Why Do Car Brake Pads Make Noise?

The reasons why car brake pads make noise are: 1. Use of low-quality or overly hard brake pads; 2. Presence of sand or foreign objects between the brake pads and brake discs; 3. Severe wear of the brake discs; 4. Brake pad warning. Brake pads, also known as brake linings, are critical safety components in a car's braking system. The effectiveness of all braking actions is decisively determined by the brake pads. Brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT4 furnace temperature tracker to ensure the temperature distribution during coating meets quality standards. The heat insulation layer is made of non-heat-conducting materials to provide thermal insulation.

What does airbag mean?

Airbag in a car refers to the passenger airbag. Here is a detailed introduction to the automotive airbag system: 1. Function: When a car collision occurs, the airbag can evenly distribute the impact force on the head and chest, preventing direct contact between the passenger's body and the car body, 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 even 80% of passengers were not wearing seat belts. 2. Supplementary safety device: The automotive airbag system is a supplementary safety system, usually serving as an auxiliary safety device to seat belts. Airbags are used in conjunction with seat belts.

Why is water coming out of the car's exhaust pipe?

The reason for water coming out of the car's exhaust pipe is: During driving, gasoline undergoes complete combustion inside the engine, producing water and carbon dioxide after complete combustion. At high temperatures, water is colorless and transparent water vapor. When the temperature drops below 100 degrees Celsius, the water vapor condenses into water and drips from the exhaust pipe. The conditions for water to come out of the car's exhaust pipe are: 1. The air-fuel mixture ratio must meet the normal value; 2. The engine cylinder pressure is normal, with no significant wear inside the engine block or negligible wear, and the cylinder liners and sealing ring components are intact; 3. The exhaust temperature is normal, with most of the heat generated by the engine remaining in the cylinders.
