What are the methods for car tire repair?

There are several methods for car tire repair: 1. Patch repair (internal repair): This is the most common method. It involves separating the tire from the rim, then sanding the damaged area of the tire. To ensure a strong bond, the debris from sanding must be cleaned off, and tire repair glue is applied to the damaged area and its surroundings. A repair patch is then firmly pressed onto the damaged area, followed by an additional layer of glue. 2. Mushroom plug repair (internal repair): Mushroom plug repair is currently the most advanced and convenient tire repair method. Compared to other repair methods, mushroom plug repair is more reliable.

What Causes the Vehicle to Pull to One Side When Braking?

The reason for the vehicle pulling to one side when braking is: uneven braking force between the left and right sides. When this occurs, it is necessary to visit a professional institution for adjustment. The braking system of a car is extremely important as it directly affects the vehicle's driving safety and stability. The braking system mainly consists of a vacuum booster pump, master brake cylinder, brake caliper, brake pads, and brake discs. Below are the maintenance methods for the braking system: 1. Use a professional brake disc cleaner. Before use, shake the liquid in the can thoroughly, then spray it directly onto the area to be cleaned until dust and oil stains are completely removed. Wipe clean with a clean towel, leaving no dust or residue. 2. Use a professional brake caliper guide pin lubricant. Wear a single-finger glove and apply the product evenly on the surface of the brake caliper guide pin and inside the guide pin groove. Do not mix with other mineral lubricating oils. 3. Use a professional high-temperature resistant brake pad protector. Wear a single-finger glove and apply the product evenly on the back of the brake pads and inside the sliding grooves at both ends of the brake pads. 4. Use a professional high-temperature anti-seize lubricant. Wear a single-finger glove and apply the product evenly on each tire bolt and the metal contact surface between the wheel rim and the hub.

What Items Should Be Added to a New Car?

New cars require the addition of essential items such as a dash cam, parking sensors, fire extinguisher, odor-absorbing charcoal bags, and child safety seats. Depending on personal needs, you may also consider installing seat covers, paint sealant, or mud flaps. If it's a learner's vehicle, ensure to display a "Learner" sticker. Below are some important precautions for driving a new car: 1. Avoid maintaining the same speed and gear for extended periods. Instead, use gears appropriately to allow even wear across all gears. 2. Avoid sudden braking, as it strains the engine and affects the braking system. Also, refrain from long-distance driving. 3. If time permits, warm up the engine before driving to ensure proper lubrication. Wait until the engine idle stabilizes and the coolant temperature reaches normal levels before setting off. 4. Initially, avoid overloading the car—keep the load below 80% of the maximum capacity to reduce strain on the engine.

How to Check for Car Battery Leakage?

Check for car battery leakage by following these steps: 1. Turn off the car's ignition switch to put the vehicle in a dormant state; 2. Locate the tightening nut on the battery's negative terminal, loosen it with a wrench, then gently pry open the tightening block with a flathead screwdriver and disconnect the negative terminal; 3. Set the multimeter to the DC 10A or 20A range, connect the red probe to the car's grounding wire and the black probe to the battery's negative terminal post; 4. Observe the multimeter reading. Solutions for car battery leakage include: 1. Remove the positive cable from the battery; 2. Wrap the battery in a plastic bag; 3. Check the ignition status once; 4. Inspect the electrolyte level; 5. Measure the electrolyte density.

What is the difference between electronic parking brake and auto hold?

Electronic parking brake and auto hold mainly have the following differences: 1. Different usage methods: The electronic parking brake needs to be manually activated; while the auto hold does not require manually pressing a button, simplifying operation by avoiding the use of handbrake or electronic parking brake. 2. Different working principles: The electronic parking brake is essentially a handbrake, changing from pulling a mechanical handbrake lever to pressing a button; while the auto hold is an extended function of the electronic parking brake. 3. Different usage scenarios: The electronic parking brake is used for daily parking; while the auto hold is more suitable for stop-and-go traffic conditions in urban areas.

Why does it feel like scraping the undercarriage when braking?

The main reason for the sensation of scraping the undercarriage when braking is excessive wear in the braking system. Here is a detailed explanation of the causes: 1. The most worn parts in the braking system are the brake pads and brake discs. When these are excessively worn, braking can cause a scraping sensation. 2. The friction material on the brake pads may be completely worn away, exposing the underlying metal. During braking, the metal rubbing against the brake disc produces a metallic scraping sound similar to that of scraping the undercarriage. 3. If there are pits or unevenness on the brake disc, severe braking noise can also occur when the vehicle is braking. In such cases, the brake disc may need to be replaced or resurfaced.
