Reasons for squealing sounds when braking: 1. Worn brake pads are one of the causes of friction noise during braking. If the brake pads have been used for a long time, the backing plate gradually loses its material, causing metal-to-metal contact and producing harsh noises; 2. Friction noise caused by damaged brake shims. Worn shims come into contact with the braking system, and when metal meets metal, it generates sharp sounds from the braking system. Car brake pads, also known as brake linings, refer to the friction materials fixed on the rotating brake drum or brake disc of the wheel. The friction linings and blocks bear external pressure to create friction, thereby achieving the purpose of vehicle deceleration.

How to Fix Lexus Idle Stop Malfunction?

To resolve a Lexus idle stop malfunction, promptly visit a 4S shop for circuit repair. Below is relevant information about the idle start-stop system: 1. Introduction: The full English name of the idle start-stop system is Idle-Stop-Start-System. Its working principle is that when encountering a red light or traffic jam with vehicle speed below 3km/h, the engine will automatically shut off. When the driver presses the clutch, accelerator pedal, or releases the brake, the starter will quickly restart the engine. 2. Installation: This system is simple and convenient to install, requiring no modification to the car's original circuits. Simply locate the relevant sensor signal lines in the car's electrical system and connect them according to the circuit installation diagram in the manual for immediate use.

What is the normal freezing point of antifreeze?

Antifreeze normally has freezing points of -15°C, -25°C, -30°C, and -40°C. How to choose antifreeze: The basic indicators of antifreeze are the freezing point and boiling point. In the market, antifreeze comes in several specifications with freezing points of -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas. If mixed, multiple additives may react chemically, rendering them ineffective. How to check if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it may indicate low antifreeze levels, though it could also be due to excessively high engine temperature. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Check the water level markings on the antifreeze tank. The antifreeze level should normally be between the maximum and minimum marks. If the antifreeze is below the minimum mark, it indicates a deficiency.

How to reset the tire pressure warning light on the 2021 Mazda 3?

To eliminate the tire pressure warning light on the 2021 Mazda 3, simply perform a tire pressure reset. The method for tire pressure reset is as follows: First, turn on the ignition, then press and hold the tire pressure monitoring reset button. After hearing a "beep" sound, release the button. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the completion of the tire pressure reset. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver to leaks or low pressure to ensure driving safety. There are generally three reasons for abnormal tire pressure warnings: Abnormal tire pressure: The system typically alerts when pressure is below 1.8 bar or above 3.0 bar. In this case, inspect the tires and adjust the pressure accordingly. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the system will continue to display the old data, causing the warning light to stay on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors the tire pressure. If the sensor is damaged due to impact while driving, it can trigger the tire pressure warning light. In such cases, the only solution is to replace the sensor with a new one.

Should Minor Scratches on a New Car Be Polished?

Scratches can indeed be removed through polishing. Polishing involves the high-speed rotation of a polishing wheel, which can grind away the oxidized layer and dirt on the car's paint surface, effectively eliminating minor scratches. However, it's important to note the frequency of polishing. Frequent polishing can, to some extent, damage the car's paint. As the paint is continuously ground down, it becomes thinner, reducing the car's ability to maintain itself. Below is additional information on scratch polishing: 1. If a new car develops scratches, polishing is an option, especially for minor scratches. The paint can still withstand it. However, it's recommended to use wax instead, specifically abrasive wax. The special grinding particles in abrasive wax can also remove scratches, and compared to polishing, waxing is less likely to harm the new car's paint and is a more reassuring option. 2. If the scratches are deep and reach the primer or metal layer, the paint should first be repaired. After the paint has fully hardened, a detailed polishing process can be performed. New car paint is of high quality and less prone to oxidation, so regular maintenance is sufficient, and polishing isn't necessary. For older cars, typically after 3-5 years when the paint begins to age, polishing can help restore the paint's shine.
