The handbrake, commonly known as the parking brake, is professionally referred to as an auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. As for the button on the handbrake, it is used to engage the handbrake, transmitting the pulling force through the steel cable to the rear brake drum or rear caliper, achieving the braking effect. More relevant information is as follows: 1. Function: The role of the handbrake is to tighten the brake shoes against the brake drum or disc after the vehicle has stopped, keeping the vehicle in a braked state to prevent dangerous movement. However, during high-speed driving, the braking force of the handbrake is minimal. If the driver pulls the handbrake while driving at high speed, it can easily cause the rear wheels to lock up, the cable to snap, and lead to vehicle skidding or even rollover. 2. Introduction: The professional term for the handbrake is auxiliary brake, which differs from the main brake in principle. It uses a steel cable connected to the rear brake shoes to apply braking force. The handbrake is a frequently used system, and proper usage ensures smoother operation in the future, especially for widely used mechanical handbrakes. It is best to follow the correct method of use.

Which Platform is Used for Court Auction Vehicles?

Vehicles seized by public security traffic management departments and people's courts are auctioned on platforms such as Taobao's [Ali Auction·Judicial] and JD.com's [JD Judicial Auction]. Although these are judicial auctions, they are mostly conducted by outsourcing companies with little direct involvement from public security departments or courts, so certain precautions should be taken during the auction. Here is relevant information: Court Auction Vehicles: These are vehicles that courts auction after legally seizing or confiscating them. Such vehicles may belong to defendants who lack funds to repay debts, where the court inventories the defendant's assets at the plaintiff's request and seizes or confiscates the defendant's vehicle as per its authority. Alternatively, the vehicle might be a criminal tool confiscated by the court and subsequently auctioned. Mortgaged Vehicles: The most common type involved in judicial auctions is mortgaged vehicles. For these, after a successful auction, the vehicle is only released from court seizure. The buyer must handle the transfer procedures themselves, while the vehicle's registration certificate ("big green book") and spare keys usually remain with the mortgage company. In most cases, after a successful court auction, the mortgage company will be notified and will proactively contact the winning bidder, who only needs to sign some documents at the mortgage company.

Do you drive on the left or right in France?

In France, vehicles drive on the right-hand side of the road. The custom of driving on the right originated in 18th-century France, primarily due to the country's well-developed stagecoach and freight transport services. France has numerous roundabouts, requiring drivers to be mindful of yielding promptly. Apart from this, it's similar to mainland China, with driving direction also on the right. Additionally, France adheres to the principle of pedestrian priority. Below is relevant information: French traffic lights: In France, traffic light poles are not installed at the opposite intersection for oncoming vehicles but are placed on the right-hand sidewalk. The poles feature two identical sets of red, yellow, and green signal lights. The larger set at the top is for vehicles approaching from a distance, while the set at the middle of the pole, aligned with the driver's line of sight, is for vehicles waiting at the intersection. Overtaking in France: Vehicles pass each other on the right and overtake on the left. When passing animal-drawn vehicles, two- or three-wheeled transport, pedestrians, riders, or livestock, a minimum side distance of 1 meter must be maintained. When overtaking tram vehicles on the road, sufficient space must be ensured between the vehicle and the roadside for overtaking on the right; overtaking on the left is prohibited. During overtaking, drivers must not use the left or middle lanes of the road.

What is the reason for the engine self-check light not illuminating and the car failing to start?

When the engine self-check light does not illuminate and the car fails to start, this situation is generally caused by a loose connection in the engine power circuit or corrosion in the ECU wiring due to water ingress. It is recommended to seek further inspection at a professional auto repair shop. When the car engine is not functioning properly and the self-diagnostic system does not output any fault codes, it is particularly necessary to rely on the operator's inspection and judgment to determine the nature and location of the fault. Below is relevant information: Sensor issues: Sensors include those for coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which can cause the engine self-check light to illuminate. Maintenance issues: Poor engine maintenance is the most common reason for the engine self-check light to illuminate. Vehicles have specific maintenance cycles, and if the owner does not adhere to the maintenance schedule, combined with poor driving habits, it will increase the burden on the engine's operation. Oil quality issues: Oil quality includes both fuel and engine oil. If the owner does not add the appropriate oil as required, prolonged use can lead to engine wear.

What does a court-auctioned car mean?

Court-auctioned cars are vehicles that have been legally seized or confiscated by the court and then put up for auction. These cars may belong to defendants who lack the funds to repay debts, and the court, upon the plaintiff's request, inventories the defendant's assets and seizes or confiscates the defendant's vehicles by authority. Alternatively, the vehicles might have been used as tools in criminal activities and were confiscated by the court before being auctioned. Below is relevant information: Mortgaged Vehicles: The most common type of vehicle involved in judicial auctions is mortgaged cars. For these vehicles, after a successful auction, the car is only released from court custody. The buyer still needs to complete the transfer process themselves, while the vehicle's title ("big green book") and spare keys remain with the mortgage company. In most cases, after a successful court auction, the mortgage company will be notified and will proactively contact the winning bidder. The buyer only needs to sign some paperwork at the mortgage company. Converted Commercial-to-Private Vehicles: Some auctioned vehicles are not mortgaged and may be in good condition overall, with prices that are very attractive compared to the used car market. The auction process may go smoothly, with no parking fees and acceptable levels of traffic violations. However, upon checking the vehicle registration, one might suddenly notice the words "Converted Commercial-to-Private" prominently displayed. These three words indicate that the car was once a commercial (operational) vehicle but later had its status changed to a private (non-operational) vehicle.

Will the original car paint crack grow larger if it splits?

Normally, it should not crack; cracking is an exceptional circumstance. Characteristics of car paint: Automotive paint must not only possess excellent mechanical properties, fullness, and high gloss but also demonstrate strong adhesion, high hardness, and scratch resistance. Additionally, it should exhibit good weather resistance, abrasion resistance, gloss retention, and superior resistance to gasoline, alcohol, acids, alkalis, and salt spray. Function of car paint: Automotive paint coating involves applying a thin film over the car's paint surface to maintain the glossiness and provide a physical protective layer, thereby safeguarding the paint.
