Here are the reasons for different tire pressure readings: 1. Friction coefficient: Each tire experiences slightly different driving conditions, especially in summer when the side exposed to sunlight has a higher temperature, resulting in slightly higher tire pressure. Additionally, ground friction coefficients and minor variations during tire inflation can lead to different tire pressures, which is common as long as the difference is not significant. 2. Types of tire pressure monitoring: Tire pressure monitoring systems are divided into direct and indirect types. Direct tire pressure monitoring systems have pressure sensors and transmitters installed on each wheel, alerting the driver when the tire pressure drops below 25% of the cold tire pressure. Indirect tire pressure warning systems rely on calculating the tire rolling radius to monitor pressure.

What Causes the Abnormal Noise When Reversing?

When reversing, a clicking sound from the chassis may be caused by the brake caliper hitting the caliper bracket during braking. Under gravity, the brake caliper moves downward, and it is floatingly connected to the bracket. When driving forward and braking, there is no "play gap" at the lower connection point with the brake bracket, so no sound is produced. However, when reversing and braking, the brake caliper lifts and impacts the upper bracket, creating an abnormal noise. Below is relevant information about brakes: 1. Introduction: A brake is a device that functions to decelerate, stop, or maintain the stopped state of moving parts (or moving machinery). It is a mechanical component that stops or slows down moving parts in machinery, commonly known as a brake. 2. Composition: Brakes mainly consist of a bracket, braking components, and a control device. Some brakes are also equipped with automatic adjustment devices for the gap between braking components. To reduce braking torque and structural size, brakes are usually installed on the high-speed shaft of the equipment. However, for large equipment with higher safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft near the working part of the equipment.

What to Do If You Accidentally Run a Red Light While Turning Left?

If you run a red light and are caught on camera, you need to go to the local traffic management office or handle the violation on the Traffic Management 12123 app (V2.8.1B437 for iOS 15 and above or V2.8.1B274 for Android 12 and above). According to Article 2, Section 1, Clause 2 of the "Scoring Standards for Road Traffic Safety Violations," driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. However, penalties vary by region. If you stop after crossing the stop line during a red light, some areas may not penalize you. In stricter regions, crossing the stop line during a red light may be considered "over-the-line parking," resulting in a fine of 100 yuan and a deduction of 2 points. Running a red light refers to the act of a motor vehicle violating the prohibition of passage during the red light phase at a signal-controlled intersection or road section, crossing the stop line and continuing to drive. According to Article 26 of the "Road Traffic Safety Law": Traffic signal lights consist of red, green, and yellow lights. A red light prohibits passage, a green light permits passage, and a yellow light serves as a warning. Article 44 states: Motor vehicles passing through intersections must comply with traffic signal lights, traffic signs, traffic markings, or the direction of traffic police. Methods for Traffic Violation Queries: Traffic violation queries refer to checking motor vehicle violations of traffic management through online platforms or query terminals. Methods include website queries, phone queries, mobile app queries, and in-person queries at traffic management offices. Website Query: You can search for "vehicle violation query" and enter your vehicle information to check. Phone Query: Call local 114 (area code + 114) or 12580 to confirm traffic violations. Violations can only be handled at the location where they occurred or where the vehicle's license plate was issued. For on-the-spot violations, such as those caught by traffic police, they must be handled at the violation location. Mobile App Query: For example, on the Traffic Management 12123 app (iOS 15 and above), log in and select "violation query" on the homepage to view and clear unresolved violations. Traffic Management Office Query: Vehicle owners can bring their ID cards to the office or enter their ID number on self-service machines to check violation information and handle it on-site. Important Notes: First, check the arrow light, then the circular light. Currently, there are two types of traffic lights: arrow traffic lights and circular traffic lights. When arrow lights are present, check them first before looking at the circular light to avoid running a red light.

Why is there a noise when braking the car?

It may be related to brake pad wear. Brake pads are consumable items, so they will gradually wear thin during vehicle use. When the friction layer is nearly depleted, there is a warning device at the edge of the brake pad, known as the brake pad wear indicator. At this point, the wear indicator will rub against the brake disc, producing a sharp metal friction sound as a warning to remind the driver to replace the brake pads. The maintenance of the braking system is as follows: 1. Replace brake pads: The braking performance of a vehicle is ultimately determined by the brake pads, so maintaining the good condition of the brake pads is the most direct method of brake system maintenance. Brake pads and brake discs (or drums) have a service life and must be replaced when they wear down to a certain extent. 2. Regularly replace brake fluid: Brake fluid is another critical component of the braking system, second only to the brake pads. The key to brake fluid maintenance is ensuring it does not deteriorate, particularly by preventing moisture ingress. Brake fluid should be replaced every 50,000 kilometers, or more frequently if driving in humid conditions for extended periods. 3. Brake adjustment: If the car noticeably pulls to the left or right when braking, this is due to uneven braking between the front wheels, which can easily lead to accidents, especially at high speeds. Immediate brake adjustment at a repair shop is necessary. 4. New car brake break-in: New cars have a break-in period during initial use, and part of this involves the brake system. The first 1,000 kilometers are crucial for the break-in of a new car, and the brake system also needs this period. It is best to avoid emergency braking during this time.
