Is Rusty Brake Pads a Sign of a New Car?

1 Answers

It is normal for new car brake pads to have rust, and rust on the vehicle's brake discs is a common phenomenon that does not affect the normal use of the car. Moreover, it is not a standard for checking whether a vehicle is new. However, car owners should regularly inspect the condition of the brake pads and replace them in a timely manner. Below are some considerations when purchasing brake pads: 1. Four Key Points to Check: (1) Check the friction coefficient. The friction coefficient determines the basic braking torque of the brake pads. If it is too high, it can cause wheel lock-up during braking, loss of directional control, and overheating of the pads. If it is too low, the braking distance may be excessively long. (2) Check safety. Brake pads generate instantaneous high temperatures during braking, especially during high-speed driving or emergency braking. Under high temperatures, the friction coefficient of the pads may decrease. (3) Check comfort, including braking feel, noise, dust, smoke, and odors, which are direct reflections of friction performance. (4) Check lifespan. Typically, brake pads can ensure a service life of 30,000 kilometers. 2. Two Choices: (1) Choose automotive brake pads produced by reputable manufacturers, with license numbers, specified friction coefficients, and compliance with standards. The packaging should include a certificate of conformity, production batch number, and production date. (2) Choose to have them installed by professionals at specialized repair shops.

How to Repair a Faulty Car Door Lock?

Solutions for a damaged car door lock are as follows: 1. First, check if the lock actuator is functioning. If there is no movement, it is likely due to poor contact in the central control system wiring, which requires inspection and repair at a service center. 2. If the actuator is functioning, the issue may be excessive resistance in the lock mechanism, often caused by rust. In this case, replacing the lock actuator should resolve the problem. 3. Another possibility is that the position of the door lock motor's latch has shifted. This can be fixed by adjusting it at a repair shop. 4. Lastly, the door lock motor itself may be damaged or lack sufficient pulling force, necessitating its replacement.

What Causes Insufficient Engine Oil Pressure?

The reasons for insufficient engine oil pressure are as follows: 1. Oil contamination or thickening due to prolonged use: This prevents the oil pump from smoothly drawing in and pumping out oil, resulting in low oil pressure. 2. Excessive wear of components: For example, excessive clearance between the crankshaft and bearings, or malfunction of the pressure relief valve due to weak springs or damaged steel balls, can reduce oil intake and output, leading to low or no oil pressure. 3. Faulty oil pressure sensor, gauge, or circuit: This can cause low oil pressure. 4. Oil thinning: Leakage through the gaps between engine friction pairs can result in low oil pressure.

Must the first insurance be purchased at the 4S store where the car was bought?

When buying a car for the first time, insurance does not have to be purchased at the 4S store. The details are as follows: 1. According to Article 9 of the Consumer Rights Protection Law: Consumers have the right to independently choose the operators who provide goods or services, independently select the types of goods or service methods, and independently decide whether to purchase any product or accept any service. 2. During the sales process, merchants can suggest handling insurance, but they cannot force consumers to purchase it. 3. When consumers independently choose goods or services, they have the right to compare, evaluate, and select.

What does the eco light on the car mean?

When the eco indicator light on the vehicle's dashboard is illuminated, it indicates that the car's economy mode has been activated. Eco is an English abbreviation formed from the words Ecology, Conservation, and Optimization. The Eco mode is further divided into active eco driving mode and passive eco driving mode. Eco mode can be categorized into active and passive types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to enable it. When the driver presses the Eco mode switch, the dashboard indicator light turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The passive Eco mode does not have a dedicated button; when the dashboard Eco indicator light is on, it merely serves as a reminder function. The Eco system automatically evaluates your driving behavior, and if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most cars use the active Eco driving mode, which means they have their own switch button. Therefore, we can enable Eco mode during daily driving. Additionally, Eco mode usually becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car will prioritize speed, causing the Eco mode to automatically deactivate. When idling or in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit will prioritize ensuring sufficient power to drive the vehicle, and the Eco mode will not function in this case either.

Does the Emgrand GL manual transmission have cruise control?

Emgrand GL manual transmission does not have cruise control. Only the automatic transmission models are equipped with it. The relevant introduction to cruise control is as follows: How cruise control works: The cruise control module reads the pulse signal from the speed sensor and compares it with the set speed, then issues commands to the servo mechanism to adjust the throttle opening, increasing or decreasing it to maintain the vehicle at the set speed. How to use cruise control: Press CRUISE to activate cruise control. Briefly press the RES+ or SET- adjustment button once to increase or decrease the set cruise speed by 1km/h. Briefly press the SET- button to set the current speed as the cruise speed.

How to Deal with Sunroof Noise?

Solutions for sunroof noise are as follows: 1. Wipe the sunroof slide rail with a soft cotton cloth. 2. Apply butter to the rail. 3. For rubber or plastic parts, clean the surface and apply talcum powder for protection. 4. Regularly check the sunroof and tighten any loose screws. Here are the reasons for sunroof noise: 1. Aging of the sunroof rubber seal or sealing ring. 2. Loose sunroof screws. 3. Dust particles in the sunroof slide rail. The functions of the sunroof are as follows: 1. Enhance the ventilation inside the car. 2. Refresh the air inside the car. 3. In case of an emergency where the door cannot be used for escape, one can exit through the sunroof.
