Reasons for abnormal noises from newly replaced brake pads: 1. The contact surfaces do not match. When installing new brake pads, the old brake disc was not polished, resulting in improper installation; 2. The brake system itself has defects, causing the brake pads to only partially contact the brake disc. This increases the pressure per unit area during braking, leading to abnormal noises; 3. The replaced brake pads are of poor quality, with overly hard materials containing many metal impurities. After replacing the brake pads, be sure to press the brake pedal several times to eliminate the gap between the brake pads and the brake disc, avoiding accidents caused by the first brake pedal press being ineffective.

Why is there a strong transmission jerking sensation?

Transmission jerking is a relatively common phenomenon. Here are the reasons that may cause jerking: 1. Transmission wear: Severe wear of internal friction plates leads to uneven surfaces, causing contact jerking. 2. Valve body wear: Severe wear of internal plungers in the valve body results in poor plunger movement. 3. Torque converter failure: The torque converter assembly undergoes processes such as cutting, inspection, cleaning, part replacement, welding, high-pressure leak testing, and balancing for remanufacturing to restore its working performance.

How to Use the Vehicle Anti-Skid Button?

The vehicle anti-skid system is usually in an activated state. When the vehicle is at risk of skidding, the system will promptly intervene to maintain body stability and prevent accidents. Here are some introductions about the operation of the vehicle anti-skid system: 1. When stuck on unpaved roads or off-roading: When trapped in mud, sand, snow, or when off-roading in harsh environments, if the drive wheels slip, the ESP will intervene to control power output, which is not conducive to escaping and reduces the vehicle's passability on rough roads. In such cases, you can manually turn off the ESP to improve the vehicle's passability. 2. When driving on icy or snowy roads: In cold regions, where roads are covered with snow and ice, the adhesion of vehicle tires is greatly reduced. When going uphill or starting, the wheels are prone to slipping. At this time, the ESP will limit the engine's power output, which is not conducive to driving. You can try turning off the ESP before driving. 3. When aggressive driving or drifting is needed: During drifting, the drive wheels are usually in a slipping state. When the ESP is working, it will adjust the engine's power output in time to keep the vehicle stable, making it difficult to perform drifting. Therefore, to achieve better drifting effects and track experience, you can turn off the ESP.

Is It Correct to Turn on Hazard Lights in Rainy Weather?

Turning on hazard lights in rainy weather is not entirely correct. According to Article 81 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," in adverse weather conditions such as rain, fog, or snow, fog lights, low beams, marker lights, and front and rear position lights should be turned on. Hazard lights can only be used together with fog lights when visibility is less than 100 meters. Below are relevant introductions about the use of hazard lights: 1. Vehicle accidents or malfunctions: In such cases, hazard lights should be turned on promptly, and a triangular warning sign should be placed 100-200 meters behind the vehicle to alert surrounding drivers of the issue, prompting them to slow down. 2. Temporary parking: If parking is required on a road where temporary parking is allowed, hazard lights must be turned on. Parking in no-parking zones with hazard lights on constitutes a traffic violation. 3. Towing a malfunctioning vehicle: When towing a malfunctioning vehicle, both the towing vehicle and the malfunctioning vehicle must have their hazard lights turned on.

How to Operate the Air Conditioning in the Tenth-Generation Accord?

After starting the car, press the AC button. Below is an introduction to the car air conditioning system: 1. Introduction: The vehicle air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, designed to regulate the temperature and humidity inside the car, providing a comfortable environment for passengers. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser and liquefies, turning into a liquid. When the liquid refrigerant flows through the throttle device, its temperature and pressure decrease, and it enters the evaporator.

Why wasn't I caught speeding when driving at 91 in an 80 km/h zone?

When entering the area, the speed exceeded the limit, but the average speed measured upon exiting the area did not exceed the standard, meaning it was not considered a violation. Below is relevant information about speeding: 1. Definition of speeding: Speeding refers to a driver operating a vehicle at a speed exceeding the legal or regulatory limits. 2. Explanation of illegal speeding: Illegal speeding by motor vehicles typically includes speeding on highways and on roads outside of highways. From the perspective of safe driving behavior, exceeding the legally set maximum speed or the speed limit indicated by signs, or failing to reduce speed as required by law, all constitute illegal speeding. Penalties are imposed according to Article 86 of the "Road Traffic Safety Law of the People's Republic of China" regulations.

Is it necessary to use semi-slick tires for motorcycles?

It is necessary to use semi-slick tires for motorcycles. The following are the specific reasons and functions: Main reasons are as follows: Low cost: Because the cost of full-slick tires is too expensive, semi-slick tires are more cost-effective. Functions: When manufacturing tires, manufacturers add chemical materials such as Kevlar fibers, which enhances the hardness of the tire sidewalls while reducing weight. Semi-slick tires operate at much lower temperatures than full-slick tires but still retain some heat-melting characteristics. Additionally, through the design of tread patterns and drainage grooves, they can achieve grip close to that of full-slick tires, while also offering excellent drainage performance and very high cost-effectiveness.
