Braking with a jerking sensation is due to significant wear of brake pads, issues with transmission gear programming, internal contamination and impurities in the transmission, or poor transmission cooling. The specific reasons are as follows: Significant wear of brake pads: Severe wear or aging of the car's brake pads can cause a jerking sensation when braking. It is advisable to replace the brake pads promptly. Transmission gear programming issues: The transmission control system needs to be reprogrammed. Internal contamination and impurities in the transmission: Contamination or impurities inside the transmission can prevent effective regulation of transmission oil pressure, leading to jerking. Poor transmission cooling: This can cause abnormal high temperatures in the transmission, affecting the performance of the transmission oil. If the temperature exceeds 120 degrees Celsius, the rubber sealing materials in the transmission can harden, leading to oil leaks, which in turn affect oil pressure and cause jerking.

I've been driving for over a decade and often experience jerky sensations when braking, which is quite common—it's probably due to uneven brake pad wear. Last time my car shook violently during emergency braking, so I took it to the repair shop. They found the brake pads were nearly worn out, with uneven surfaces. The mechanic also checked the tires and said unbalanced tire pressure could cause unstable braking, especially noticeable as more pronounced bumps at high speeds. It's recommended to schedule regular maintenance, checking brake pad thickness and tire condition at least every six months. If the jerking becomes more frequent, don't ignore it—get it fixed promptly to avoid accidents in emergencies. Also, consider weather effects; if braking feels abnormal on slippery roads, it might be the ABS system working, but that's not the primary cause.

What is the purpose of an automotive thermostat?

The purpose of an automotive thermostat is to function as a valve controlling the flow path of engine coolant. It automatically regulates the amount of water entering the radiator based on the coolant temperature, thereby playing a role in energy conservation. The thermostat must maintain good working condition; otherwise, it will seriously affect the normal operation of the engine. If the thermostat opens too late or fails to open, it can cause the engine to overheat. Conversely, if it opens too early, it prolongs the engine warm-up time, resulting in the engine temperature being too low. Methods for detecting thermostat faults in automobiles include: 1. When the coolant temperature exceeds 110 degrees, stop the car, turn off the engine, open the engine hood, and feel the upper and lower radiator hoses for a significant temperature difference; 2. If the engine does not reach normal operating temperature for an extended period, stop the car and allow the engine temperature to drop to ambient temperature. Then, restart the engine and observe the dashboard. When the temperature rises to around 70 degrees, stop the car, turn off the engine, open the engine hood, and feel the upper and lower radiator hoses for any temperature difference.

What to Do If You Can't See the Lower Edge of the Mirror in Subject Two?

Align your shoulder with the start-stop control line, align the left rearview mirror with the start-stop control line, and maintain a 30 cm distance between the car body and the corner of the parking space in the rearview mirror. After entering the parking space, ensure the car body is parallel to the boundary line of the parking space. Align the lower edge of the left rearview mirror with the horizontal line of the parking space after entering. When exiting, the rear wheel should roll over the dashed line of the parking space.

What is the repair method for a non-functioning odometer?

Check if the odometer's wiring is normal; if it's broken or the teeth are worn out, replace it with a new wire. If it's neither broken nor worn out, then the odometer core is damaged, and replacing the core will suffice.

How to Align the Lines in Subject 2?

When the border of the outer rearview mirror aligns with the ground marking line, it indicates that the motor vehicle has successfully entered the reverse parking space, and you should stop immediately. Otherwise, the rear of the motor vehicle will extend beyond the garage, resulting in a failed test.
