Brake discs generally need to be replaced when the vehicle has traveled 80,000 to 100,000 kilometers. Below are the classifications of brake discs and the criteria for determining when replacement is necessary: Classifications of brake discs: Brake discs can be divided into solid brake discs and ventilated discs based on their structural form. Based on material differences, they can be categorized into carbon fiber ceramic brake discs and metal brake discs. Criteria for determining when brake discs need replacement: Observe the brake disc warning light. Normally, the brake disc indicator light is off. When the brake disc malfunctions or is excessively worn, the light will turn on and will turn off after repairs; Check the thickness of the brake disc. Most brake disc products have wear indicators. When the total wear depth on both sides of the brake disc reaches 3mm, it is recommended to replace the brake disc promptly; Listen for sounds. If there are abnormal noises when lightly applying the brakes, the brake pads must be replaced immediately.

Where is the cabin air filter located in the BYD S6?

The cabin air filter in the BYD S6 is located beneath or inside the glove compartment on the passenger side. Failure to properly maintain the cabin air filter can lead to accumulation of dust and dirt on the filter screen, radiator, evaporator, and fin surfaces, resulting in airflow blockage. This may cause reduced cooling/heating efficiency, increased power consumption, noise issues, and shortened service life of the air conditioning system. Functions of the cabin air filter: 1. Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc. in the air; 2. Ensures clean cabin air free from bacterial growth, creating a healthy environment; 3. Effectively filters out solid impurities like pollen and abrasive particles, preventing allergic reactions that could compromise driving safety.

What is the problem when a car revs by itself without stepping on the accelerator?

When a car revs by itself without stepping on the accelerator, it is mostly due to an issue with the idle motor. It is recommended to check the idle motor and clean the throttle body at the same time. If the car revs on its own without pressing the accelerator, the cause should be analyzed based on different situations. For electronic throttle systems, focus on checking the throttle and accelerator pedal. For cable-operated throttles, inspect the throttle cable and idle motor. Throttle issue: The throttle cable may not be returning properly, possibly due to insufficient lubrication. Solution: Remove the cable, pour lubricating oil from the upper end of the cable, and allow the oil to slowly penetrate into the cable tube. Idle motor problem. For example, the idle motor may be stuck or have lost its memory. Solution: Clean or replace it and then recalibrate. This requires initialization using a diagnostic computer.

What to Do When Taking the Subject 2 Driving Test on a Rainy Day?

The examiner will also be concerned about driving safety, so prioritize safety over passing the test. 2. Maintain a safe distance. Keep a proper distance from the vehicle ahead during the test and avoid sudden braking. Instead, use gentle or intermittent braking to prevent test failure due to harsh stops. 3. Remember to turn on the windshield wipers. During practice, you might not use them often as the weather is usually good, but don’t forget to activate them on rainy test days. The wiper switch is located on the lower right side of the steering wheel, opposite the turn signal switch on the left. Adjust the wiper speed according to the intensity of the rain. 4. Stay calm. If you encounter rain during the Subject 2 test, adjust your mindset and remain composed, avoiding any negative impact from the weather.

What are the causes of high pressure in car air conditioning?

The causes of high pressure in car air conditioning: 1. System blockage, mostly due to expansion valve blockage or malfunction, the solution is to replace the expansion valve; 2. Excessive refrigerant, the exhaust port feels hot to the touch and the suction port feels warm, normally these areas should feel cool, the compressor may occasionally make liquid impact sounds, the solution is to completely evacuate and quantitatively recharge the refrigerant; 3. Poor cooling of the condenser, the temperature of the pipeline from the condenser outlet to the expansion valve inlet feels hot to the touch, normally this section should feel warm, the solution is to clean the condenser and radiator grille of dirt, replace if necessary; 4. Expansion valve failure, the low-pressure pipe will have a large number of dew drops or frost, the solution is to check if the expansion valve is installed correctly, if correct, replace the expansion valve; 5. Other faults, such as cooling fan failure, engine overheating, excessive or insufficient refrigeration oil.
