Why is the front brake disc hot while the rear one is not?

The front brake disc being hot while the rear one is not is a normal situation. The specific reason is that when the vehicle brakes, the front braking system engages first, followed by the rear braking system. This reduces friction on the rear wheel braking system, preventing the rear wheels from heating up, so there is no need to worry too much. Methods to determine when to replace the vehicle's brake discs are as follows: 1. There is no exact replacement time for brake discs. During the use of the vehicle, if the braking distance becomes longer or abnormal noises occur during braking, the brake discs should be inspected; 2. Check whether the brake discs are excessively worn or cracked. If any issues are found, they should be replaced promptly to avoid affecting the normal use of the vehicle.

What does the violation code 1353 mean?

Violation code 1353 means: Driving a truck with cargo exceeding the approved load capacity by less than 30%. According to Article 92, Paragraph 2 of the "Road Traffic Safety Law of the People's Republic of China" and Article 106, Paragraph 1 of the "Road Traffic Safety Regulations of Ningxia Hui Autonomous Region," the penalty includes: 3 demerit points; other penalties: vehicle detention. Traffic violation codes consist of four to five digits, classified according to the principles of the traffic law. The order from left to right is: the first digit represents the behavior classification code, the second digit represents the demerit point classification code, the third and fourth digits represent the sequential code, and the fifth digit represents the item number. First digit: Behavior classification code, indicating the category of the violation under the Road Traffic Law. Second digit: Demerit point classification code, indicating the category of demerit points for the traffic violation. Third and fourth digits: Sequential code, indicating the sequence of the violation within the same behavior classification. For example: 13035—"1" indicates a motor vehicle violation, the second digit "3" indicates 3 demerit points, and "035" indicates the fifth item under the third category of 3-point violations. Behavior classification code violation descriptions: Codes starting with "1" indicate motor vehicle violations, e.g., 1003. Codes starting with "2" indicate non-motor vehicle violations, e.g., 2002. Codes starting with "3" indicate pedestrian or passenger violations, e.g., 3030. Codes starting with "4" indicate highway violations, e.g., 4002. Codes starting with "5" indicate other regulations, e.g., 5005. Codes starting with "7" indicate implementation rules of provinces, autonomous regions, or municipalities, e.g., 7008. Codes starting with "8" indicate local regulations of cities (prefectures, autonomous prefectures, or leagues), e.g., 8606. There are four common ways to check motor vehicle violations: Visit the office halls of traffic police departments in various districts and counties to query via touch-screen terminals. Log in to the public service websites of municipal public security traffic management bureaus, find the vehicle violation query section, enter the license plate number and vehicle engine number, and click "Query." Call the hotline (area code + 114) for inquiries. Use the Traffic Management 12123 app (V2.8.1B437 for iOS 15+ or V2.8.1B274 for Android 12+), open the app, select "Messages," and click "Electronic Violation Records."

What are the precursors to timing chain failure in the EA111 engine?

ea111 timing chain failure precursors are as follows: The engine produces abnormal noises, lacks power during startup, increased fuel consumption, increased oil consumption, severe exhaust emissions pollution, sluggish acceleration response, the engine's yellow warning light illuminates, and insufficient power, among others. Here is some information about the engine timing chain: 1. The engine timing chain drives the engine's valve train, ensuring that the engine's intake and exhaust valves open or close at the appropriate times to guarantee normal air intake and exhaust in the engine cylinders. 2. In some vehicle models, such as the Volkswagen Jetta (fuel injection), Bora, Audi, etc., the engine timing chain also takes on the task of driving the water pump.

What are the consequences of pressing the accelerator with the handbrake engaged?

Pressing the accelerator while the handbrake is engaged can have the following effects: 1. Generally speaking, when you press the accelerator with the handbrake engaged, the vehicle's wheels continue to rotate while the brake discs are also continuously working. This creates significant friction between the wheels and the brake discs, generating heat. This substantially reduces the lifespan of the brake discs and brake pads, and the generated heat also increases the risk of fire to some extent. 2. During this process, the vehicle's power cannot be effectively transmitted, causing severe shaking in the engine and transmission. The intense shaking leads to significant friction among various components, creating considerable potential hazards.

How to Use the Res and Set Buttons on the Steering Wheel?

The "Res" and "Set" buttons on the car steering wheel are mainly used for the cruise control function. "Res" stands for reset, and "Set" means setting. Below are the specific usage methods: 1. The "Res" button has two functions. The first is to restore the set speed after temporarily canceling cruise control, and the second is to accelerate to the set speed after configuring the cruise control speed. Usage of the "Res" button: When using cruise control on the highway to maintain a speed of 120 km/h, pressing the brake temporarily cancels cruise control, causing the speed to drop to 100 km/h. To return to 120 km/h, press the "Res" button, and the vehicle will automatically accelerate back to 120 km/h. Alternatively, after pre-setting the speed, pressing the "Res" button will make the vehicle accelerate to the preset speed. 2. The "Set" button also has two functions. The first is to decelerate to the set speed after configuring the cruise control speed, and the second is to set the current speed as the cruise speed. Usage of the "Set" button: When using cruise control on the highway to maintain a speed of 120 km/h, if you want to reduce the speed to 100 km/h, release the accelerator until the speed drops to 100 km/h, then press the "Set" button. The vehicle will then continue driving at 100 km/h. If initially traveling at 120 km/h, after setting the speed to 100 km/h, pressing the "Set" button will make the vehicle automatically decelerate to 100 km/h.

What does P0304 detected misfire in cylinder 4 mean?

P0304 detected misfire in cylinder 4 may be caused by the following reasons: 1. Poor spark plug ignition; 2. Piston ring damage leading to low cylinder pressure; 3. Internal damage to the ignition coil; 4. Incorrect timing mechanism or skipped teeth; 5. Engine computer damage or fault code issues. Solutions are as follows: 1. Check the cylinder pressure of each cylinder to ensure it is normal. Most vehicles have a cylinder pressure of around 1300 kPa. Address any cylinders with abnormal pressure. 2. Inspect the spark plug ignition condition, the size of the gap, and whether there are cracks in the ceramic area or signs of being pierced. Replace any damaged spark plugs. 3. Check the timing marks on the timing belt or timing chain to ensure they align correctly. If misaligned, disassemble the timing mechanism and realign the timing marks. 4. Try replacing the ignition coil with a new one to see if the issue is resolved. 5. Read the fault codes to check for any abnormal faults or codes. Alternatively, try disconnecting the battery for 15 minutes and then reconnecting it to test again.
