Methods to remove rust from car brake discs are as follows: 1. If the rust is not severe, you can step on the brake a few times on a safe road section without affecting public traffic. 2. If the rust is severe, it is recommended to go to an auto repair shop and use sandpaper to polish it off. Methods to determine whether the brake disc needs to be replaced are as follows: 1. The brake pads and brake disc wear relatively. After replacing the brake pads 2 to 3 times, pay attention to checking the brake disc. 2. If you hear a rustling sound when braking, check whether the brake disc needs to be replaced. 3. If grooves or small pits appear on the brake disc and the measured depth reaches about 1.5mm, you need to go to a repair shop or 4S shop to check the brake disc.

What is the fuel tank capacity of the Jade?

The fuel tank capacity of the Jade is 50L, which is the officially announced data. Owners who have purchased the Jade can also check this information on the vehicle's configuration sheet. The recommended fuel grade for the Jade is 92 octane, with a fuel consumption of 6.3-7.1L per 100 kilometers. A full tank can cover a distance of 704 to 794km. During daily driving, it is necessary to always pay attention to the remaining fuel in the tank. This is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is designed to allow for fuel expansion when the temperature rises, preventing overflow from the tank's safety space. If the fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the marked fuel tank capacity.

What Causes Squeaking Brakes in Snowy Weather?

The reasons for squeaking car brakes in snowy weather include: rusted brake discs or pads, new brake pads, excessive wear of brake discs and pads, and assembly issues. Below are detailed explanations: 1. Rusted brake discs or pads: After parking for a long time, especially in humid climates or after rain, some rust or dirt may form on the brake discs or pads. This issue can usually be resolved by driving for a while or by applying butter or specialized lubricant at the connection between the brake pads and calipers. 2. New brake pads: New cars or those with newly replaced brake pads may produce similar noises. New brake pads and discs require a break-in period, and such noises during braking are normal. However, if the noise persists after some time, it indicates a problem. 3. Excessive wear of brake discs and pads: Both brake discs and pads are high-wear components that experience friction with every brake application. Over time, they naturally wear out, leading to unusual noises when excessively worn. Regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 kilometers, while brake discs last between 100,000-120,000 kilometers. 4. Assembly issues: If brake pads are installed incorrectly or are of the wrong model, they can also cause noise. Reinstalling the brake pads may help. Car owners should always have brake pads installed at professional auto repair shops, especially those who have had them replaced at roadside stalls, as this requires extra attention.
