Why Do Car Brakes Make Noise?

Car brakes make noise due to the following reasons: 1. Presence of metal particles in the brake pads; 2. Excessive wear of the brake pads; 3. Excessive wear of the brake discs; 4. Installation issues. Solutions for noisy car brakes include: 1. Replacing with better-quality brake pads; 2. Reinstalling the brake pads. Wear on the brake discs can create deep grooves around the disc, and friction between the brake pads and the edges of these grooves can cause noise. If the grooves are not too deep, the issue can be resolved by grinding the edges of the brake pads to avoid contact with the groove edges. If the grooves are already very deep, it is recommended to replace the brake discs. Generally, it is advised to replace the brake discs once for every two brake pad replacements.

What to Do When the Car Lock Freezes and Won't Lock?

Solutions for a frozen car lock that won't lock: 1. Use warm water to melt the ice on the door. It's important to use warm water, not hot water, as hot water can damage the car's paint. 2. Use a hairdryer to blow hot air directly at the lock cylinder. Once the lock cylinder is heated, it should open. 3. Heat the key's teeth with a lighter or match, then insert it into the lock cylinder. Repeat this process several times to melt the frozen lock. Be careful not to overheat the key, especially if it contains an anti-theft chip. 4. If the door is frozen while you're inside the car, turn on the car's air conditioning and drive to a warm indoor location to thaw the lock.

When visibility is less than 200 meters, what should the speed and distance between vehicles be maintained?

According to Article of the "Road Traffic Safety Law," when visibility is less than 200 meters, maintain a distance of more than 100 meters from the vehicle ahead in the same lane, and the speed should not exceed 60 kilometers per hour. Turn on the fog lights, low beams, clearance lights, and front and rear position lights. When motor vehicles are driving on highways and encounter low visibility weather conditions such as fog, rain, snow, dust, or hail, the highway management department should issue speed limits and distance-keeping reminders via display screens. A safe distance refers to the necessary gap that a following vehicle must maintain with the vehicle ahead to avoid accidental collisions. When driving on highways and encountering low visibility weather conditions such as fog, rain, snow, dust, or hail, the following regulations must be observed: When visibility is less than 500 meters but greater than 200 meters, low beams, width indicators, and rear fog lights must be turned on; the speed should not exceed 80 km/h; maintain a driving distance of more than 150 meters; When visibility is less than 100 meters, turn on fog lights, low beams, clearance lights, front and rear position lights, and hazard warning flashers; the speed should not exceed 40 kilometers per hour, and maintain a distance of more than 50 meters from the vehicle ahead in the same lane; When visibility is less than 50 meters, turn on fog lights, low beams, clearance lights, front and rear position lights, and hazard warning flashers; the speed should not exceed 20 kilometers per hour, and exit the highway from the nearest exit as soon as possible. Precautions for driving in foggy conditions: Make good use of lights. When driving in fog, visibility is low, so fog lights and clearance lights must be turned on, and high beams are prohibited. High beams shine upward, and the light is diffusely reflected by the fog, turning into a white light in front of the vehicle, which is not conducive to driving. Fog lights have high light penetration, and turning them on allows other vehicles to clearly identify your position. Maintain a safe distance from the vehicle ahead, do not follow too closely, and avoid overtaking casually. This prevents insufficient reaction time in case of an accident, which could lead to a rear-end collision; Frequently honk the horn to indicate your position.

What are the hazards of high tire pressure?

The hazards of high tire pressure are: 1. It reduces the friction and adhesion of the tire, affecting braking performance and shortening tire lifespan; 2. It decreases the tire's resistance to punctures, increasing the risk of a blowout; 3. It accelerates wear on the central tread pattern, reducing tire lifespan, increasing vehicle vibration, and indirectly affecting the lifespan of other components; 4. It causes excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving, which lowers puncture resistance; 5. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, leading to internal cracks and blowouts due to impact.

What is the normal tire pressure for the Pajero?

The normal tire pressure for the Pajero ranges between 2.3bar and 2.5bar. The recommended tire pressure range can be found on the vehicle's user manual or on the label near the driver's side door (B-pillar). Tire pressure refers to the air pressure inside the tires, and it plays a crucial role in the performance and power of the vehicle, much like blood pressure for a car. The Pajero is an off-road vehicle produced by Mitsubishi Motors Corporation of Japan. It measures 4900mm in length, 1875mm in width, and 1900mm in height, with a wheelbase of 2780mm. It has a top speed of 175km/h and is powered by a 3.0L 174-horsepower V6 engine, paired with a 5-speed automatic transmission.

What is the emission standard for 2011 sedans?

2011 sedans belong to the China IV emission standard, which was implemented starting in 2011. This means all sedans produced in 2011 comply with the China IV standard. Automobile emissions refer to harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot) discharged from exhaust. These are all harmful byproducts generated during engine combustion. To control these emissions and encourage manufacturers to improve their products, both Europe and the United States have established relevant automobile emission standards. China's emission standards are based on European standards. Currently, all domestically produced new vehicles indicate the European standard their engine emissions meet. China's Light-Duty Vehicle China III and China IV emission standards have identical pollutant emission limits to Euro 3 and Euro 4 standards, but with some improvements in testing methods and significant differences in regulatory format. Considering that vehicles have been in use for some time, the emission limits for in-use China IV standard vehicles are slightly more lenient compared to new vehicles. However, they are still 34% stricter than China III standards. For China IV vehicles, the initial inspection interval is every two years. During annual inspections, vehicle emissions must meet the published standard limits; otherwise, maintenance is required before passing the inspection. Additionally, the current local emission standards for oil storage depots, tanker trucks, and gas stations regarding vapor recovery have been tightened. Compared to the original standards, the emission limits for oil storage depots' vapor treatment devices are 25% stricter. Gas stations are now required to install online monitoring and vapor emission treatment systems. These measures can improve vapor recovery efficiency by 5% to 10%, and the online monitoring system can track the working status of vapor recovery equipment in real time.
