Poor braking after replacing brake pads occurs because the surface of the new brake pads is relatively flat, while the contact surface on the brake disc is very uneven. This results in a very small contact area between them. Additionally, when the brakes are applied, the brake pads undergo significant deformation, leading to what is known as poor braking. Here is some relevant information: 1. Generally, new brake pads require a break-in period of 200 kilometers to achieve optimal braking performance. Therefore, vehicles with newly replaced brake pads should be driven cautiously. 2. Break-in method for new brake pads: After installing new brake pads, find a road with good conditions, accelerate to 100 km/h, then gently apply the brakes to reduce the speed to around 10-20 km/h. Then, release the brakes and drive for about 5 kilometers to allow the brake pads to cool slightly. Repeat this process approximately 10 times.

What does Mazda6 DSC mean?

DSC refers to the Dynamic Stability Control system in Mazda vehicles. More details about DSC are as follows: 1. Function of DSC: This system automatically controls the vehicle when it detects skidding during driving. By coordinating with TCS and 4W-ABS, it optimally controls engine output and four-wheel braking force to effectively suppress vehicle skidding. Even when cornering on slippery roads or avoiding obstacles in emergency situations, it helps maintain stable vehicle posture for safe driving. 2. DSC warning light: When the DSC warning light on the dashboard illuminates, it indicates a possible malfunction in the stability control system, and DSC is not operational. There are various reasons for the DSC warning light to come on, including sensor or wiring faults, deviations in signals from the electronic control unit, or accidental pressing of the DSC off button.

What is the fuel consumption of the 6th generation Camry?

Camry's actual fuel consumption is approximately 7.5 liters per 100 kilometers in urban areas and about 6 liters on highways. Here are the specific details: 1. Rapid acceleration and sudden braking: These actions can increase fuel consumption by 5%~30% compared to normal driving. It is essential to avoid sudden braking or acceleration while driving, as it not only raises fuel consumption but also accelerates vehicle wear. 2. Prolonged idling: Many drivers often let the vehicle idle for a while after starting to warm it up. Since the car consumes energy as long as it is running, this only increases fuel consumption. 3. Vehicle maintenance: Many drivers overlook the importance of car maintenance. Poor maintenance can also lead to increased fuel consumption. For example, a dirty air filter or deteriorated engine oil can cause incomplete fuel combustion, resulting in higher fuel consumption.

How to Retake the Driving Test After License Revocation?

License revocation retake method: After the driver's license is revoked, reapplying requires retaking the test, which is treated as applying for a motor vehicle driver's license for the first time. The applicant needs to bring their identity proof and a medical condition certificate issued by a county-level or higher medical institution (or a military medical institution at the regimental level or above) to the vehicle management office to fill out an application form. Then, the office will organize and arrange the test. A driver's license is a document that motor vehicle drivers are legally required to obtain. By learning to drive a motor vehicle and mastering basic knowledge of traffic regulations and driving skills, one can pass the test and obtain the motor vehicle license. The driver's license allows for nationwide testing and taking different test subjects in different locations.

How to Find Vehicle Owner Information with a License Plate Number?

Ordinary people cannot look up vehicle owner information online based on license plate numbers, as this is considered private information and unauthorized access is prohibited. However, traffic police and law enforcement officers can query owner details using the plate number. The first character of a Chinese license plate is a Chinese character representing the abbreviated name of the province where the vehicle is registered. The second character is an English letter indicating the prefecture-level city code, followed by a five-digit serial number. The functions of a license plate include: 1. Numbering and registering vehicle information; 2. Identifying the vehicle's registered region; 3. Enabling authorities to trace the owner and registration details. Types of license plates: 1. White plates indicate military or police vehicles; 2. Blue plates represent ordinary small passenger vehicles with fewer than 7 seats; 3. Yellow plates are for standard large vehicles; 4. Black plates denote vehicles registered to foreign enterprises.

What type of engine oil is suitable for Ford Fiesta?

Use engine oil labeled as 5W30 or 5W40. Below are the detailed instructions: 1. Maintenance: Routine maintenance primarily involves changing the engine oil and oil filter. Generally, clean the air filter approximately every 5,000 km (for normal road conditions), with shorter intervals required for dusty roads. Replace both the air filter and fuel filter around 15,000 to 20,000 km. For manual transmission vehicles, conduct corresponding safety checks on other components after 30,000 km. 2. High-quality engine oil: As the engine undergoes normal wear and internal clearances increase, higher-quality engine oil is indeed necessary. Currently, GT Magic Red engine oil is widely used. Its Group IV PAO base oil inherently offers excellent quality, and with the addition of liquid molybdenum, it provides superior anti-wear protection, ensuring timely lubrication and safeguarding all engine components.
