Why Does the Car Brake Light Stay On?

What are the signs before a car's brakes fail?

Signs include body shaking when braking during driving, the brake pedal not returning to its position immediately, uneven braking when applying the brakes, and the car responding more slowly than usual when braking. Below is an introduction related to car brakes: 1. Introduction to brakes: Braking, also known as stopping, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other means of transport, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base to generate braking torque under external force. The braking device, also known as a decelerator, is a mechanical braking device that can slow down the speed. 2. Classification of brakes: Drum brakes, advantages of drum brakes, disadvantages of drum brakes, disc brakes, etc.

What Does a Half Shaft Abnormal Noise Sound Like?

The abnormal noise from a half shaft is a metallic friction sound. Due to the small contact area between the half shaft and the drive wheel connection point, the metallic friction sound becomes particularly noticeable under heavy load. Additionally, there is a gap between the half shaft and the wheel hub spline caused by the dust cover, leading to sticky friction at the contact surfaces of the half shaft and wheel hub, which also generates abnormal noise. The half shaft in a car is essentially the drive shaft. When the car is moving and needs to turn, the rotation speeds of the two wheels differ, requiring a differential on the drive shaft. The differential is the device that allows the two wheels to rotate at different speeds, with the half shaft connected to the differential and then to the wheels.

What are the two types of non-scheduled vehicle maintenance?

China's maintenance system is divided into three categories: routine maintenance, scheduled maintenance, and non-scheduled maintenance. Below is the relevant information: 1. Primary maintenance: Centered on tightening and lubrication, primary maintenance addresses certain weak points that emerge after a vehicle has been driven a certain mileage, ensuring the vehicle maintains the technical conditions for continued normal operation. 2. Secondary maintenance: Centered on inspection, adjustment, and lubrication, secondary maintenance involves a more thorough and detailed comprehensive inspection and adjustment of the vehicle. Its purpose is to ensure the vehicle can maintain good operational performance over an extended period.

What does grinding off the serial number mean for a vehicle?

Grinding off the serial number refers to vehicles sold through unofficial channels or cross-regional sales, where the VIN (Vehicle Identification Number) is intentionally erased to avoid accountability for parallel imports by the manufacturer. Additional details are as follows: Generally, purchasing from reputable stores ensures genuine products with qualified quality and craftsmanship, and the store will provide its own warranty. However, there is still a possibility of substandard or counterfeit products. The main difference lies in whether the warranty is honored, as large authorized dealers often only provide warranties for vehicles sold locally. If you possess basic maintenance skills, a vehicle with a ground-off serial number can still be an option. If consumers purchase a 'ground-off serial number' product, they can request the manufacturer to issue a certificate proving the product's quality as unqualified, and the manufacturer should provide the corresponding documentation.

What does airbag mean?

In a car, airbag refers to the passenger safety airbag. Here are the specific details about the automotive airbag system: 1. Function: During a collision, the airbag distributes the impact force evenly across the head and chest, preventing direct contact between the passenger's body and the vehicle structure, thereby reducing the likelihood of injury. According to statistics, in frontal collisions involving vehicles equipped with airbags, the severity of passenger injuries can be reduced by up to 64%, and in some cases, 80% of passengers were not wearing seat belts. 2. Supplementary Safety Device: The automotive airbag system is a supplementary safety system, typically serving as an additional safety measure alongside seat belts. Airbags are designed to be used in conjunction with seat belts.

Is a Fire Extinguisher Mandatory for Vehicles on Highways?

Currently, it is not mandatory for vehicles to carry a fire extinguisher when driving on highways in China. The "Road Traffic Safety Law" of China does not enforce the requirement for passenger cars to be equipped with safety facilities such as fire extinguishers, nor are there corresponding penalty provisions. Below are relevant details: 1. Vehicle Fire Extinguisher: Specifically designed for vehicle fire suppression, it includes two main types: non-storage pressure suspension-type ultra-fine dry powder automatic fire extinguishing devices for vehicles, and storage pressure suspension-type ultra-fine dry powder automatic fire extinguishing devices for compact cars. Currently, portable fire extinguishers are predominantly used for vehicle fire protection. 2. Precautions: In case of a fire on the highway, it is crucial to report to the authorities promptly to avoid casualties.
