Parking brake faults are as follows: 1. Parking brake failure: The main causes of failure are excessive clearance between the friction plate and brake drum, oil contamination on the friction plate or brake drum, or severe wear of the friction plate. Immediate repair is required. 2. Abnormal noise: Manually swing the parking brake to check for loose fixing screws, deformed operating lever, loose fixed pins, or damaged operating lever spring. Timely repair and adjustment are necessary. 3. Parking brake lever cannot be fixed: At the unfixed braking position, inspect the lever head. Grip and release the lever handle, perform up and down movement tests to check if the lever is bent, stuck, or if the spring is broken.

How to Operate a Car Atomizing Disinfector?

The specific method for using a car atomizing disinfector is as follows: first, place the atomizing disinfector in the central position inside the car that needs to be disinfected, or in another location conducive to ozone diffusion. Then, set the disinfection time, turn on the car's internal circulation, and switch on the power supply to set the microcomputer controller to automatic mode. Open all doors and ventilate for a few minutes. Below is an introduction to the car atomizing disinfector: 1. Principle: The device atomizes the antibacterial agent into ultra-fine particles of hundreds of millions of nanometers in size. These ultra-micro nano antibacterial particles can more effectively kill bacteria and molds in the air and on surfaces, leaving them nowhere to hide. 2. Function: When the fan or air conditioning is operating simultaneously, placing the atomizing disinfector near these facilities helps in better diffusion of ozone, achieving a more effective disinfection result.

How Many Chances Are Left for the Driving Test Subject 3?

There are 5 test opportunities for the driving license Subject 3. Subject 3, also known as the road test, is part of the motor vehicle driver's license assessment and is the abbreviation for the road driving skills and safe civilized driving knowledge test in the motor vehicle driver's examination. Relevant information: 1. The content of Subject 3 generally includes: vehicle preparation, light simulation test, starting, straight-line driving, gear shifting operation, lane changing, pulling over, passing through intersections straight, left turns at intersections, right turns at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, turning around, and night driving. 2. Notes for the Subject 3 test: (1) If the candidate's fingerprint verification fails, please exit the vehicle to re-collect the fingerprint before queuing again for the test. (2) During the test, if the candidate's score is below the passing score, the system will automatically prompt the candidate to pull over. After completing the pulling over action, the system will prompt for the next test. (3) After the candidate completes all required test items as required and drives a distance of more than 3 kilometers, the system will automatically prompt to pull over. After hearing the voice prompt to pull over, the candidate should choose a clear curb (or solid road edge line) on the test route and complete the pulling over action after confirming safety. After pulling over, the system will announce the test results via voice. (4) When walking around the vehicle to observe the vehicle's appearance and surrounding environment, to ensure the accuracy of radar signal detection, please keep the distance between the person and the vehicle within 1 meter.

When can I take the test after my driver's license is suspended for six months?

The penalty notice will indicate the collection date and location. The suspension period for the motor vehicle driver's license is calculated from the effective date of the penalty decision; if the driver's license was impounded before the penalty decision takes effect, each day of impoundment will be deducted from the suspension period. Here is the relevant information: 1. Retaking the test: Within 15 days after receiving the penalty notice, you must attend a full-score learning test. After the suspension period ends, bring your ID card and the "Motor Vehicle Driver's Illegal Full-Score Test Information Feedback Notice" to the traffic management department of the public security authority that impounded your driver's license to retrieve it. Each driver's license has 12 points in a scoring cycle. When you commit a traffic violation, points will be deducted. If all 12 points are deducted, your driver's license will be suspended. 2. Suspension period: Generally, the suspension period for a driver's license is six months. Additionally, when suspending the license, the traffic police will issue a suspension certificate, which you will need to present to retrieve your license from the traffic management office later.

Where is the Air Filter of GAC Trumpchi GS5 Located?

The air filter of GAC Trumpchi GS5 is located inside the glove compartment on the passenger side. Remove the glove compartment to access the air filter. The manufacturer recommends replacing the air filter every 10,000 kilometers or once a year, and it can be cleaned every 5,000 kilometers. Here is some relevant information about car air filters: 1. Introduction: The car air filter is a specialized filter designed for purifying the air inside the vehicle cabin. It uses activated carbon composite filter cloth, which combines highly efficient adsorption material (activated carbon) with long-fiber non-woven fabric, resulting in a compact structure. 2. Function: It effectively filters out smoke odors, pollen, dust, harmful gases, and various other odors. The filter also efficiently traps and adsorbs particulate impurities, providing oil filtration and air purification capabilities.

Is Car Window Film Applied on the Inside or Outside?

Car window film should be applied on the inside of the car glass. If applied on the outside, it is easily eroded by wind and frost, leading to faster aging and a shorter lifespan. The functions of the film are as follows: 1. UV Protection: It mainly blocks ultraviolet rays, reduces heat, and prevents injuries caused by sudden glass shattering. Additionally, the one-way transparency feature of the film helps protect personal privacy. 2. Reduced Air Conditioning Consumption: The film compensates for the loss of air conditioning cooling capacity, instantly lowering the interior temperature and achieving a certain degree of fuel savings. 3. Enhanced Aesthetics: According to personal preference, the film can personalize and beautify the car. 4. Anti-Glare: It reduces accidents caused by glare factors.

How to Determine Engine Water Temperature Levels?

Methods to determine engine water temperature are as follows: 1. Temperature Gauge: Check the temperature gauge. 2. Steam: Observe if there is steam escaping. 3. Warning Light: Monitor the water temperature warning light. Specific reasons causing abnormal water temperature include: 1. Insufficient Coolant: Before driving in summer, it's essential to check coolant levels. If you're on a highway or in a remote area and run low on coolant without access to purchase more, you can temporarily use water as a substitute. However, when adding water, be extremely cautious not to open the radiator cap immediately after stopping the car. The internal temperature is very high, and pressure is significant; opening the cap immediately can cause hot steam to burst out, potentially scalding your face. The correct approach is to wait until the radiator temperature slightly decreases before slowly opening the cap to add water. 2. Dirty Radiator: Radiators have many cooling fins with small holes. Dust, mud, lint, and other impurities can easily adhere to these fins, clogging the small holes and reducing the radiator's cooling efficiency. This situation may not have a significant impact in winter, as the surrounding environmental temperature is low, and direct cooling is usually sufficient. However, in summer, when the temperature difference between the radiator and the external environment decreases, cooling slows down, making it easy for the water temperature to become too high.
