What Causes Abnormal Noise When Braking in Reverse?

Abnormal noise when braking in reverse is caused by the use of inferior brake pads, foreign objects between the brake pads and brake discs, or improper installation of brake pads. Use of inferior brake pads: When brake pads rub against the brake discs, abnormal noise occurs. Therefore, it is essential to use high-quality brake pads when replacing them. The noise will gradually diminish as the brake pads and discs wear in, and braking performance will improve without requiring special treatment. However, avoid hard braking as much as possible, as it can accelerate wear and reduce the lifespan of the brake components. Foreign objects between the brake pads and brake discs: During normal driving, it is inevitable to encounter rough road conditions. Due to the unique design of disc brakes, sand or other debris may get lodged between the brake pads and discs, causing abnormal noise when braking. Try pressing the brakes firmly several times to help dislodge the particles. Improper installation of brake pads: Issues such as brake pads being too tightly fitted to the caliper or installed backward can also cause abnormal noise. Reinstalling the brake pads or applying specialized lubricant to the contact points between the brake pads and caliper can resolve the issue.

What is the function of a car inverter?

Car inverters can maximize the performance of solar batteries and provide system fault protection. The role of car inverters: A car inverter (power converter, Power Inverter) is a device that converts DC12V direct current into AC220V alternating current, which is the same as the mains supply, for use by general electrical appliances. It is a convenient vehicle power converter. It features automatic operation and shutdown functions, maximum power tracking control function, anti-islanding function, automatic voltage adjustment function, DC detection function, and DC grounding detection function. Precautions for using inverters: Strictly follow the instructions in the user manual when using the inverter; place it in a safe place to prevent electric shock; disconnect the input power when not in use; do not place the inverter in direct sunlight or near the outlet of a heater. The operating environment temperature of the inverter should not exceed 40 degrees Celsius; the inverter will generate heat during operation, so do not place items near or on top of it; the inverter is afraid of water, so do not expose it to rain or spill water on it.

What type of vehicle is the Yancheng SRT?

Yancheng SRT is a Super Virtual Rail Transit system. Features of SRT: It is an ultra-rail transit vehicle (approximately 36 meters long) that operates on virtual ground tracks, combining the advantages of rail transit and conventional buses. Integrating "low cost, medium capacity, intelligence, environmental friendliness, and convenience," it is a new type of rail transit system between trams and BRT. As a national new infrastructure project, it is also a next-generation 5G intelligent urban rail transit product, featuring pollution-free operation, no noise, high passenger capacity, low cost, and short construction cycles. Functions of SRT: SRT does not require laying steel rails; it operates along virtual tracks using the Beidou Navigation System and video guidance, ensuring good compatibility with bus systems and significantly reducing infrastructure costs. The investment cost is only 1/6 to 1/7 of that of trams. This bus system only supports electronic ticketing (E-Ticket) (card payment), with no onboard attendants. The SRT bus system has an automatic announcement function, automatically announcing station names and stops upon arrival without manual intervention.

What is the normal tire pressure in winter?

In winter, the normal tire pressure for cars is between 2.2 and 2.4 bar. Excessive tire pressure in winter reduces the friction between the car tires and the road surface, affecting driving safety. Slightly lowering the tire pressure by 0.1 bar below the standard can increase the tire's grip on the road. If the tire pressure is too low, it can increase the car's fuel consumption, cause damage to the tires, and easily lead to tire blowouts. The standard tire pressure for each car can be checked at the fuel filler location. The first row in the tire pressure chart indicates the standard tire pressure, which is generally 2.3 bar for most passenger cars. The tire pressure value refers to the cold tire pressure, measured after the car has been parked for at least 3 hours or if the tires have not been driven more than 2 kilometers. If tire pressure can only be measured when the tires are hot, subtract approximately 0.3 bar from the measured value. Strictly speaking, tire pressure refers to the air pressure inside the tires. In terms of car maintenance, the engine is the heart of the car, and damage to the engine can 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 car's performance and power.

How Many Kilometers Should a Major Car Maintenance Be Done?

Major car maintenance is typically recommended every 3 years or 60,000 kilometers, but the exact interval should be based on the vehicle's user manual. A major maintenance requires performing all the maintenance items listed in the manual. Major car maintenance includes servicing the engine, chassis, and body accessories. For engine maintenance, in addition to changing the engine oil and oil filter, it is necessary to inspect components such as the fuel system, oil pan, valves, oil seals, and spark plugs. If excessive wear or aging is found, these parts should be replaced. Chassis major maintenance mainly involves three major parts: the suspension, front and rear axles, and braking system. The hardware is inspected to ensure there is no wear or other damage, and then each component is realigned and reinforced. Additionally, shock absorber fluid, brake fluid, and lubricants are added or replaced. Major maintenance for body accessories includes checking parts such as tires, fenders, hood, dashboard, seat belts, seats, and foot pedals for looseness, aging or broken connectors, or misalignment. During major maintenance, car owners should pay attention to the condition of vehicle fluids, such as brake fluid, power steering fluid, transmission fluid, and shock absorber fluid. If these fluids were replaced not long before the major maintenance, it is important to communicate this with the service advisor.
