Why Does the Front Wheel Shake When Braking a Truck?

There are many reasons that may cause the front wheel to shake when braking a truck, mainly including excessive wear of the front wheel brake pads, excessive tire wear, or damage to the front shock absorbers. Trucks should regularly clean and inspect the brake pads; otherwise, it may affect driving safety. The specific details are as follows: 1. Excessive wear of front wheel brake pads: Normally, the thickness of car brake pads is about 10mm. If the brake pads are excessively worn and their surface becomes uneven, intense friction during braking can cause abnormal front wheel shaking. In this case, the wear level of the brake pads should be checked immediately and replaced. Generally, car brake pads should be replaced every 50,000 kilometers. 2. Excessive tire wear: If the car tires are out of round, bulging, or excessively worn, shaking may occur during braking, or severe bumpiness may be felt during normal driving. In such cases, timely repair or replacement of the tires is necessary to avoid safety hazards. 3. Damaged front shock absorbers: If the front shock absorbers are damaged, it may lead to issues such as shaking when braking, abnormal steering, or tire noise. In this situation, it is advisable to seek professional inspection at a repair shop or 4S store.

What is the Function of the Grille?

The function of the grille is to close when the engine temperature is relatively low, which accelerates the engine's warming speed and reduces exhaust emissions. Closing the grille when the engine temperature is low can also reduce wind resistance and improve fuel economy. Active grilles are automatically controlled and do not require manual operation by the driver. The active grille is located at the front of the car and consists of adjustable louvers that can control the opening angle. It maximizes the car's air intake efficiency and cooling efficiency through computer-controlled adjustments. In most vehicle models, the grille remains permanently open, which ensures that the engine receives maximum cooling power as soon as the car is started.

Can I switch to C2 after failing the C1 subject 2 test once?

C1 subject 2 test cannot be changed to C2 test after failing, and the test content cannot be changed arbitrarily during the test period; but after passing the test, the C1 test can be changed to C2 test. The C1 test subjects include four items: traffic regulations and related knowledge, field driving, road driving, and safe and civilized driving knowledge. C1 driver's license test passing standards: Traffic regulations and related knowledge (Subject 1) - written test, full score is 100, 90 or above is passing. Field driving (Subject 2) - on-site, actual vehicle. The minimum requirement is 80 points, below 80 is failing. Road driving (Subject 3) - highway or simulated site, actual vehicle. Full score is 100, must reach 90 or above to pass. Safe and civilized driving knowledge - written test, questions are mainly in the form of cases, pictures, animations, etc., question types include judgment questions, single-choice and multiple-choice questions, a total of 50 questions, full score is 100, 90 is passing. C1 application age: The minimum age limit for a C1 driver's license is 18 years old, and there is no upper age limit. However, applicants over 70 years old must pass tests on memory, judgment ability, reaction ability, etc.

What are the reasons for the sudden loss of power in the battery?

The reason for the sudden loss of power in the battery is: insufficient battery electrolyte, just add electrolyte. Car batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy. Batteries can be divided into ordinary batteries, dry-charged batteries, and maintenance-free batteries. Usually, the batteries people refer to are lead-acid batteries. The plates of ordinary batteries are made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main feature of dry-charged batteries is that the negative plate has a high power storage capacity, and in a completely dry state, it can preserve the obtained power for two years. Due to the structural advantages of maintenance-free batteries, the consumption of electrolyte is very small, and it is basically unnecessary to replenish distilled water during their service life.

Where is the air intake for the car's internal circulation located?

The air intake for the car's internal circulation is located on the passenger side, below the glove box on the dashboard. The method to use the internal circulation is: Press the internal circulation button inside the car. In the internal circulation state, the air exchange channel between the inside and outside of the car is closed. When the fan is off, the air inside the car does not circulate; when the fan is on, the air drawn in comes from inside the car, forming an internal air circulation. Car air conditioning refers to the air conditioning device installed in the car, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety.

Does Minor Cylinder Scoring Require an Overhaul?

Minor cylinder scoring does require an overhaul. The main cause of cylinder scoring in automobiles is insufficient engine oil, which leads to excessively high temperatures during continuous engine operation. This can cause certain damage to bearings and pistons, and the extreme heat may also result in cylinder block cracking, severely affecting vehicle performance. Automobile cylinder scoring refers to the 'welding' abrasion between the piston, piston rings, and cylinder liner surfaces due to high temperatures. Specifically, it occurs when the oil film between the piston and cylinder liner breaks down, causing dry friction. The intense frictional heat leads to microscopic metal melting and adhesion, tearing nearby metal particles. According to gas sealing requirements, the clearance between piston rings and cylinder liners should be as small as possible, creating extremely unfavorable lubrication conditions.
