Difficulty in pressing the brake pedal may be due to a leak or malfunction in the car's brake booster pump. 1. Possible causes: Regular maintenance of the brake system is essential during normal vehicle use. Common issues include excessive impurities in the brake master cylinder, poor sealing, leaks in the brake master or wheel cylinders, failure of the vacuum booster pump, or overloading. It is recommended to inspect the brake master cylinder and its bleeding condition; check if the brake fluid is sufficient; examine the brake fluid lines for leaks; and inspect the brake wheel cylinders, brake pads, and related components. 2. Solutions: If the brake fluid contains too much moisture, it can evaporate and vaporize under high temperatures (such as during summer when exposed to intense heat, the brake temperature rises with frequent use), forming vapor locks in the brake lines and causing sluggish braking. In this case, the brake fluid needs to be replaced.

How to Check the Water Level in a Car?

Methods for checking the water level in a car: Open the front engine hood to inspect it. If the dashboard indicates the engine temperature is too high, it is usually caused by insufficient water in the radiator. The car's radiator has MAX and MIN warning lines. When the level is below MIN, the car can still be driven, but it serves as a reminder for the owner to promptly add antifreeze. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. Many people believe antifreeze is only used in winter, but in fact, it should be used year-round.

What does the 'off' sign on a car mean?

The 'off' sign on a car means 'turn off'.

Where is the front reinforcement bar located in a car?

There is no fixed position for the front reinforcement bar on the right side of the car; it mainly depends on the structural design of the vehicle. It could be on the door or elsewhere. Reinforcement bars are generally not placed on the body frame because the passenger compartment section of the body frame is made of high-strength materials. Below is a related introduction to the car frame: Body Composition: The body is divided into the body frame and body panels. The panels include the front and rear bumpers, hood, doors, front fenders, and trunk lid. Body Frame: After removing the panels, what remains is the body frame. Since the roof and rear fenders are welded to the body frame, they are considered part of the body frame and not the panels.
