Here are the differences between brake pads and brake discs: 1. The brake disc, also known as the brake rotor, is a disc-shaped metal component with numerous ventilation holes. During driving, the brake disc rotates with the wheel. When the brake caliper clamps the brake disc, it generates braking force, slowing down or stopping the vehicle. Brake discs offer superior braking performance and are easier to maintain compared to drum brakes. 2. The brake pad, also called the brake lining, is made of materials such as ceramic, metal, or carbon fiber and is installed inside the brake caliper. The quality of the brake pad determines the braking effectiveness. Composed of a steel plate, adhesive heat insulation layer, and friction material, the brake pad is pressed against the brake disc or drum when the brake is applied, creating friction to decelerate or stop the vehicle.

When to Use High Beams While Driving?

High beams should be used while driving on highways or in rural areas without streetlights. There is no need to use high beams on urban roads as city streets generally have good lighting conditions. The high angle of high beams can easily dazzle oncoming drivers and pedestrians, impairing their vision and creating unsafe conditions, which is also considered impolite driving behavior. If other vehicles frequently flash their lights at you, promptly check whether your high beams are on. Alternating between high and low beams serves as a form of light communication with various meanings, such as alerting vehicles at intersections to be cautious, signaling for nighttime overtaking, or reminding oncoming vehicles to switch to low beams.

Which damping setting is the most comfortable for a 32-stage adjustable suspension?

There is no specific quantitative standard for this; it depends on the actual vehicle performance and personal preferences. After all, some people prefer stiffer suspensions while others favor more comfortable tuning. Additionally, the vehicle's weight distribution and chassis quality also affect the tuning parameters of the coilover suspension. The optimal setting can only be determined through actual testing. Extension: Adjusting coilover suspension damping: Coilover suspensions mainly allow adjustment of three parameters: body height, spring stiffness, and damping. Body height affects the vehicle's ground clearance, so this can be adjusted according to personal preference. The key adjustments are spring stiffness and damping.

Overview: A car engine is the device that provides power to a vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. 2. Others: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston movement and outputting power externally. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have low manufacturing costs. Diesel engines have a high compression ratio, excellent thermal efficiency, and better fuel economy and emission performance than gasoline engines.
