What to Do When Oil Brakes Fail to Hold?

It is recommended to adjust the brakes at a 4S shop if the oil brakes fail to hold. The reasons for oil brakes failing to hold are as follows: 1. Daily operational errors. Most cases are due to the owner's daily operation and maintenance mistakes. Owners must regularly maintain the vehicle's braking system. Once braking issues arise, they should not be underestimated, and a thorough inspection at a 4S shop is necessary. 2. Vehicle overload. In summer, brakes may feel less responsive. The reason is that most cars use air conditioning in summer, and if the car's displacement is not large, it can easily increase the engine's load, affecting brake performance. 3. Brakes not holding firmly. Insufficient engine power. When the air conditioning is on, the brake booster pump cannot function properly during repeated braking by the owner.

How to Read Tire Size Specifications?

Tire size specifications can be viewed as follows: 1. International standard tire sizes are measured in millimeters, with each identifier representing tire width, aspect ratio, tire type, rim diameter, load index, and speed rating. 2. Example: Tire size 205/55R16-91W. 1. 205 indicates the tire width is 205mm. 2. 55 means the tire's section height to width ratio is 55%, which is the aspect ratio. 3. "R" stands for RADIAL, indicating it's a radial tire. 4. 16 shows the rim diameter is 16 inches. 5. 91 represents the load index. 6. W indicates the tire's permissible speed rating.

What is the difference between C1 and C2 driver's licenses?

The differences between C1 and C2 driver's licenses can be summarized in three aspects: From the perspective of vehicle types allowed to drive: C1 license permits driving: small cars (including C2, C3, C4 categories, specifically passenger vehicles with fewer than 9 seats such as sedans), as well as low-speed compact manual and automatic transmission trucks. C2 license permits driving: small automatic transmission cars and compact automatic transmission trucks. From the perspective of exam difficulty: C1 driving training is relatively more challenging and prone to mistakes. C2 automatic transmission vehicles are easier to learn and operate. During exams, fewer operations under stress lead to fewer errors, resulting in a higher overall pass rate. From the perspective of training costs: The registration fee for C1 is lower than that for C2. Age requirements: The minimum age limit for both C1 and C2 licenses is 18 years old, with no upper age limit. However, applicants aged 70 or above must pass tests assessing memory, judgment, and reaction abilities.

What does the car A/C mode mean?

Car A/C mode refers to air conditioning cooling. More information about the A/C button is as follows: 1. The A/C button is the air conditioning cooling button. When pressed, the car air conditioning starts working, and the air blown by the blower is cold. 2. The A/C button can control the switch of the compressor. The compressor is one of the main components of the car air conditioning cooling system, which can compress and deliver refrigerant vapor. 3. The A/C button is the control button to start the air conditioning compressor. The purpose of starting the air conditioning compressor is to cool. In winter, when the temperature is lower and the interior temperature drops faster, there is no need to turn on the A/C button.

Why do cars need regular maintenance?

Vehicle maintenance is to ensure that the vehicle is always in optimal working condition. Regular vehicle inspections can detect faults early and prevent problems before they occur. Each time you bring your car in for maintenance, the standard maintenance process includes tire tread inspection, chassis inspection (brake pads, brake discs, suspension arms, underbody, fluid leaks, etc.), lighting inspection, and engine fluid level inspection. The purpose of these inspections is to prevent problems before they arise. Below is an introduction to the relevant maintenance items: 1. Gasoline filter, air filter, and cabin air filter: Generally replaced every 20,000 kilometers. 2. Coolant (antifreeze) is recommended to be replaced every 20,000 kilometers. Insufficient coolant concentration can cause the engine to overheat. 3. Spark plugs are recommended to be replaced every 30,000-40,000 kilometers. Worn-out spark plugs can lead to insufficient power or engine vibration. 4. Transmission fluid is generally replaced every 50,000-60,000 kilometers. Some transmissions are maintenance-free for life and only require fluid top-ups as needed. Insufficient transmission fluid can cause gear shifting issues or even prevent shifting. There are multiple types of ATF (Automatic Transmission Fluid), and different types cannot be mixed. Before replacement, please refer to the owner's manual.

What to Do When a Key Breaks in the Lock?

Here are the solutions for when a key breaks inside the lock: 1. If the key breaks inside the lock and you have no tools at hand, immediately call a locksmith, though you will need to pay a fee. 2. Borrow a pair of pliers from a neighbor, provided that a small part of the broken key is still sticking out. Gently grip it with the pliers and carefully pull the broken key out. 3. If you have a small, pointed tweezer, insert it into the lock to remove the broken key. 4. Apply some 502 glue to the broken end of the key and quickly press it against the key inside the lock. Wait for five minutes, then gently pull—the broken key might come out with it.
