The main raw materials of brake pads are adhesives, reinforcing fibers, fillers, and friction modifiers. Below is a detailed introduction about them: 1. Adhesives include resins and rubber powders: Their function is to liquefy and then solidify at high temperatures, turning the brake pad from powder into a solid block. 2. Reinforcing fibers serve as the skeleton of the brake pad: These include aramid fibers, steel wool fibers, copper fibers, mineral fibers, ceramic fibers, potassium titanate whiskers, etc. 3. Fillers: Different raw materials of brake pads have varying mesh sizes and diameters, requiring certain gaps to be filled. 4. Friction modifiers increase friction: These are materials harder than the brake disc, such as aluminum oxide, zirconium silicate, brown corundum, etc.

What is Audi's All-Weather Light?

All-weather light is called automatic sensing headlights. Function of all-weather light: It can automatically adjust the front lighting to reduce glare caused by the reflection of your own lights when driving on wet roads in rainy conditions. Simply put, it is a separate module integrated into the headlights, similar to fog lights. Principle of all-weather light: The working principle of automatic headlights is that electronic components such as photoresistors act as sensors to send electronic signals to the ECU, informing it whether to turn the headlights on or off, as well as to switch between high and low beams. The ECU controls the headlight switch and the change between high and low beams. When driving and encountering a sudden decrease in light, the ambient headlights will automatically turn on, and they will automatically turn off when the light is sufficient. Additionally, they will automatically switch between high and low beams during nighttime encounters with other vehicles.

Why Can't the Audi Car Key Be Pulled Out and the Car Won't Start?

Audi car key can't be pulled out and the car won't start because of the self-locking anti-theft function built into the steering column. Reasons why the key can't be pulled out: The cause of this situation is that the steering wheel was moved after the last time the car was turned off and the key was pulled out. To solve this, simply apply a little force while gently shaking the steering wheel left and right and turning the key at the same time. Principle of why the key can't be turned: After the key is pulled out, the mechanism controlled by the key no longer holds the lock tongue, and the lock tongue pops out under the action of the spring. If the steering wheel is turned at this time, the lock tongue will engage tightly with the lock groove on the steering column, making the key unable to turn.
