How to Distinguish Between Inner and Outer Brake Pads?

Methods to distinguish between inner and outer brake pads: The inner side of the brake pad has a friction block, while the outer side does not. Brake pads, also known as brake linings, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction block within them bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. The braking process is essentially the conversion of kinetic energy into thermal energy. Brake pads, brake discs, and brake fluid all require regular replacement. Many car owners tend to overlook brake fluid during maintenance. Brake fluid is a liquid that easily absorbs moisture. If the water content in the brake fluid is too high, it can lead to reduced braking force and extended braking distance. When the water content in the brake fluid reaches 3%, it should be replaced immediately. It is essential to have brake fluid replaced by professionals, and after replacement, the air in the brake system pipelines should be bled out; otherwise, it may affect braking performance.

How to Drive Safely on Snowy and Icy Roads?

When driving on snowy or icy roads, maintain a slow and steady speed, and avoid sudden braking or sharp steering wheel movements. Reduce speed in advance and, when conditions permit, increase the turning radius appropriately to prevent skidding. If skidding occurs, immediately release the brakes, stabilize or slightly reduce the throttle, and steer the front wheels in the direction of the skid. Once the skid is corrected, resume normal driving.

What should you do when temporarily parking a motor vehicle on the road?

First, check if there are any parking restriction signs in this area to determine whether parking is prohibited or time-limited. Temporary parking is only allowed in time-limited parking zones. Then, reduce your speed, turn on the right turn signal, and check the right rearview mirror to see if there are any vehicles or pedestrians behind you on the right side. After pulling over to the side of the road and stopping the vehicle securely, engage the handbrake or press the parking button.

What are the consequences of driving a vehicle that does not match the driver's license?

Driving a vehicle that does not match the driver's license is generally treated as unlicensed driving by traffic police. Driving an electric tricycle with a C1 license is considered a mismatch between the vehicle and the permitted driving category. Driving a vehicle that does not match the permitted driving category will result in a fine for unlicensed driving and may also lead to detention. A C1 license for small cars allows the holder to drive manual or automatic transmission vehicles with 9 seats (including 9 seats) or fewer, such as small and micro passenger cars and light vehicles.

What's the Difference Between Dual Clutch and Automatic Transmission?

The differences between dual clutch and automatic transmission are as follows: 1. Different Principles Automatic transmission uses a computer to control hydraulic oil to push pistons for gear shifting based on throttle size, vehicle speed, and throttle opening; dual clutch is equipped with two clutches, one controlling gears 1, 3, and 5, and the other controlling gears 2, 4, and 6. 2. Different Operation Methods Automatic transmission does not require the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions; dual clutch combines manual and automatic gear shifting, allowing the driver to either just press the accelerator for automatic shifting or manually change gears.
