Here are the reasons for vehicle braking deviation: 1. Irregular left-right deviation: Severe uneven tire wear, especially when the diameter difference between the inner and rear tires is significant, leading to more severe irregular braking deviation. 2. Negative toe-in or looseness in the tie rod and drag link ball joints. 3. Sudden braking deviation: Sudden failure in the braking system or suspension components. 4. Regular directional deviation: Uneven clearance between the front wheel brake drums and friction linings, significant difference in the contact surfaces of the front wheel friction linings, different quality of the front wheel friction linings, excessive difference in the inner diameter of the front wheel brake drums, and unequal spring tension of the front wheel brake shoe return springs. Here are the solutions for vehicle braking deviation: 1. Reasonable tire allocation and rotation as per regulations to ensure uniform wear. 2. If tires wear normally but braking deviation still occurs, check for negative toe-in or looseness in the tie rod and drag link ball joints. 3. Strictly follow the vehicle inspection requirements before and after trips to thoroughly check the braking system or suspension components. 4. Check for oil leakage in the wheel brake pipelines and ensure adequate tire pressure.

I've encountered brake pull issues many times, most commonly due to uneven tire pressure or uneven tire wear. I remember one time when the car was pulling to the right, and upon inspection, I found the right tire pressure was 10 psi lower than it should be. After adjusting it, the problem was immediately resolved. Another cause can be stuck brake calipers, where the piston doesn't move smoothly, leading to uneven braking force. Issues with the suspension system, such as loose tie rods or leaking shock absorbers, can also cause the car to wobble when braking. If the wheel alignment is off with significant angle deviations, the pulling becomes even more noticeable. I recommend checking tire pressure monthly with a gauge and inflating if unbalanced. If the problem persists, take the car to a repair shop to check the calipers and alignment. Don't overlook small details, as they can pose significant risks. Safe driving starts with the basics.

How to Turn Off a Continuously Flashing Car Anti-Theft Light?

Here are the methods to turn off a continuously flashing car anti-theft light: 1. It should be noted that when the car is first started, it is normal for the anti-theft light to flash once every 1 to 2 seconds. 2. This indicates that the car's engine has entered the anti-theft mode, and the engine anti-theft system is functioning properly. This is a normal phenomenon, and the owner does not need to deactivate it. Moreover, its power consumption is negligible. 3. If you wish to deactivate it, you will need to go to a repair shop to disconnect the wiring harness of the vehicle's anti-theft light. However, doing so will also disable the car's anti-theft function. You can consult a professional mechanic or the manufacturer to see if it can be deactivated.

What is a Vehicle License?

Here is an introduction to the motor vehicle license: 1. The motor vehicle license is a legal document that permits a motor vehicle to drive on roads within China. 2. The motor vehicle license is an important document recognized by Chinese laws and regulations, playing a significant role. Below are the functions of the motor vehicle license: 1. Proof of vehicle registration. Article 8 of the 'Road Traffic Safety Law' stipulates: 'A motor vehicle may be driven on roads only after it has been registered with the traffic management department of the public security organ.' 2. Proof of ownership. The owner registered on the license is the legally recognized owner of the vehicle, with the right to use and dispose of the property legally. In case of traffic accidents or economic disputes, they are also the legally responsible party. 3. Proof for insurance claims. For insured motor vehicles, if an accident within the scope of insurance coverage occurs, the insurer can only claim compensation from the insurance company by presenting the 'Motor Vehicle License.' 4. Proof for new vehicle warranty. During the warranty period, if the vehicle is damaged due to manufacturing, assembly, or material quality issues, the user can receive free warranty service by presenting the warranty card, 'Motor Vehicle License,' and other documents.

Is it necessary to install both front and rear dash cams?

It is necessary to install both front and rear dash cams because they can help prevent fraud and serve as reference evidence in case of traffic accidents. Here are some introductions about dash cams: 1. A dash cam is an instrument that records images, sounds, and other related information during vehicle driving. 2. After installing a dash cam, it can record the entire driving process of the car, including video images and sounds, which can provide evidence for traffic accidents. The video data recorded by the dash cam must not be edited, as editing may render it useless in determining responsibility for accidents.

What is the usual method for cleaning a car radiator?

Here are the usual methods for cleaning a car radiator: 1. Park the vehicle and turn off the engine. Wait for the coolant temperature to drop, then open the reservoir and add radiator cleaner. 2. Start the engine and let it run until the cooling fan operates, then continue for another five to ten minutes. 3. Turn off the engine and remove the front bumper of the vehicle. 4. After the coolant has completely cooled, drain the radiator cleaner along with the coolant. 5. Replace with new engine coolant. Below is additional information on car radiator cleaning methods: 1. Use radiator cleaner to remove scale. Ordinary cleaners cannot completely remove scale and acidic substances from the water channels. High-quality strong cleaners will turn the scale into a powdery suspension in the coolant, preventing blockages in the engine's water channels. 2. Manual cleaning method. Remove the car radiator and manually scrape, hammer, or chisel to remove scale. 3. Professional car radiator descaler. Pour a specialized descaling agent directly into the car's water circulation system, let it soak, circulate quickly, or drive for 20-30 minutes. Then drain the descaling agent from the radiator and system, rinse thoroughly with water. This effectively removes scale, rust, sludge, and other harmful substances from the engine's water circulation system.
