How Long Does It Take to Replace Brake Pads?

Replacing a set of brake pads alone takes about 1 hour, which is both time-consuming and labor-intensive. The specific steps are as follows: 1. When replacing brake pads, the car needs to be lifted and the tires removed. 2. Remove the screws of the brake caliper, take off the brake caliper, and remove the old brake pads. 3. Push the brake piston back in and install the new brake pads. 4. Reinstall the brake caliper, tighten the caliper screws to the required torque, and then reinstall the tire. Precautions: 1. After replacing the brake pads on both sides, you may notice brake fluid overflowing from the brake fluid reservoir. In this case, you need to press the brake pedal several times to keep the fluid level between max and min. 2. Pressing the brake pedal is to eliminate the gap between the brake pads and the brake disc and to reset the wheel cylinder piston. 3. Generally, new brake pads require a break-in period. Only after this period can they perform their braking function more effectively.

What does the exclamation mark light on the dashboard mean?

When an exclamation mark appears on the car dashboard, there are five possible scenarios: general faults, automatic transmission faults, braking system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cutoff system intervention or failure, external light faults, or engine oil pressure sensor faults. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant level below the normal range. Transmission oil should be replaced promptly. Braking System Fault: A circle with parentheses and an exclamation mark in the middle represents a braking system warning, typically indicating a braking system malfunction or low brake fluid level. Immediate inspection of the braking system is required to avoid accidents. Abnormal Tire Pressure: A horizontal line with parentheses and an exclamation mark below represents the tire pressure monitoring warning light. This light illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

Can Auto Hold and Auto Start-Stop Be Used Simultaneously?

Auto Hold is used to stabilize the vehicle after parking, while Auto Start-Stop is used for stopping and starting the engine. These are two completely different functions and can be used together. Below are detailed introductions to the Auto Hold and Auto Start-Stop functions: 1. Auto Start-Stop: When the vehicle comes to a temporary stop during driving, the engine automatically shuts off. When it's time to move forward, the engine automatically restarts. Working Principle: When the driver stops the vehicle by pressing the brake pedal and shifting to neutral, the Auto Start-Stop system automatically detects that the engine is idling and not in gear. The wheel speed sensor of the locking system shows zero, and the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically shuts off. When the driver releases the brake or turns the steering wheel, the engine automatically restarts. 2. Auto Hold: This is an automatic braking function. When activated, it automatically applies the handbrake for the driver at traffic lights to prevent rolling back. Working Principle: During driving, temporary braking and long-term braking after stopping are integrated, and parking braking is achieved through electronic control.

What does Driving SOS mean?

Driving SOS refers to the vehicle self-rescue system. Below is more information about it: 1. SOS is the international Morse code distress signal, not an abbreviation of a single word. Nowadays, vehicles are generally equipped with a one-touch SOS call button. The SOS system in cars is a vehicle self-rescue system. It is an emergency system designed to quickly seek rescue assistance when the vehicle encounters a malfunction, an accident, or faces a dangerous and sudden situation. 2. In case of an emergency, pressing the SOS button for more than 2 seconds will automatically activate the in-vehicle connected system. The system uses the manufacturer's built-in emergency alert feature, which can only be triggered by the connected system to send an emergency alert and locate the vehicle. For example, if a malfunction occurs, you can contact roadside rescue services through Driving SOS to seek appropriate help and services.

Is a car DCT an automatic transmission?

Yes, a car DCT is an automatic transmission, which refers to a dual-clutch transmission. The principle of DCT is based on two sets of manual transmissions, where adjacent gears are typically arranged alternately on the two sets of gears. Two clutches separately control the connection and disconnection of the two sets of gears with the engine. The dual-clutch automatic transmission is a mechanical automatic transmission that retains all the advantages of AMT. However, its power transmission is achieved through two clutches connecting two input shafts, with adjacent passive gears alternately meshing with the gears on the two input shafts. By coordinating the control of the two clutches, it can achieve gear ratio changes without interrupting power transmission, thereby reducing shift time and effectively improving shift quality.
