What Causes the Car Body to Shake When Braking?

The reason the car body shakes when braking is due to uneven surfaces on the brake discs. When this occurs, the brake discs need to be replaced. A car's braking system consists of the master brake cylinder, vacuum booster, brake caliper, brake pads, and brake discs. When the brake pedal is pressed, the vacuum booster provides assistance, making it easier for the driver to depress the brake pedal. Braking refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force.

Will it rust after being repaired with a touch-up pen?

It will not rust after being repaired with a touch-up pen. A more effective method to deal with rust on the car paint surface is to first sand it clean with sandpaper, then use fine sandpaper with 1000 grit or higher to sand it again. After continuous sanding, repaint the area. If there is no rust on the paint surface and the surface oxidation is covered by the touch-up pen, as long as the coverage is complete and the galvanized sheet inside does not come into contact with air, it will not rust. A touch-up pen is a tool for repairing car scratches. By selecting the appropriate model that matches the original car paint color, you can perform the repair yourself. After applying the touch-up pen to small scratches or areas where the paint has peeled off, it conceals and fills in the scratches. The composition of the touch-up pen is generally the same as the original car paint.

Can I still drive with a tire pressure of 1.7?

Tire pressure of 1.7 is not suitable for driving, as the normal tire pressure should be between 2.3 and 2.5. Low tire pressure increases the movement of the tire, and the high friction causes the tire temperature to rise, making the tire softer and reducing its strength. If you drive at high speeds for a long time, it may lead to a tire blowout. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and engine damage will lead to the end of the car's life. Tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car.

What Causes the Buzzing Sound and Resonance Sensation During Car Idling?

The reasons for a car producing a buzzing sound and resonance sensation during idling are: 1. Tensioner pulley wear: Due to prolonged pressure and high-speed rotation, the bearings in the tensioner pulley can easily wear out, causing noise and resonance; 2. Exhaust pipe deformation: A deformed exhaust pipe increases exhaust resistance, leading to a buzzing sound and resonance sensation; 3. Wheel hub bearing wear: Wheel hub bearings are installed in the suspension's "knuckle" and constantly bear the vehicle's weight and impact during daily driving, making the bearing balls inside the wheel hub bearings prone to wear, resulting in a buzzing sound and resonance sensation. Idling is an operational condition of a car, where the engine runs in neutral gear. The engine speed during idling is called the idle speed, which can be adjusted by modifying the throttle opening size, among other methods.

What Causes the Gearbox Noise in the Tayron?

The gearbox noise in the Tayron is due to its use of a dual-clutch transmission. It is normal for a dual-clutch transmission to produce metallic clunking sounds under certain conditions. However, if the noise occurs frequently, it is recommended to have it inspected at a repair shop. A dual-clutch transmission is a semi-automatic transmission with two sets of clutches. Its structure is very similar to that of a manual transmission, featuring two sets of clutches responsible for shifting between even and odd gears, significantly improving gear-shifting speed. The Tayron is a mid-size SUV under the Volkswagen brand. The vehicle measures 4589mm in length, 1860mm in width, and 1660mm in height, with a wheelbase of 2731mm. It is equipped with either a CUG 2.0T high-power engine or a DBF 2.0T low-power engine, delivering maximum power outputs of 220 horsepower and 186 horsepower, respectively.

How to Remove Small Tree Sap Dots from the Car Body?

Methods to remove small tree sap dots from the car body are: 1. Soak and wipe with alcohol solvent: Ethanol is very effective in dissolving and removing tree sap. Simply dip a cloth in alcohol and wipe; 2. Wipe with soapy water solution: Use ordinary soapy water to clean the tree sap, which is simple and easy to operate; 3. Wipe with car cleaning clay: Car cleaning clay is a high-density gel-like substance with strong cleaning power and certain polishing effects; 4. Soak and wipe with warm water: Pour warm water onto a cleaning cloth, cover the sap-stained area on the car body, and after a while, the sap will melt, making it easier to wipe off.
