The reasons why the brake makes noise when reversing: 1. Normal noise phenomenon; 2. Brake pad wear; 3. There is a certain gap between the brake pad and the rear end of the bracket. The working principle of the brake mainly comes from friction. By using the friction between the brake pads and the brake disc, as well as the friction between the tires and the ground, the kinetic energy of the vehicle is converted into heat energy after friction, thereby stopping the vehicle. Brake inspection steps: 1. Check the brake pads. The effectiveness of the brake largely depends on the condition of the brake pads, so checking whether the wear degree of the brake pads is normal is of great significance to ensure brake performance; 2. Check the brake fluid. Pay attention to the weather characteristics of the location and destination to prevent excessive moisture from entering the brake fluid, which may have adverse effects on the brake.

I've been driving for twenty years, and sometimes when I brake while reversing, it makes a very loud noise, mainly because the brake pads are worn too thin, and the metal parts start to rub. Especially when reversing at low speeds, accumulated dust or rust on the brake discs can suddenly be pressed down, causing a squeaking sound. I remember after changing my car two years ago, several times when reversing in the garage, the brakes would screech loudly as soon as I stepped on them. Upon inspection, I found that the brake pads were nearing the end of their lifespan. Driving habits also play a big role—for example, braking unevenly while reversing can easily cause uneven stress on the components. I recommend developing a habit of braking gently. If the noise gets loud, go to a repair shop and get it checked—don’t delay until it turns into a more serious brake failure. Regular maintenance can prevent these issues and also save fuel and money—a win-win.

What Causes Abnormal Noises in the Vehicle Chassis?

Here are the reasons for abnormal noises in the vehicle chassis: 1. Noises during vehicle startup are generally caused by faults in the suspension system, possibly due to loose or damaged engine mounts. 2. Noises during vehicle steering may be caused by faults in the steering system or suspension system. As the vehicle tilts during steering, the suspension system deforms and participates in the movement. 3. Noises during driving on good road conditions may be caused by faults in the braking system components, such as loose or worn parts, out-of-round brake drums, or uneven brake discs. 4. It could also be due to issues with the bearings that connect moving and stationary parts. If it's a bearing issue, the driver can identify it by applying slight braking. If the noise remains unchanged when braking at a constant speed, it indicates a bearing problem. 5. Noises during driving on poor road conditions are mostly caused by issues in the suspension system or possibly loose braking system components. 6. Noises during acceleration, deceleration, or stopping are mostly caused by the suspension system or braking system. Friction sounds from the suspension system are common. To reduce these noises, drivers should avoid rough driving, minimize bumps, slow down on poor road conditions, and avoid driving through water, which can effectively reduce abnormal noises in the vehicle chassis.

Why Does the Shock Absorber Make Metal Noise When Cold but Not When Hot?

This situation usually occurs due to oil leakage from the shock absorber or damage to the shock absorber itself. The owner can inspect it themselves or visit a professional 4S shop or repair shop for inspection and maintenance, which may involve replacing the shock absorber. Below is some relevant information: 1. Definition of Shock Absorber: The car shock absorber (including the shock spring) is the most important component in the vehicle's vibration filtering system. 2. Function of Shock Absorber: It absorbs vibrations and impacts caused by uneven road surfaces during driving, thereby providing a comfortable ride for passengers. 3. Hazards of Damaged Shock Absorber: Once the shock absorber is damaged, the vehicle may experience excessive bumpiness and instability while driving, which can severely impact driving safety in serious cases. 4. Common Damages to Shock Absorbers: (1) Abnormal Noise: If the shock absorber makes unusual noises when driving on bumpy roads, it is highly likely that the shock absorber is damaged. (2) Oil Leakage: By using a flashlight to inspect the shock absorber through the wheel arch, if oil leakage is observed on the exterior of the shock absorber, it indicates that the shock absorber is already damaged. (3) Loose Chassis: When driving on bumpy roads, if the vehicle's body exhibits excessive bumpiness and instability, it is often a sign that the shock absorber is malfunctioning.

Which Gear is Most Effort-Saving for Mountain Bikes When Climbing Uphill?

When climbing uphill on a mountain bike, using gears 1-7 is the most effort-saving. Here are the specific details about mountain bikes: 1. Creation Background: Mountain bikes are specifically designed for off-road travel (hills, trails, wilderness, and gravel roads, etc.) and were first introduced in 1977 in San Francisco on the West Coast of the United States. 2. Development Prospects: The focus of the global bicycle industry is shifting from traditional commuting vehicles to sports, mountain, and leisure types. In developed countries like the U.S., Europe, and Japan, bicycles are a common product for sports, fitness, leisure, and entertainment. 3. Main Features: The primary characteristics of mountain bikes include wide tires and straight handlebars. The wide and multi-toothed tires provide traction, and shock absorbers help absorb impacts. 4. Gear Performance: Mountain bikes typically come with 11-speed, 18-speed, 20-speed, 21-speed, 24-speed, 27-speed, and 30-speed options. Proper use of the gear system allows riders to handle complex terrains and weather conditions such as flat roads, uphill and downhill slopes, dirt roads, and headwinds, making them faster and more effort-saving than regular bicycles.

Must the driver's license expire before it can be renewed?

A driver's license does not have to expire before it can be renewed. Motor vehicle drivers should apply for renewal at the vehicle management office where the driver's license was issued within 90 days before the expiration of the license's validity period. When applying, the "Motor Vehicle Driver's License Application Form" should be filled out. Other methods for renewing a driver's license are as follows: Renewal via the "Traffic Management 12123" APP. Download the "Traffic Management 12123" APP, then select Service Center -- Expiration Renewal Service -- Fill in the information. The new license is generally delivered by mail. Go to the "Police-Medical-Post" service point at the postal business hall to process the renewal. The entire process, from registration and physical examination to the production of the new license, takes only half an hour. Currently, only a few cities have opened this service, such as Hangzhou. Renewal materials: Bring two copies of ID card, two 1-inch recent color photos without hats, original ID card, original driver's license, and a physical examination certificate from a county-level or above hospital (free physical examination is also available at the vehicle management office).

What are the distances for viewing the rear car in the right side mirror?

When the rear car occupies 1/3 of the area in the right side mirror, the distance is approximately 15 meters. When the rear car occupies half of the right side mirror, the distance is about 10 meters. When the rear car occupies half of the right side mirror, this indicates the rear car is very close, and it is not advisable to perform turning maneuvers. Function of rearview mirrors: The rearview mirror is one of the important safety components of a motor vehicle's body, used to observe the road conditions behind the car during reversing and to monitor the surroundings while driving. For the convenience of the driver and to prevent traffic safety accidents, ensuring personal safety, all countries mandate that vehicles must be equipped with rearview mirrors, and all mirrors must be adjustable in direction. Classification of rearview mirrors: There are mainly two types of rearview mirrors in vehicles: one is a flat mirror, which, as the name suggests, has a flat surface, similar to typical household mirrors, providing an image the same size as seen by the naked eye. This type of flat mirror is commonly used as the interior rearview mirror. The other type is a convex mirror, which has a spherical surface with varying radii of curvature. Its image is smaller than what the naked eye sees but offers a wider field of view, functioning like a camera's "wide-angle lens." This type of convex mirror is commonly used as the exterior rearview mirror and the lower rearview mirror.
