What to Do When Brake Discs Have Grooves?

When brake discs have grooves, it can lead to weakened braking, uneven friction, shaking during braking, and abnormal noises while braking. The brake discs should be polished or replaced. Specific details are as follows: 1. Remove the brake disc with minor grooves, place low-density sandpaper on a flat surface, and polish the brake disc horizontally and vertically on the sandpaper until it is smooth. 2. Brake discs are critical for safety. If the grooves are deep, polishing or grinding is not recommended, as polishing may not fully restore the grooved areas, and grinding can cause permanent damage to the brake disc. It is advisable to replace the brake disc immediately.

What are the instructions for light simulation?

Light simulation instructions are as follows: 1. Please switch the headlights to high beam. Lift the turn signal once. 2. Meeting with motor vehicles at night; Meeting with non-motor vehicles on narrow bridges at night; Following another vehicle closely at night. For all three instructions, lift the signal once to switch to low beam. These instructions are one of three options. 3. Passing through uncontrolled intersections at night; Passing through sharp curves or arched bridges at night; Passing through pedestrian crossings at night; Passing through slopes or arched bridges at night; Overtaking the vehicle ahead at night. For such instructions, lift the signal twice consecutively. 4. Vehicle breakdown on the road at night, obstructing traffic and difficult to move. This instruction requires turning off the headlights, keeping the width lights on, and pressing the hazard lights; Driving in foggy weather.

Are All Bumpers Made of Plastic?

Automobile bumpers are all made of plastic materials, and the reasons for this are as follows: 1. Relatively low cost. For economic considerations, using plastic automobile bumpers can save manufacturing costs in this aspect, allowing the funds to be allocated to areas such as material research and development to enhance the overall vehicle performance. Additionally, its strong plasticity makes it easy to design and produce. 2. For pedestrian protection. Current regulations in China offer almost zero protection for pedestrians. However, in European and American countries, pedestrian protection is mandated by regulations and must be considered. Using metal bumpers could cause fatal injuries to pedestrians' legs. Therefore, plastic bumpers have become the mainstream. 3. To achieve vehicle lightweighting. The application of plastic materials in automobile assemblies and components such as bumpers makes it possible to achieve the goal of vehicle lightweighting. Lightweighting of automobiles helps reduce fuel consumption and is beneficial for environmental protection.

How to Reset the Maintenance Light on a 2020 Geely Emgrand?

Press and hold the mute button on the steering wheel, then press the "MODE" button to enter the trip computer settings, and select maintenance reset. 1. The purpose of the maintenance light: Resetting the maintenance light is a necessary operation after car maintenance. Although the maintenance light is not directly related to the car's performance, resetting it promptly allows the owner to clearly understand the replacement time of car parts. 2. The setting of the maintenance light: The maintenance light is triggered by the manufacturer based on your vehicle's mileage of 5,000 km or 7,500 km, or generally after about half a year. If maintenance is not performed within this time, the maintenance light will also illuminate. The maintenance light is just a reference and does not determine anything, so there is no need to worry too much. However, it is best to go to a 4S shop for maintenance as soon as possible and turn off the maintenance light. If maintenance is not performed for a long time, the lubrication and cooling system of the engine may deteriorate, affecting the normal operation of the engine.

How to Remove Fog Inside the Car?

Fog inside the car can be removed through three methods: opening windows for air convection, using the air conditioning system, and applying defogging spray. Below are detailed introductions to these three methods for removing fog inside the car: 1. Opening windows for air convection: If the fog inside is not heavy, you can slightly open the windows on both sides to create air convection between the inside and outside of the car. This reduces the temperature difference, and the fog will gradually disappear. 2. Air conditioning system: Using the air conditioning system to remove fog is the most common method. Almost all cars nowadays have air vents located under the front windshield. Simply adjust the air conditioning to the appropriate setting, and the air blown out will help remove the fog. 3. Defogging spray: Spray the defogging agent onto the inner surface of the car glass and wipe it clean. This not only removes dirt from the glass but also forms a protective film that prevents moisture from condensing on the glass and forming a fog layer. One application can prevent fog for up to ten days.
