What Causes Brake Pad Noise in Cars?

Automobile brake pad noise can be attributed to the following reasons: 1. New car brake noise: Since the brake pads and discs of a new car are in a brand-new state and haven't been worn in, noise may occur. 2. Foreign objects or water film between brake discs and pads: On rainy days, brake pads tend to be damp, making them prone to noise at low speeds. After the vehicle is parked, a slight condensation forms on the surface, causing noise during the first drive the next day. Additionally, foreign objects like sand, small stones, or other particles between the brake pads and discs can also lead to noise. 3. Noise when braking in reverse: The noise occurs during reverse braking due to changes in the friction pattern of the brake pads. 4. Rust on brake discs: The vehicle's brake discs and pads may rust due to driving through water or prolonged parking, especially after long-term use of the handbrake, causing the brake discs and pads to stick together and produce noise during the initial drive. 5. Brake pad wear limit warning sound: When brake pads wear down to their limit, the warning tab will rub against the brake disc, producing a sharp metallic friction sound. It is essential to promptly visit a service station for brake pad inspection or replacement to prevent damage to the brake disc and brake failure.

How Many Years Can a Car Generally Last?

Under normal driving conditions, a car can last for 20 years. The specific lifespan of a car is influenced by many practical factors. The scrappage policy for cars has eliminated the 15-year mandatory scrappage period, replacing it with a guided scrappage at 600,000 kilometers. If a car is driven 20,000 kilometers annually, it can last for 30 years; if driven 30,000 kilometers annually, it can last for 20 years. During the use of a car, its components will gradually age with the frequency of use, and its performance will also decline over time. Starting from the 15th year of use, the car must undergo two annual inspections per year; from the 21st year, the number of annual inspections even increases to four. If the car fails the annual inspection due to component aging and performance degradation, it will also need to be scrapped. For licensed vehicles that do not meet the standards, they will be guided to be scrapped or forcibly scrapped. The specific mandatory scrappage regulations are as follows: vehicles that still do not meet the national standards for in-use vehicles regarding safety technical requirements after repair and adjustment; vehicles that still do not meet the national standards for in-use vehicles regarding atmospheric pollutant emissions or noise after repair, adjustment, or the use of control technology; vehicles that fail to obtain the motor vehicle inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection period; vehicles that have reached a certain age and mileage.

What Causes Shock Absorber Oil Leakage?

Shock absorber oil leakage can be caused by the following reasons: 1. Poor internal cleanliness of the shock absorber, with welding slag, iron filings, and other debris causing oil seal wear. 2. Harsh working conditions of the shock absorber, allowing external debris like mud and sand to enter the oil seal. 3. Aging of the sealing interface of the shock absorber oil seal, resulting in loss of sealing function. 4. Failure to properly cover the shock absorber during undercoating application, leading to coating adhering to the shock absorber piston rod. 5. The extension of the control piston rod at one end of the metal tube, where poor sealing occurs. Solutions for shock absorber oil leakage are as follows: 1. Oil traces on the shock absorber body do not necessarily indicate leakage. Determining whether a shock absorber is leaking or failing depends on factors such as the type of shock absorber, leakage level, and oil trace location. For shock absorbers with only minor seepage, replacement may not be necessary. Additionally, some oil seepage is normal during shock absorber operation. 2. However, for strut-type shock absorbers like front shock absorbers, if the oil film is between the oil seal cover and spring seat, replacement is not required. But if oil leaks below the spring seat or permeates below the spring bracket, or if oil droplets appear, the shock absorber should be replaced.

How to Check the Odometer on a BMW 5 Series?

BMW 5 Series allows you to observe remaining fuel range, mileage, display time, etc., through the toggle buttons under the onboard computer. Below are detailed introductions about the BMW 5 Series: 1. Specific steps to check the odometer on BMW 5 Series: There is a button marked with 'M' on the turn signal stalk. Press this button, and the small screen on the dashboard will display garbled characters. Then, press the circular button on the head of the stalk and rotate the ring on the stalk to switch the displayed information. Finally, press the circular button to confirm. 2. Changes in the exterior of BMW 5 Series: The 2020 BMW 5 Series new car, based on the Premium model, adds a panoramic sunroof, Bowers & Wilkins sound system, and comfort seats, with the option of run-flat tires. 3. Changes in the configuration of BMW 5 Series: The new BMW 5 Series has adjusted its configurations, with overall additions and reductions. The entire lineup has removed four colors, including Brazilian Brown, Platinum Silver, Burgundy Red, and Hukaro Beige, as well as the Innovation Package, Hi-Fi Sound System, and electric sunshades for the rear and side windows. It is equipped with a 10.25-inch central control screen, 12.3-inch LCD instrument panel, Apple CarPlay, ambient lighting, and aviation headrests.

What Causes the Fuel Injector in a Buick Regal to Stop Spraying Fuel?

There are several reasons why a fuel injector may stop spraying fuel, including insufficient fuel, a damaged fuel pump, a faulty high-pressure fuel pump, clogged fuel injectors, or leaks in the fuel line connections, all of which can prevent the injector from functioning properly. Below is a detailed explanation: 1. Definition: A fuel injector is essentially a normally closed valve (meaning the valve remains closed when no control signal is received; conversely, a normally open valve stays open without a control signal). The opening and closing of the valve are controlled by the movement of a needle valve. When the ECU sends a fuel injection command, the voltage signal generates a current through the injector's coil, creating a magnetic field that lifts the needle valve, allowing fuel to spray out through the injector nozzle. The primary advantage of fuel injection is its precise control over fuel delivery, ensuring the engine maintains the correct air-fuel ratio under all conditions. This not only keeps the engine running smoothly but also ensures that emissions comply with environmental regulations. 2. Troubleshooting: A fine needle can be used to unclog the injector, followed by thorough cleaning. If the needle valve's large flat surface does not properly contact the injector body's flat surface, or if the needle valve's cylindrical surface is significantly worn, corrective measures are needed. For poor contact between the needle valve's flat surface and the injector body, chromium oxide can be applied to a flat plate for figure-8 grinding. If the needle valve's cylindrical surface is excessively worn, the needle valve assembly should be replaced as a matched pair.

Why is the Buick Regal's Start-Stop Function Not Responding?

Buick Regal's Start-Stop Function Not Responding_58 Auto The reason why the start-stop system of a Buick vehicle is not working may be due to a blockage in the car's oil and gas pipeline system, which causes the start-stop system to malfunction. Below are the relevant details: 1. Introduction to the Automatic Start-Stop System: Its main advantage is fuel efficiency. Whether at a red light or in traffic, the engine automatic start-stop technology can automatically shut off the engine when the vehicle is stationary to save fuel. 2. Development History: This technology first appeared as early as the mid-1970s. At that time, Toyota conducted practical tests on this technology in the Crown sedan. As long as the vehicle came to a complete stop for 1.5 seconds, the engine would automatically cut off fuel and shut down, which became the theoretical and design prototype for the future development of automatic start-stop systems.
