Detailed reasons and solutions for a hard-to-press brake pedal are as follows: 1. Related to pressing the brake before engine shutdown. The car's braking system operates at its maximum efficiency when the engine is running. When the engine is off, the brake booster pump becomes ineffective, and typically, pressing the brake pedal three times will deplete its remaining vacuum. Solution: Restart the engine. Once the engine is running, the brake booster pump will resume functioning, and the brake pedal will return to normal. 2. Leakage or malfunction of the car's brake booster pump. If you haven't pressed the brake pedal after the engine is off, or if you notice the brake pedal is hard to press while driving, it is likely due to a vacuum tube leak or blockage in the brake booster pump. Solution: If this issue is noticed before driving, take the car to a repair shop immediately for inspection. If it occurs while driving, the priority is to slow down and stop the vehicle. Try pressing the pedal multiple times to see if braking can be restored.

When to Use Vehicle Anti-Skid System?

Vehicle anti-skid systems are used during rainy days, icy road conditions, or snowy weather to effectively prevent the risk of skidding while driving. Typically, the anti-skid system in a vehicle is enabled by default and does not require manual activation. If it is turned off, it can be reactivated by pressing the EPS button. The Electronic Stability Program (ESP) is a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. The electronic stability program improves vehicle safety and handling. By analyzing vehicle driving state information from various sensors, the ESP system issues corrective commands to ABS, EBD, etc., to help maintain dynamic balance.

Where is the car thermostat installed?

Car thermostats are generally installed at the upper water outlet of the engine. The thermostat must maintain good technical condition; otherwise, it will seriously affect the normal operation of the engine. If the main valve of the thermostat opens too late, it will cause the engine to overheat. If the main valve opens too early, the engine's warm-up time will be too short, resulting in the engine temperature being too low. The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature to ensure the engine operates within an appropriate temperature range. This helps save energy, as engines consume more fuel at low temperatures and suffer greater damage, including the easy formation of carbon deposits and a series of related problems.

What is AECS?

AECS is the English abbreviation for Automotive-Electronic-Control-Systems, which translates to automotive electronic control systems in Chinese. Below is relevant information: Introduction 1: In terms of hardware structure, automotive electronic control systems generally consist of sensors, electronic control units (ECUs), and actuators. While the vehicle is in operation, various sensors continuously detect the operating conditions of the vehicle and transmit this information in real-time to the ECU through input interfaces. Introduction 2: The role of automotive electronic control systems is to receive various electrical signals, process them through computer analysis, and issue operational commands to various actuators, thereby enabling the vehicle to function properly.

How many points will be deducted and how much will be fined for not wearing a seat belt in the passenger seat?

Not wearing a seat belt in the passenger seat will result in a deduction of 1 point. Here is the relevant information: Precautions: The passenger seat is also the most dangerous seat in the entire car, so nowadays, cars will automatically sound an alarm if the passenger does not wear a seat belt. For the safety of yourself and others, it is essential to develop the good habit of wearing a seat belt. Regulations: According to the Road Traffic Safety Law, when a motor vehicle is in motion, passengers in the passenger seat should also use seat belts. The requirement for passengers to wear seat belts has been clearly stipulated in the old traffic regulations. Any passenger not wearing a seat belt in the passenger seat can be fined by the on-duty traffic police.

Can I switch from manual to automatic transmission during driving test?

It is not possible to change from manual to automatic transmission during the driving test, and the passed subjects cannot be altered. Once the driving license application materials have been accepted by the driving management office, all information is generated and cannot be modified. If you insist on switching from manual to automatic transmission during the driving test, you must cancel the original application and reapply for the driving test, which means all previous test results will be invalidated. Although the automatic transmission test does not assess clutch and gear control, it places higher demands on throttle control. In contrast, the manual transmission test does not focus on throttle control—as long as the clutch is managed well, you can shift from first to second gear using idle speed without pressing the accelerator. However, with an automatic transmission, pressing the accelerator too hard may cause the car to become unstable. You can use the manual mode (M mode), but even then, pressing the accelerator too hard will still trigger an automatic upshift. The main difference between manual and automatic transmission tests lies in the assessment of clutch control versus throttle control, while other aspects are largely similar. Additionally, a C2 license only permits driving automatic transmission vehicles. If you drive a manual transmission car with a C2 license and are caught by traffic police, it will be considered a mismatch with the permitted vehicle type, resulting in fines and demerit points. Moreover, in such cases, insurance companies may refuse to cover any accidents that occur.
