The reasons for abnormal noise when braking are: 1. Normal activation of ABS; 2. Newly replaced brake pads; 3. Excessive wear of brake discs and brake pads; 4. Sand or mud entering the brake pads. The function of brakes is to reduce speed or bring the vehicle to a stop. Their working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and brake drums, as well as between the tires and the ground, thereby slowing down or stopping the car. The reasons for brake failure are: 1. Impurities or poor sealing in the brake master cylinder; 2. Failure of the vacuum booster pump; 3. Contaminated brake fluid; 4. Leakage in the brake master cylinder or wheel cylinder; 5. Air leakage in the air reservoir or pipeline connections; 6. Severe overloading; 7. Carbonization of the brake drum; 8. Insufficient brake fluid in the brake master cylinder; 9. Wear of the brake master cylinder piston.

How many points are deducted for making a left turn in a dedicated U-turn lane?

As long as the left-turn lane has a U-turn marking, making a U-turn is not considered a violation. If there is a dedicated U-turn lane, making a U-turn in the left-turn lane is a violation, and failing to follow the directional markings will result in a deduction of 2 points. Below are the situations where a U-turn does not require waiting for a traffic light: 1. Signage indication: If there is a sign before the traffic light intersection indicating that the U-turn is not controlled by the traffic light, you can make a U-turn directly without waiting for the green light. 2. U-turn dotted line: If there is a U-turn dotted line before the traffic light intersection, and the dotted line does not exceed the stop line, you can make a U-turn directly without being controlled by the traffic light. 3. Dedicated U-turn channel: If there is a dedicated U-turn channel before the stop line, such as in the median or behind barriers, this situation is not controlled by the traffic light.
