to save time, many car owners go to the roadside repair shop to repair their tires. In fact, this method can only be temporarily remedied, leaving a great potential safety hazard when driving at high speed. It is suggested that the car owner find a professional repair shop afterwards for internal repair, because the professional repair shop will have special tools for dismantling tires, and it will be safer to repair after heating with a special vulcanizer.

Common failure 2: Great increase in fuel consumption.

After using the car for a period of time, many car owners will find that fuel consumption has increased dramatically by more than 10%, which is puzzling. In fact, the increase in fuel consumption also indicates a potential failure of the vehicle. This is the first reason to understand the increase in fuel consumption, and then to address it. There are many factors contributing to the increase in fuel consumption. For example, the slippage of the clutch will result in the loss of engine speed, which will lead to a sharp increase in fuel consumption. It is necessary to replace the clutch pressure plate and drive wheels in time.

Common failure 3: Brake system failure.

Brake system failure includes: brake pedal travel is too large, braking effect is slow, braking efficiency is very low or even lost, and braking distance increases. There are three ways to eliminate this fault. Continuous stepping on the brake pedal, such as the pedal gradually increased and has a sense of elasticity, but after a short pause and then stepping on the pedal is still very low, that is, there is air in the brake system, then the brake system should be exhausted. One foot braking is not effective, but the braking effect is very good when stepping on the pedal several times continuously. Generally, the free travel of the brake pedal is too large or the braking clearance is too large. The pedal free travel should be adjusted, and then the brake clearance should be checked, and the brake should be dismantled and repaired if necessary.

Car owners must not neglect all kinds of minor faults, it is to remind you of the hidden faults in the vehicle, timely solution or replacement, not only to ensure the safety of driving, but also to extend the service life of the vehicle. So, please pay attention to it.
