What Causes Severe Vibration When Braking a Car?

Severe vibration when braking a car can be caused by: 1. Tire deformation; 2. Improper tire dynamic balance; 3. Vehicle drivetrain malfunction; 4. Worn or loose ball joints or detached rubber bushings at connections; 5. Twisted or deformed drive shaft; 6. Uneven brake discs; 7. Overly loose or tight power steering belt. The brake is a mechanical braking device that slows down the vehicle, also known as a decelerator. The car's brake pedal is located below the steering wheel. Pressing the brake pedal activates the brake linkage, transmitting pressure to the brake shoes on the brake drum, which then clamp the brake rotor to decelerate or stop the vehicle. Brake maintenance tasks include: 1. High-temperature protection for brake pads; 2. Lubrication maintenance for brake calipers; 3. Cleaning of brake discs; 4. Replacement of brake fluid; 5. Rust prevention and lubrication for wheel bolts, brake discs, and contact surfaces with rims.

Last time I braked, the car shook violently. After checking at the repair shop, it was found that the brake disc was warped. The mechanic said this is usually caused by the brake disc overheating and then encountering cold water, such as washing the car immediately after driving on mountain roads or braking during rainy weather. When the brake disc is uneven, you can feel the steering wheel shaking when you apply the brakes. It could also be due to uneven wear of the brake pads, causing uneven force on the brake disc. Another possibility is an issue with wheel balance—if the balancing weights on the wheel hub fall off, it can cause similar symptoms. I later replaced the brake disc, and the problem was resolved. It's recommended to avoid prolonged continuous braking, reduce the number of sudden brakes, and regularly check the thickness of the brake pads and the smoothness of the brake disc surface.

What is the compensation standard for a total loss of a new car?

The purchase price of a new car includes the vehicle purchase tax, so the purchase price of the new car at the time of the accident = the purchase price of a similar model in the market at the time of the accident × (1 + vehicle purchase tax). Below is the relevant introduction: Residual value: Refers to completely unusable scrap parts, which are deducted based on the price they can be sold for. The ownership of the residual value is determined through negotiation between the two parties involved in the insurance. If it is assigned to the policyholder for disposal, the residual value is subtracted from the assessed loss; if it is reclaimed by the insurance company, the residual value is not subtracted. Depreciation rate: Current policy terms specify a monthly depreciation rate, clearly stating that depreciation is calculated based on the monthly rate, with a note that the maximum depreciation amount shall not exceed 80% of the new car's purchase price. If there are significant differences in specific cases, the policyholder can negotiate with the insurance company.

What is the sign for a dangerous mountain road section?

The dangerous mountain road sign is a traffic sign placed at an appropriate location before sections of mountainous terrain that are hazardous (such as roads with steep cliffs or dangerous drop-offs on the outer side). Below is relevant information: Sign placement: It is positioned at an appropriate distance before sections where the road's friction coefficient cannot meet the required emergency braking distance for the corresponding driving speed. Drivers must slow down when approaching these sections. This sign is placed at an appropriate location before hazardous mountainous terrain (roads with steep cliffs or dangerous drop-offs on the outer side). It is also placed before sections along reservoirs, lakes, rivers, or other embankment roads. Purpose of warning signs: To alert drivers and pedestrians of potential dangers ahead, urging them to proceed with caution. Most warning signs have a yellow background with black borders and black symbols, and their shapes include rectangles, squares, crosses, and equilateral triangles with the apex pointing upward.

Those holding a driver's license for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large trucks must visit the vehicle management office at the place where the license was issued or elsewhere to exchange it for a license permitting the operation of small cars or small automatic transmission vehicles. Individuals aged 70 or above: are prohibited from driving low-speed trucks, three-wheeled vehicles, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, and wheeled self-propelled machinery. Those holding a driver's license for ordinary three-wheeled motorcycles or ordinary two-wheeled motorcycles must visit the vehicle management office at the place where the license was issued or elsewhere to exchange it for a license permitting the operation of light motorcycles.

Is it normal for a new car to leave the factory four months ago?

It is normal for a new car to have been out of the factory for four months. Here is the relevant introduction: Within 3 months: Strictly speaking, a car within 3 months is not considered a stock car, but anything under half a year is generally acceptable. Stock car: There is no clear legal definition, but within the automotive sales industry, the term "stock car" does exist. It typically refers to domestically produced cars that have not been sold for more than 3-5 months after leaving the factory, as well as imported cars that have not been sold for more than 6 months after leaving the factory. Things to note: When picking up the car, pay attention to the odometer reading, which is usually between 20-80 kilometers. As a commodity, cars are large in size, expensive, have high storage costs, and tie up a significant amount of dealer capital. Therefore, dealers generally do not allow inventory cars to remain in stock for an extended period.

Is a Four-Wheel Drive Car Faster or a Two-Wheel Drive Car Accelerates Faster?

If the horsepower and transmission are the same, generally a four-wheel drive car will start faster than a two-wheel drive car because the wheel traction is greater. Meaning of Two-Wheel Drive: Two-wheel drive means that two wheels are driven, usually either front-wheel drive or rear-wheel drive, while four-wheel drive means all four wheels can be driven, meaning both the front and rear wheels can be driven simultaneously. Four-Wheel Drive: Four-wheel drive has advantages when driving on poor roads, such as if the front wheels slip, the rear wheels can be used for driving, making it suitable for off-roading, but it consumes more fuel. Two-wheel drive, on the other hand, is more suitable for urban commuting, with relatively lower fuel consumption compared to four-wheel drive, but its off-road performance is inferior to four-wheel drive.

Where is the battery located on a underbone motorcycle?

The battery of an underbone motorcycle is mostly located inside the right side cover, above the kick starter lever. Introduction to automotive batteries: Automotive batteries, also known as storage batteries, are primarily made of lead and its oxides, with sulfuric acid solution as the electrolyte. Their working principle involves converting chemical energy into electrical energy. Classification of automotive batteries: They are divided into three types: conventional batteries, dry-charged batteries, and maintenance-free batteries. Conventional batteries have plates composed of lead and lead oxides, with an electrolyte of sulfuric acid solution. Dry-charged batteries are characterized by their negative plates having high electrical storage capacity, allowing them to retain stored electricity for up to two years in a completely dry state. When needed, simply add the electrolyte and wait 20-30 minutes before use. Maintenance-free batteries, due to their structural advantages, have minimal electrolyte consumption and generally do not require distilled water replenishment during their service life.
