What to Do If Brake Pads Are Too Hard and Make Abnormal Noises?

What does the tire specification 245/50r20 mean?

245/50r20 is the tire size specification, indicating that the tire's section width is 245 millimeters, the aspect ratio is 50, 'r' stands for radial tire, and 20 means it can be mounted on a 20-inch rim. The tire maintenance methods are as follows: 1. Inspection: Pay special attention to the condition of the tires, checking for any debris or foreign objects lodged in them. If found, remove them promptly. If not removed in time, some may fall off during driving, while others may gradually 'erode' the tire, penetrating deeper over time. When this reaches a certain point, they can puncture the tire, leading to blowouts or leaks, which can be dangerous. 2. Timely replacement: During inspection, if the tire valve is made of rubber and turns dark red, it indicates that the valve has aged and can no longer ensure good airtightness. It is best to replace it. 3. Check wheel balance: During driving, the tires may experience impacts, high-speed driving, sharp turns, emergency braking, or crossing obstacles, which can cause the tires to lose balance. This can result in vehicle pulling, bumpiness, or uneven tire wear (commonly known as 'tire cupping'), affecting driving safety. 4. Check tire pressure: Monitoring tire pressure is the most important aspect of daily tire maintenance. It is good practice to develop a habit of checking tire pressure regularly (preferably once a week) to eliminate potential hazards early. Tire pressure should be checked when the tires are cold, as driving heats up the tires, causing the pressure to read higher than the actual value. If you reduce the pressure of a hot tire, it will be insufficient once cooled.

What happens if spark plugs are not replaced for a long time?

The effects of not replacing spark plugs for a long time include: 1. Increased fuel consumption and loss of vehicle power; 2. Difficulty in starting the car, with severe shaking occurring during startup; 3. Damage to the car's catalytic converter, leading to excessive exhaust emissions. The functions of spark plugs are: 1. To introduce the high voltage electricity generated by the ignition coil into the engine cylinder; 2. To generate sparks between the spark plug electrode gaps to ignite the air-fuel mixture, ensuring normal engine operation. The types of spark plugs include: 1. Standard spark plugs; 2. Insulator projection spark plugs; 3. Electrode spark plugs; 4. Seat-type spark plugs; 5. Pole-type spark plugs; 6. Surface gap spark plugs.

How Often Should Car Door Seals Be Replaced?

Car door seals should be replaced every 3 to 4 years. Seals are commonly found on car doors, windshields, and power windows, serving to prevent water from entering the vehicle and enhancing sound insulation. These seals fill gaps between body components, providing functions such as vibration reduction, waterproofing, dustproofing, sound insulation, and decoration. Key considerations for replacing seals include: 1. Before replacement, carefully compare the existing seals on the vehicle to select the correct type, as different car models use different seal designs; 2. After selecting the appropriate seal, remove the old seal and thoroughly clean the area where the new seal will be applied before installation.

How many kilometers for the first maintenance of Honda Civic?

Honda Civic's first maintenance is recommended at 3,000 to 5,000 kilometers. The maintenance items include: 1. Check whether the tire pressure is normal and whether the tires have uneven wear, bulges, or damage; 2. Inspect the car chassis, brake pads, brake discs, connecting rods, ball joints, and CV joints for scratches; 3. Replace engine oil, oil filter, and clean the air filter; 4. Check whether the generator belt and wiper blades are damaged; 5. Check whether the levels of various fluids are normal; 6. Inspect all switches and lights to ensure they are working properly. Taking the 2021 Honda Civic as an example, it is a compact car with a body size of 4517mm in length, 1799mm in width, and 1434mm in height, a wheelbase of 2700mm, a minimum ground clearance of 104mm, and a curb weight of 1343kg.

What models are compatible with 70/90-10 tires?

Tires should be purchased and installed with the same model as the original vehicle tires. Inconsistent models will affect the safety and stability of the vehicle. The following is relevant information about tires: 1. Wear: Tires have wear indicators. There are triangle marks on the side of the tire. When worn to the position indicated by the triangle mark, it is recommended to replace the tire. There are also raised marks inside the tire tread grooves. When worn to the point where the raised marks are level with the tire surface, the tire should be replaced. Simple punctures can be repaired without replacement. Bulges must be replaced. 2. Aging: Rubber oxidizes in the air, and oxidized rubber hardens, reducing grip. Therefore, even if a set of tires is left unused, their lifespan will decrease. It is not recommended to use tires for more than 5 years from the production date. The production date is indicated on the side of the tire.
