Reasons include: Excessive free travel of the vehicle's brake pedal. Insufficient air pressure in the air reservoir. Slippage of the air compressor drive belt. Brake line rupture or air leakage at the connections. This situation can lead to vehicle braking system failure, rendering the vehicle unable to operate and posing safety hazards. Below is relevant information: Insufficient braking air pressure: When a motor vehicle experiences insufficient braking air pressure, the brake control valve opens when the driver presses the brake pedal, connecting the air reservoir to the brake lines. Solution: Allow the air inside the reservoir to pass through the control valve into the vehicle's brake chamber. Only when the air pressure is sufficient can the brake adjusting arm rotate the wheel, enabling the vehicle to brake.

Will scratches on a new car without license plates affect the registration process?

If the vehicle has only been slightly scratched with no deformation or modifications to its appearance, it generally will not affect the registration process. This is because the inspection only involves photographing the vehicle identification number (VIN), engine number, and a full-body photo. However, if the new car is severely damaged, such as deformed front or rear bumpers, it may affect the registration. Documents required for new car registration: the owner's ID card and a copy, a local residence permit for non-local residents, the third copy of the purchase invoice (tax declaration copy), the original and a copy of the vehicle certificate, and for imported vehicles (whether standard imports or parallel imports), customs clearance documents, inspection certificates, and tax declaration forms are also needed. How to deal with scratches on a car: For minor scratches, you can use spray paint or apply a color-changing film for repair. Such repairs generally have minimal impact on the vehicle. For more severe scratches, sheet metal repair may be required. After purchasing a new car, you need to go through several procedures, including purchasing insurance, paying the purchase tax, vehicle inspection, and selecting a license plate number. Among these, purchasing insurance can be done simultaneously during the car purchase process.

Is there 95 diesel?

There is no 95 diesel, only 95 gasoline. Here is an introduction to diesel categories: 1. Diesel grades include 0#, 5#, 10#, -10#, -20#, -35#, and -50# diesel. 2. 5# diesel is suitable for temperatures above 8°C. 3. 0# diesel is suitable for temperatures between 4°C and 8°C. 4. -20# diesel is suitable for temperatures between -5°C and -14°C. 5. -35# diesel is suitable for temperatures between -14°C and -29°C. 6. -50# diesel is suitable for temperatures between -29°C and -44°C. Here is additional information about diesel: 1. Diesel is a light petroleum product, a complex mixture of hydrocarbons (with carbon atoms ranging from about 10 to 22). 2. It is mainly produced by blending diesel fractions obtained from processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking; it can also be produced from shale oil processing and coal liquefaction. 3. There are two main types of diesel: light diesel (boiling point range approximately 180–370°C) and heavy diesel (boiling point range approximately 350–410°C). Diesel is widely used in large vehicles, railway locomotives, and ships.

What is the fuel tank capacity of the Land Rover Range Rover?

The fuel tank capacity of the Land Rover Range Rover is 104 liters. Fuel tanks can be divided into two types: open tanks and closed tanks. They must have sufficient volume. To maintain oil cleanliness, the tank should have a sealed cover around it. More information about fuel tanks is as follows: Fuel tank functions: In addition to storing oil, the fuel tank in a hydraulic system also plays roles in heat dissipation, separating air bubbles from the oil, and precipitating impurities. Many auxiliary components are installed in the fuel tank, such as coolers, heaters, air filters, and liquid level gauges. Precautions for fuel tank use: The storage location of the fuel tank must be safe to prevent fires. The fuel tank should be placed separately in a visible area, appropriately far from diesel generator sets, and smoking is strictly prohibited. After refueling, the fuel tank cap should be locked to reduce fuel evaporation loss and maintain fuel cleanliness. Location of the car fuel tank: The fuel tank of a small car is generally located in the middle-rear part of the vehicle. However, depending on the model, some car fuel tanks are on the right side while others are on the left. The refueling port of the car fuel tank can be identified through the fuel gauge light on the car. There is an arrow symbol on the dashboard fuel gauge, and the direction the arrow points indicates the side where the fuel tank is located.

Differences Between the US Polo and the Chinese Polo?

The US Polo tends to have higher fuel consumption, while the Chinese Polo focuses more on refined interior details. Below is a detailed comparison of these two models: 1. Exterior: The headlights of the US Polo differ from the domestic version. Although the outer contours are the same, the internal structure is noticeably different, with variations in the distribution of low and high beams and the shape of the rear reflectors. The US Polo features a slender transparent cover on the upper outer part of the side mirrors, making the turn signals more visible when activated. 2. Features: The US Polo lacks an antenna. The rear window wiper, which in the latest domestic version is a conventional wiper, remains unchanged in the US model, indicating no plans for cost-cutting on this component in Europe. The rear window is generally flatter. 3. Safety: The arrangement of buttons on the dashboard to the right of the steering wheel in the US Polo differs from the domestic version. Seat heating, standard in the domestic Polo, is absent here. Additionally, a button to the right of the hazard lights button allows manual deactivation of the passenger-side airbag, enhancing safety for children in the front passenger seat. 4. Materials: The US Polo seats differ slightly in fabric choice and design from the domestic model. The method of adjusting the seatback also varies—the domestic Polo uses a spring-loaded handle, while the US Polo uses a rotary knob.
