The reasons why the Peugeot 308's brakes feel stiff and hard to press, making it difficult to stop the car, are as follows: Pressing the brakes before turning off the engine: The vehicle's braking system operates at maximum efficiency only when the engine is running. The brake booster pump is the key component enabling vehicle braking. When the engine is off, typically pressing the brake pedal 3 times will deplete its remaining vacuum power. You need to restart the engine and try pressing the brake pedal firmly again. Brake booster pump air leakage or malfunction: If you didn't press the brake pedal after turning off the engine, or if you find the brake pedal extremely hard to press while driving, it may be caused by air leakage or blockage in the brake booster pump's vacuum tube. Inspection and repair are required.

Is it mandatory to purchase insurance from a 4S store for a financed car?

It is not mandatory to purchase insurance from a 4S store for a financed car; you can make a choice based on your own situation. Generally, financing a car can be divided into two scenarios: 1. Using a car consumer finance company that cooperates with the 4S store to finance the car; 2. Obtaining a loan from another bank or financial institution and then purchasing the car from the 4S store. Below are some considerations when purchasing a new car: 1. Inspect the paint: Check the body surface for scratches or dents. Verify whether the paint thickness is uniform. Look for any signs of touch-ups in the engine compartment or the edges under the car. 2. Check the gaps: Inspect whether the gaps around the front hood, doors, and their frames are uniform, and whether the gaps on both sides of the front hood are symmetrical.

What are the methods for troubleshooting automatic transmission failures?

Automatic transmission troubleshooting methods are: 1. Computer diagnostics, replacing damaged electronic components; 2. Repairing damaged mechanical components; 3. Inspecting the engine and ABS, repairing damaged parts; 4. Analyzing each possible cause of the phenomenon, such as high engine coolant temperature, transmission clutch slippage, insufficient cooling, vehicle overheating, or clogged radiator grille. Transmission maintenance methods are: 1. According to research, over 90% of transmission failures are caused by excessive temperature. The transmission must operate within a working temperature range of 85 to 95 degrees. Regularly replace antifreeze and engine oil; 2. Periodically check transmission fluid levels, ensuring it is not too low, as this can increase mechanical resistance during operation.

What does the red exclamation mark inside a triangle in a car mean?

The red exclamation mark inside a triangle in a car is a general fault indicator light. Possible causes for its illumination include overheating of the dry dual-clutch transmission clutch, intervention or malfunction of the fuel cut-off system, parking sensor failure, external light malfunction, engine oil pressure sensor failure, or traction control system warning/failure. In addition to this general fault light, other warning lights featuring an exclamation mark include the brake system warning light and the tire pressure monitoring indicator light. When the vehicle's electrical system is activated, the indicator lights on the dashboard will illuminate as the car enters self-check mode. These lights should turn off after the self-check is completed. If they remain lit, it indicates a vehicle malfunction that requires prompt repair.
