The reasons for the entire car shaking when braking are: 1. Tire deformation; 2. Incorrect tire dynamic balance; 3. Vehicle transmission system failure; 4. Worn or loose ball joints or detached rubber sleeves at connection points; 5. Twisted or deformed drive shaft; 6. Uneven brake discs; 7. Overly loose or tight power steering belt. Braking, also known as stopping, refers to the action of halting or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The methods to address the entire car shaking when braking are: 1. Check whether the ignition coil has leakage or internal short circuit; 2. Check whether the ignition coil wiring plug is loose or has poor contact; 3. Check whether there is corrosion at both ends of the battery; 4. Check whether the vehicle body grounding is good.

I've been driving my car for over a decade and have encountered brake shudder several times. Usually, this is caused by warped brake rotors or uneven surfaces. When you press the brakes, the brake pads rub against the uneven rotors, making the car shake like an earthquake. Another common reason is uneven wear of brake pads or improper installation, which creates unstable contact points. If there's an issue with the suspension system, such as worn-out shock absorbers or insufficient bounce, it can also cause the entire car to shake. I've also considered out-of-round wheels or uneven tire wear as potential causes. The last time my car shook badly, driving felt like being on a boat, so I immediately went to a nearby repair shop. The technician quickly identified severe scoring on the brake rotors, and replacing them fixed the issue. Safety first—I recommend not pushing through it but stopping immediately and seeking professional inspection. Regular maintenance of the braking system can help avoid such problems. Never ignore these minor issues, as they can easily lead to major accidents.

What should be noted when keeping the original license plate after changing cars?

If you want to keep your original license plate number, you must first dispose of your old car before attaching the original license plate number to the new car. According to the "Motor Vehicle Registration Regulations," the original owner must meet the following conditions to apply for the use of the original license plate number: 1. First, the owner must have owned the original motor vehicle for more than three years. If the original owner used the vehicle for less than three years, they are not eligible to apply for retaining the original license plate. 2. Second, the application must be submitted within six months after completing the transfer or cancellation registration. In other words, after transferring the vehicle to a new owner or scrapping it, you only have six months to purchase a new car and apply. 3. Lastly, any traffic violations or accidents involving the original motor vehicle must be resolved. If there were any traffic violations or unpaid fines related to the original vehicle, all fines must be paid, and no unresolved accidents should remain before applying to retain the original license plate number. 4. Additionally, the owner must purchase a new car to retain the original license plate number. If the new vehicle purchased by the original owner is a used car, retaining the original license plate number is not permitted.

What maintenance does the Sagitar need at 60,000 kilometers?

Volkswagen Sagitar's 60,000-kilometer maintenance items include: changing the engine oil, oil filter, air filter, cabin air filter, transmission fluid, and spark plugs. Below are the detailed explanations: 1. The 60,000-kilometer maintenance for the Volkswagen Sagitar is a major service, as the vehicle has accumulated significant mileage by this point, leading to considerable wear and tear, necessitating the replacement of many parts. 2. In addition to changing the engine oil and oil filter, the air filter and fuel filter should also be replaced. 3. During operation, the engine draws in a large amount of air. If the air is not filtered, the dust in it can accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can also cause severe "cylinder scoring." 4. The fuel filter's role is to provide clean fuel to the engine by filtering out moisture and impurities from the gasoline. This optimizes engine performance and provides the best protection for the engine. 5. Typically, during vehicle maintenance, the service personnel will conduct additional inspections based on the specific condition of the car and may include other maintenance items, such as inspection and cleaning of the engine-related systems, wheel alignment checks, inspection of various fastening components, etc.

Should Honda Motorcycles Use 10W30 or 10W40?

Honda motorcycles should use 10W40. Here is additional information: 1. 10W30 vs. 10W40: Both 10W30 and 10W40 are all-season oils, but 10W30 offers slightly better performance than 10W40. For oil viscosity grades, the "W" stands for "Winter," and the number before the W indicates the oil's low-temperature fluidity. The smaller the number, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. The number after the W represents the oil's viscosity at 100°C. The larger the number, the higher the viscosity, and the better the high-temperature protection. 2. Differences: 10W30 and 10W40 have the same low-temperature fluidity, maintaining normal viscosity at temperatures above -25°C, ensuring the vehicle can start normally and the engine can operate smoothly. However, their high-temperature viscosities differ: 10W30 has lower high-temperature viscosity, better fluidity, and can reduce fuel consumption while allowing the engine to dissipate heat faster. However, after use, the engine noise may be relatively louder. 10W40 has higher high-temperature viscosity, is thicker, and can handle greater engine loads after use, resulting in quieter operation, less vibration, and greater stability. However, its fluidity is poorer, creating more resistance for internal engine components and consuming more fuel.

What are the causes of car deviation?

Here are the reasons that affect car deviation: 1. Different tread patterns on both sides of tires: It is best to use the same type of tires for the entire vehicle. The two tires on the front axle and rear axle must be the same, and the tread depth must also be the same. Tires exceeding the wear limit must be replaced. 2. Unequal tire pressure on both sides: Unequal tire pressure will cause the tires to become different in size, inevitably leading to deviation when rolling. 3. Deformation of front shock absorber springs and inconsistent cushioning on both sides: The quality of the shock absorber springs can be judged by pressing or comparing after disassembly. 4. Failure of front shock absorbers: After the front shock absorbers fail, the two suspensions will be uneven during vehicle driving, resulting in uneven force and causing deviation. 5. Excessive wear of vehicle chassis components and abnormal gaps: The ball joints of the steering rods, rubber bushings of the support arms, and rubber bushings of the stabilizer bars are common parts where gaps are prone to be too large. The vehicle should be carefully inspected. 6. Poor return or separation of a certain tire's brake can also cause directional deviation. 7. Overall deformation of the vehicle frame: Excessive difference in the wheelbase on both sides beyond the maximum allowable range can be measured with a tape measure. If it exceeds the range, it must be corrected with a calibration bench. 8. Not paying attention to the tread direction when installing tires: Check whether the tires were installed without noticing the tread direction.
