Why Do Brake Pads Always Make Noise?

Here are the reasons why brake pads make noise: 1. Using low-quality or overly hard brake pads. When braking, the friction between the brake pads and the brake disc can produce a squeaking sound. Always use high-quality brake pads when replacing them. 2. Sand or foreign objects between the brake pads and the brake disc. When driving through complex road conditions, sand or foreign objects may get between the brake pads and the brake disc, causing noise. 3. Severe wear on the brake disc. If the brake disc is excessively worn, it will produce a squeaking sound when braking. 4. Brake pad warning. Some low-end vehicles use warning indicators. If the wear on the brake pads reaches the warning line, it will emit a squeaking alarm sound.

Does coasting in neutral damage a manual transmission car?

Coasting in neutral does damage a manual transmission car. Definition of coasting in neutral: Coasting in neutral refers to the operation method where, while the vehicle is in motion, the driver shifts the gear lever to the neutral position, disengaging the clutch between the engine and the drive wheels, allowing the vehicle to move by inertia. Hazards of coasting in neutral with a manual transmission: Damage to the braking system: Prolonged coasting in neutral, such as when descending a hill, causes the vehicle speed to increase due to gravitational assistance, necessitating frequent brake application. Continuous braking raises the temperature of the braking system, eventually causing the brake fluid to vaporize. Damage to the braking mechanism: Similar to "engine braking" when descending hills, the vehicle's drivetrain utilizes internal resistance (through friction plates coupling the engine and transmission) to control speed, which effectively acts as an internal brake at high speeds. Safety hazards: When two vehicles are close together and the leading vehicle stops suddenly in an emergency, if the following vehicle is coasting in neutral, it must rely entirely on its wheel braking system, significantly increasing the likelihood of a rear-end collision.

How many exam attempts are allowed for Subject 2 and Subject 3 combined?

For Subject 2 and Subject 3, each appointment allows one exam attempt. If the exam is not passed, an immediate retake is permitted. If the candidate does not take the retake or fails the retake, the exam session ends, and the applicant must reschedule the exam after ten days. Within the validity period of the driving skill test permit, the number of exam appointments for Subject 2 and Subject 3 (road driving skills) must not exceed five. If the fifth attempt is still unsuccessful, the passing scores of other previously passed subjects will be invalidated. Subject 2 is scored out of 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, or deducting 5 points. The exam is considered passed under the following conditions: ① For large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. Subject 3 is scored out of 100 points, with a passing score of 90. The exam generally includes: vehicle preparation, light simulation test, starting, straight-line driving, gear shifting, lane changing, pulling over, proceeding straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crosswalks, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and night driving.

What is the normal intake air temperature for a sedan?

Sedan intake air temperature is normally between 10 to 50 degrees Celsius. The intake air temperature sensor is a negative temperature coefficient thermistor. When the temperature rises, the resistance value decreases; when the temperature drops, the resistance value increases. The change in resistance within the circuit causes a change in voltage, thereby generating different voltage signals to complete the automatic operation of the control system. The intake air temperature sensor consists of a 5V voltage THA supplied by the engine ECU and an E2 ground wire connected to the engine's internal ground. It is installed on the intake pipe or inside the air flow meter, and its function is to detect the engine's intake air temperature and convert it into a voltage signal input to the ECU as a signal for fuel injection correction.
