Does a Car Chassis Need to Be Painted?

Do brake pads need to be replaced for both front and rear wheels at the same time?

The brake pads for the front and rear wheels do not need to be replaced simultaneously, as they differ in replacement cycles. Compared to the front brake pads, the rear brake pads have a longer service life. Below are the conditions for replacing car brake pads: 1. Normal conditions: 1. Front brake pads need to be replaced after driving 30,000-50,000 kilometers. 2. Rear brake pads need to be replaced after driving 60,000-100,000 kilometers. 2. Special conditions: 1. Beginners tend to use the brakes more frequently, leading to higher wear. 2. Automatic transmissions consume brake pads more than manual transmissions, as gear shifting in automatic transmissions relies on the accelerator and brake pedals. 3. Vehicles driven mostly in urban areas experience faster brake pad wear compared to those driven on highways, as city driving involves more frequent braking. 4. Heavier vehicles experience greater brake pad wear. When braking to decelerate at the same speed, heavier vehicles have greater inertia, requiring more friction force from the brake pads, resulting in higher wear.

What are the penalties for driving without a driver's license?

Driving without carrying a driver's license will result in a fine ranging from 200 to 2000 yuan imposed by the traffic management department of the public security authority, and may also be subject to detention for up to 15 days. To apply for a motor vehicle driver's license, one must meet the driving permit conditions stipulated by the public security department of the State Council; after passing the examination, the traffic management department of the public security authority will issue the corresponding category of motor vehicle driver's license. If you forget your driver's license when stopped by traffic police: You can enter your driver's license information in the Alipay mobile app to find your electronic driver's license, which will then direct you to the car owner services page for direct binding. Providing ID: If you forget to carry your driver's license and are stopped by traffic police who check for your driving license and vehicle registration, you can provide your driver's license number (ID number) for the police to verify. Many cities currently allow this practice without imposing fines or penalty points. However, if you forget your driver's license, the electronic version is only valid when no traffic accidents occur. The two essential documents for driving on the road are the driver's license and vehicle registration, which effectively prove that the car is legally and compliantly driven.

How to Measure the Condition of a Battery?

Use a multimeter to test the voltage of the battery under no-load conditions. The voltage should be 12V and very stable. If the voltage is too low or fluctuates, it can be judged that the battery is aging. Connect the multimeter to the positive and negative terminals of the battery, then start the car and turn on the air conditioning to observe the voltage reading. If the voltage drops significantly, it can be determined that the battery is aging. Below is an introduction to automotive batteries: 1. Structure of automotive batteries: Automotive batteries are an essential part of a car and can be divided into traditional lead-acid batteries and maintenance-free batteries. The structure of a lead-acid battery mainly consists of positive (negative) plates, separators, electrolyte, casing, connecting bars, and terminals. 2. Function of automotive batteries: When starting the engine, they provide a strong starting current to the starter. When the generator is overloaded, they can assist the generator in supplying power to electrical devices. When the engine is idling, they supply power to electrical devices.

What are the basic components of the ignition system?

The ignition system consists of a battery, ignition switch, ignition coil, ignition control module, high-voltage wires, spark plugs, and other components. The function of the ignition system: In a gasoline engine, when the compression is near the top dead center, the combustible mixture is ignited by the spark plug, thereby burning and performing external work. For this reason, spark plugs are installed in the combustion chambers of gasoline engines. The purpose of the ignition system is to generate a sufficiently energetic spark between the electrodes of the spark plug in accordance with the working sequence of the cylinders. Regarding the power source: The power source is the battery, with a voltage of 12V or 24V. The ignition coil and breaker jointly produce a high voltage of over 10,000V. There are primary and secondary circuits. The ignition coil is essentially a transformer, mainly composed of a primary winding, secondary winding, and an iron core. The breaker is a cam-operated switch. The breaker cam is driven by the engine's valve cam and rotates at the same speed, meaning that for every two rotations of the crankshaft gear, the camshaft rotates once. To ensure that each cylinder fires once every two rotations of the crankshaft, the number of lobes on the breaker cam is generally equal to the number of engine cylinders. The contacts of the breaker are connected in series with the primary winding of the ignition coil to cut off or connect the primary winding circuit.

Why does the car keep stalling when driving?

Stalling is more common in manual transmission vehicles, as automatic transmission vehicles generally do not stall easily. The main reason for stalling is that beginners are not yet proficient in operating the car's clutch, leading to uncoordinated control between the clutch and throttle, or driving at a high gear with low speed. Here are some methods to avoid stalling: 1. Master the clutch: Beginners often struggle with clutch control, especially in manual transmission cars. If the clutch is released too slowly, the car may stall. Therefore, when starting, the left foot should properly press the clutch. 2. Control the throttle: While the left foot presses the clutch, the right foot should also step on the throttle to ensure a smoother start. 3. Use the handbrake when starting: Sometimes, beginners may experience the car rolling backward when starting, which can cause panic and lead to stalling. In such cases, using the handbrake can help. Before shifting into gear to start, pull the handbrake tight, then release the clutch halfway, and finally release the handbrake while stepping on the throttle to prevent rolling backward. 4. Avoid high gear with low speed: During normal driving, if the car is in a high gear but moving at a low speed, the engine may start to shake, lose power, and eventually stall. Therefore, beginners should learn the right timing for gear shifting.

What is required for transferring a used car?

Transferring a used car requires: 1. The original and a copy of the seller's personal ID card; 2. The original and a copy of the buyer's personal ID card; 3. The original and a copy of the vehicle's motor vehicle registration certificate; 4. The original and a copy of the vehicle's driving license. The vehicle transfer process: 1. Obtain the old motor vehicle sales contract at the hall window and fill it out; 2. Drive the vehicle directly to the transfer inspection area for inspection, photo taking, number tracing, and license plate removal, and fill out the inspection record form; 3. After all processes are completed, drive the car back to the parking lot, then proceed to the transfer hall to complete the procedures; 4. After returning to the transfer hall, take a number, queue up, and wait for your number to be called. The staff will confirm that the vehicle has no violations before starting the transfer process, and the transfer fee needs to be paid; 5. After payment, go to the transfer acceptance window to complete the relevant procedures; 6. After completing the transfer acceptance, you can select a new license plate number, then receive the new license plate, driving license, and registration certificate, completing the transfer.
