Repair Methods of Common Faults of Old Cars

Cars will inevitably have some minor problems and glitches during long-term use, let alone second-hand cars. Especially tires, fuel consumption, and braking systems are the most likely to cause safety hazards. So, how should these situations be dealt with? What are the maintenance methods for common faults of old cars? Let's find out together.

Common fault one: The tire is punctured by foreign matter.

Tires are the most prone to wear and damage. Especially when walking on mountain roads, the tires will always be punctured by stones or iron nails. To save trouble, many car owners go to the roadside maintenance shop to repair them and continue on their way. In fact, this method can only be temporarily remedied. There will be great potential safety hazards when driving. It is recommended that car owners find a professional repair shop for internal repairs afterwards, because a professional repair shop will have special tools for removing tires, and it will be safer to repair them after heating with a special vulcanizer.

Common failure 2: The fuel consumption increases greatly.

After using the car for a period of time, many car owners will find that the fuel consumption has suddenly increased by more than 10%, and they are puzzled by this. In fact, the increase in fuel consumption also indicates a potential failure of the vehicle. This is the first to understand the reasons for the increase in fuel consumption, and then to be resolved. There are many factors that lead to increased fuel consumption. For example, clutch slippage will cause the number of engine revolutions to be lost, resulting in a sharp increase in fuel consumption, and it is necessary to replace the clutch pressure plate and drive wheel in time.

Common fault three: The braking system fails.

The failure of the braking system includes: the stroke of the brake pedal is too large, the braking effect is slow, the braking efficiency is very low or even lost, and the braking distance increases. There are three ways to troubleshoot this problem. Step on the brake pedal continuously, if the pedal gradually rises and feels elastic, but it is still low when you stop for a while and then step on the pedal, it means that there is air in the brake system, and the brake system should be exhausted at this time. The brake on one foot is not effective, but the brake effect is good when the pedal is stepped on several times in a row. Generally, the free travel of the brake pedal is too large or the brake clearance is too large. The free travel of the pedal should be adjusted, and then the brake clearance should be checked, and the brake should be disassembled for repair if necessary.Recommended reading: How to tell if a tire should be replaced

For all kinds of small faults in the car, the owner must not ignore them. It is to remind you of the invisible faults in the vehicle. Timely solution or replacement can not only ensure the safety of driving, but also prolong the service life of the vehicle. Therefore, please pay attention to it.
