The reasons for hard braking include issues with the brake booster pump, foreign objects adhering to the brake pads and calipers, and the vehicle's ABS system engaging. In case of hard braking, you can ease off the accelerator to slow down and try pressing the brake pedal several times to see if braking force can be restored. Causes of hard braking: Issues with the brake booster pump. If the brake suddenly becomes hard while driving, it may be due to a vacuum tube leak or blockage in the brake booster pump. In such cases, the vehicle should be stopped immediately for inspection, and replacement may be necessary if required. If the brake becomes hard after the engine is turned off, it is usually because the brake pedal was pressed continuously after the engine was turned off, causing the vacuum force of the brake booster pump to be depleted. In this situation, simply restarting the engine to allow the brake booster pump to resume operation will resolve the issue. Foreign objects adhering to the brake pads and calipers. If there are foreign objects on the brake pads or calipers, the friction caused by these objects during braking may create a sensation of hard braking. This issue can be resolved by cleaning the affected parts. Vehicle ABS system engagement. During emergency braking, the vehicle's ABS system intervenes to prevent wheel lock-up and loss of control, which can lead to accidents. This intervention causes a rebound effect in the brake pedal. This is a normal phenomenon, and gently pressing the brake pedal again will restore normal braking.

What does 'one oil' mean?

'One oil' represents one liter of oil. Generally, when people say 'a few oils,' they are referring to how many liters of oil a car consumes per 100 kilometers. If there are no bad driving habits during the journey, consuming around 7 liters of oil per 100 kilometers is considered relatively fuel-efficient. For SUV models, consuming around 10 to 11 liters per 100 kilometers is also considered fuel-efficient. Methods to improve fuel efficiency are as follows: 1. Drive at a constant speed: Control the vehicle's speed and avoid sudden braking; 2. Avoid opening windows at high speeds: Opening windows at high speeds increases fuel consumption; 3. Regularly check tire pressure to ensure it is correct: Both under-inflation and over-inflation can increase fuel consumption, so it's important to check tire pressure periodically; 4. Pay attention to transmission maintenance: Always use the correct transmission oil for your vehicle. Transmission oil not only lubricates but also helps in torque transmission, so it should be replaced regularly.

How to Calculate Purchase Tax for 250cc Motorcycles?

Motorcycles with an engine displacement not exceeding 150cc are exempt from purchase tax. For motorcycles with an engine displacement exceeding 150cc, the payable tax amount is calculated by multiplying the taxable vehicle's price by the tax rate (for example, if a consumer buys a motorcycle priced at 10,000 yuan, the tax is calculated after deducting the VAT portion at a rate of 10%. The calculation formula is 10,000 ÷ 1.17 × 0.1 = 999.9 yuan). The taxable objects for motorcycles are as follows: 1. Light motorcycles: Motor vehicles with a maximum design speed not exceeding 50km/h and an engine cylinder total displacement not exceeding 50cc, having two or three wheels; 2. Two-wheeled motorcycles: Motor vehicles with a maximum design speed exceeding 50km/h or an engine cylinder total displacement exceeding 50cc, having two wheels; 3. Three-wheeled motorcycles: Motor vehicles with a maximum design speed exceeding 50km/h, an engine cylinder total displacement exceeding 50cc, and an unladen weight not exceeding 400kg, having three wheels.

Are parking lot ETC and highway ETC the same?

Parking lot ETC and highway ETC are the same. The following are specific explanations about ETC: 1. Meaning: ETC is an electronic toll collection system that does not require stopping. The ETC dedicated lane is used for vehicles equipped with ETC on-board units, adopting electronic toll collection methods. 2. Development Status: ETC is an electronic automatic toll collection system for highways, bridges, and tunnels that is being actively developed and promoted internationally. This technology has a long development history abroad, and electronic toll collection systems in many countries and regions such as the United States and Europe have been partially networked and gradually formed economies of scale. In China, the highway toll collection system, which mainly uses IC cards and magnetic cards as media and adopts manual toll collection methods, is undoubtedly influenced by this trend.

Can I Apply for ETC Without a Driver's License?

You can apply for ETC without a driver's license. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the owner needs to provide the original valid ID card, the original and a copy of the vehicle registration certificate, and the page of the registration certificate with the latest annual inspection stamp. If applying on behalf of someone else, the agent's original valid ID card is also required. If applying for ETC through major bank branches, you also need to prepare a debit card or credit card from the corresponding bank. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding ETC with a debit card. The principle of ETC deduction: There will be one or more ETC lanes on highways. Through microwave dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane of the toll station, computer networking technology is used to conduct background settlement with the bank, achieving the goal of paying tolls without stopping at the toll station. All this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Green and low-carbon, vehicles pass through the toll station without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on toll fees; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly proposed in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" to "basically achieve interoperability of transportation smart cards in key urban agglomerations by 2020 and significantly increase the proportion of vehicles equipped with ETC," and set a clear target in the main indicators of the "13th Five-Year" comprehensive transportation development to "achieve a 50% ETC usage rate for road passenger vehicles by 2020." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a stopped vehicle ahead, to prevent the ETC device of the vehicle ahead from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatically sensing and paying for the vehicle ahead. The recognition speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in failed fee deductions. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not due to human factors, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also result in failed fee deductions. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card payment. Poor sensing due to excessively thick windshields. Especially for vehicles that have had accidents and had their windshields replaced or for those who have modified their front windshields, extra attention is needed.
