The causes of brake friction noise may include excessively hard brake pads, worn brake pads down to the backing plate, excessive wear of brake discs or drums, rusted brake calipers, stiff parking brake cables, slow return of the master cylinder, etc. It is necessary to visit a 4S shop for inspection and repair. Below is an introduction to brake pedal operation: 1. Introduction to brake pedal operation: Automobile brake pedal operation can be categorized into gradual braking (i.e., anticipatory braking), emergency braking, combined braking, and intermittent braking. Generally, during gradual braking and emergency braking, the clutch pedal should be fully depressed before the wheels lock up and the vehicle comes to a stop, to prevent the engine from stalling and facilitate speed readjustment. 2. Proper timing and force application in braking: Under normal circumstances, avoid stomping the brake pedal all at once. First, press the brake pedal, adjusting the foot pressure (i.e., increasing the force) as needed—apply quick and firm pressure when the speed is high, and light and steady pressure when the speed is low. Then, adjust the pressure increase or decrease based on various conditions.

What does traffic violation code 1356 mean?

Violation code 1356 means: Failing to slow down when passing through a pedestrian crossing. Article 47 of the Road Traffic Safety Law of the People's Republic of China states: When motor vehicles pass through pedestrian crossings, they shall slow down; when encountering pedestrians crossing the road, they shall stop to yield. When motor vehicles pass through roads without traffic signals and encounter pedestrians crossing the road, they shall yield. Article 3 of the Scoring Standards for Road Traffic Safety Violations: If a motor vehicle driver commits any of the following violations, 3 points will be deducted: Driving a motor vehicle through a pedestrian crossing without slowing down, stopping, or yielding to pedestrians as required. 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 scoring classification code, the third and fourth digits are sequential codes, and the fifth digit indicates the specific item number. First digit: Behavior classification code, indicating the category of the violation under the Road Traffic Law. Second digit: Scoring classification code, indicating the points deducted for the traffic violation. Third and fourth digits: Sequential code, indicating the order of the violation within the same behavior category. For example: 13035—"1" indicates a motor vehicle violation, the second digit "3" indicates 3 points will be deducted, and "035" indicates the fifth item of the third violation under the 3-point deduction category. 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 provincial, autonomous region, or municipal implementation rules, e.g., 7008. Codes starting with 8 indicate local regulations of cities (regions, autonomous prefectures, or leagues), e.g., 8606. There are four common methods to check motor vehicle violations: Visit the office halls of traffic police departments in various districts and counties to query through touch terminals. Log in to the public service websites of local public security traffic management bureaus, find the vehicle violation query section, enter the license plate number and engine number, and click to query. Call the hotline (area code + 114) to inquire. Use the Traffic Management 12123 app (V2.8.1B437 for iOS 15+ or V2.8.1B274 for Android 12+) to query.

Why is there a buzzing sound from the electric motor in the right rear wheel after turning off the engine?

This situation is normal. It is the sound of the exhaust pipe contracting, and the noise will disappear after a few minutes. Models equipped with electronic parking brakes may also experience this phenomenon, which is the sound of the electronic parking brake motor and is also normal. Here is some extended information: 1. Working principle: The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both achieving parking braking through the friction generated between the brake disc and brake pads. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button. 2. Thermal expansion and contraction of the car exhaust pipe: When the car is running, it burns gasoline, and through complex chemical reactions, part of the energy is converted into heat energy, which is discharged through the exhaust system. The muffler is basically at the end of this system and its function is to reduce the noise of the exhaust. The muffler has to withstand the impact of hot airflow when working, so it naturally heats up. After turning off the engine, due to thermal expansion and contraction, it will make a whirring sound for a while, sometimes quite loud, which is all normal.

Can the Rearview Mirror Glass Be Replaced Separately?

The rearview mirror glass can be replaced separately, and the new glass can be installed directly. Here is some relevant information about rearview mirrors: 1. Classification of Rearview Mirrors: Rearview mirrors are categorized by their installation positions into exterior rearview mirrors, lower rearview mirrors, and interior rearview mirrors. By purpose, the exterior rearview mirrors reflect the rear and side of the car, the lower rearview mirrors reflect the front and lower part of the car, and the interior rearview mirrors reflect the rear of the car and the interior situation. Different purposes lead to different mirror structures. 2. Adjustment Methods for Rearview Mirrors: Adjust the left and right positions so that the left edge of the mirror just cuts off your right ear in the reflection, which means that under normal driving conditions, you cannot see yourself in the central rearview mirror. For the up and down positions, place the distant horizon in the center of the mirror. The key to adjusting the central rearview mirror is to place it horizontally in the middle and position your ear on the left. Place the distant horizon horizontally along the centerline of the central rearview mirror, then move it left or right so that the image of your right ear is just at the left edge of the mirror.

That is to say, the Subject 1 exam on the same day will be conducted in different sessions according to different exam times, with each session lasting 45 minutes. The number of sessions each day is set by the vehicle management office based on its own scale. Generally, the first session of Subject 1 is at 9:00; the second session of Subject 1 is at 10:00; the third session of Subject 1 is at 13:00; the fourth session of Subject 1 is at 14:00; and the fifth session of Subject 1 is at 15:00. In some cities with a large population, it is recommended to book three exam sessions simultaneously when making an appointment. Because in places with many people, there are many people booking exams every day, and the exam slots are relatively tight. Therefore, for Subject 1, not only should you book three full sessions, but you should also choose sessions that are ranked higher. Even if one appointment is unsuccessful, you still have two other sessions booked, which can increase the success rate of the appointment. Subject 1 is the exam on road traffic safety laws, regulations, and related knowledge. There are 100 questions in total, all randomly selected and combined from a pool of more than 1,700 questions. The question types for Subject 1 are true/false and single-choice questions, with 30 true/false questions and 70 single-choice questions. The main content assessed includes the theoretical basis of driving, road safety laws and regulations, traffic signals, traffic rules, and other basic knowledge, as well as local regulations. The full score for the Subject 1 exam is 100, with a passing score of 90 or above. During the exam, if you accumulate more than 10 wrong answers, the exam will automatically end. If you do not exceed 10 wrong answers, the exam score will be announced immediately after the exam. In addition, if you fail the Subject 1 exam, you will have one chance to retake the exam on the spot. If you fail both exams, you will have to reschedule a retake. There is no limit to the number of times you can book the Subject 1 exam.
