The main reason for soft brakes after changing brake fluid is: errors during the replacement process, which introduce air into the brake lines, requiring timely bleeding. The method for bleeding the brakes: 1. Two people are needed to cooperate to avoid mistakes. 2. First, one person presses the brake pedal 4-5 times, while the other loosens the bleeder screw on the brake caliper. 3. If there is indeed air in the brake line, some brake fluid and gas will be expelled. 4. Repeat the above steps until only brake fluid is expelled, indicating all air has been removed, then tighten the bleeder screw. 5. This will significantly improve the soft brake issue.

Can hybrid vehicles get green license plates in Shenzhen?

Shenzhen's oil-electric hybrid vehicles cannot obtain green license plates. The relevant information is as follows: Not classified as new energy vehicles: Currently in the domestic market, Toyota's oil-electric hybrid technology is not classified as a new energy vehicle and cannot receive green license plates or corresponding subsidies. However, plug-in hybrid technology can obtain exclusive plug-in hybrid green license plates. Currently, Toyota's only plug-in hybrid model is the Corolla PHEV. Related information: According to the latest news, the new RAV4 PHEV plug-in hybrid model will be produced at FAW Toyota's factory in Changchun, with an annual production capacity of approximately 16,200 units. The Avalon PHEV plug-in hybrid model will be produced at factories in Tianjin and Sichuan, with an annual production capacity of nearly 50,000 units.

Can I Claim Auto Damage Insurance for Broken Glass?

If it's only the car window glass that is broken, auto damage insurance won't cover it. You need separate glass breakage insurance for compensation. Relevant explanations are as follows: Reason: If the vehicle is involved in an accident causing damage to the entire car, including the window glass, then auto damage insurance can cover it. Additional note: The 2020 auto insurance reform added 7 responsibilities to auto damage insurance, one of which includes glass insurance. Therefore, now as long as the car owner has purchased auto damage insurance, they can enjoy glass insurance coverage. However, it's important to note that glass insurance does not cover the loss of car lights, sunroofs, or rearview mirrors. The loss of these parts needs to be borne by the car owner themselves.

Why is the battery level display on the electric tricycle dashboard abnormal?

There are two possible scenarios: one is that some batteries are faulty, and the other is that the battery connection wires are loose. Issues in other parts usually result in insufficient power display on the gauge. If the battery is out of power but the gauge still shows full, it's definitely a problem with the power gauge, most likely due to a new gauge being incompatible with the battery specifications. Here is some relevant information: Undersized battery: Check if the tricycle has strong power. If the power is average, it means the battery is undersized, and a larger capacity battery group should be used. Electric tricycles: With advantages such as strong applicability, flexibility, simple maintenance, convenient repairs, and low cost, they can easily navigate through narrow roads. Electric tricycles are equipped with a reverse switch, allowing for convenient reverse driving, which is very practical in narrow alleys and lanes, making both driving and parking very easy.

How much gear oil should be added to an electric four-wheel vehicle?

Add 100 milliliters at a time. Gear oil mainly refers to the lubricating oil for transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance characteristics. Gear oil primarily serves to lubricate gears and bearings, prevent wear and rust, and assist in heat dissipation for the gears. The functions of gear oil are as follows: Lubricating the transmission system: Reduces wear on gears and other moving parts, ensures normal operation of the transmission system, and extends service life. Cooling transmission components: During gear transmission, a significant amount of heat is generated due to friction between gear surfaces. If not dissipated in time, it can lead to localized high temperatures on the gear surfaces, and in severe cases, cause burning and adhesion.

Do Hybrid Cars Require Purchase Tax?

Whether hybrid cars require purchase tax depends on the specific model. If the hybrid car is a mild hybrid or medium hybrid model, purchase tax is required; if the vehicle is a plug-in hybrid, purchase tax is not required. Currently, there are three main categories of hybrid vehicles on the market: Mild hybrid models, represented by the Changan Eado Blue Core Edition and Geely Borui MHEV; medium hybrid models, represented by the Toyota Corolla, Toyota Levin, Honda CR-V Hybrid, and Beijing Hyundai Sonata Hybrid; and plug-in hybrid models, represented by the BYD Tang, BYD Qin, SAIC Roewe ei6, GAC Trumpchi GS4 Plug-in Hybrid, Great Wall WEY P8, and Geely Borui GE. The first category of hybrid vehicles mainly uses a 48V mild hybrid system, with battery capacities ranging from 1-2KWh. The second category represents typical hybrid vehicles, with larger battery capacities, but these models do not support pure electric driving. The third category of hybrid vehicles has battery capacities of around 10KWh, with a driving range of 50-100 kilometers. The purpose of exempting purchase tax for some hybrid vehicles: The exemption of purchase tax for some hybrid vehicles is a policy introduced by the government to encourage the production and sales of new energy vehicles. New energy sources like electricity and solar power are environmentally friendly energy sources.

Why does the Aoling CTS overheat when climbing slopes?

Aoling CTS overheats when climbing slopes due to insufficient engine coolant. Hazards of insufficient engine coolant: When climbing slopes, the engine power increases, generating more heat. If there are issues with heat dissipation at this time, the engine is highly prone to boiling over, which can damage the engine. Adding coolant can prevent such situations. Introduction to coolant: Engine coolant, also known as engine antifreeze, primarily ensures the normal and efficient operation of the engine. The coolant circulates within the engine's fuel tank, providing antifreeze, anti-rust, and anti-corrosion effects.
