When to replace brake disc

First, the brake disc generally needs to be replaced when the front brake disc is about 80000 km. The mileage varies according to personal driving habits, but one value is that the fixed brake disc groove friction depth is greater than 3mm and must be replaced. If you touch the obvious deep groove with your eyes or hands, you must replace it. The mileage of the rear disc is relatively long, The standard for brake pad replacement is also 3mm.

Second, when the brake pad needs to be replaced, an obvious brake disc alarm sound will be heard! Brake oil: 40000 km in 2 years! The environment is poor, the mileage is shorter, and the automatic transmission oil must be replaced for 60000-80000 kilometers. Believe me, it's right, because with the increase of time, the mileage is worn, the oil sludge in it increases (iron foam), the lubrication and cooling effect decreases, the acceleration is weak, and the gear shift is slow. At a certain mileage, go to a professional transmission to repair and replace the oil.

Third, the same pit as 5000 km oil change. If the brake pad is too thin, there will be metal friction sound or the distance from the brake disc from the side. There is a limit mark on the outer circle of the brake disc. If you can't grind it, you can polish it on a professional machine if the disc is deformed. The effect is the same. It's still a durable part of the original car.

Fourth, can the car drive when the brake disc needs to be replaced? I didn't even replace the brake pads after 120000 km. After checking twice, the repairman said it was very thick. It mainly depends on the road conditions. Now I call the police to change the brake pads when the car is more than 30000 km. Later, I moved and adjusted my work. It is basically the outer ring and expressway every day. Now it is 110000 km, and I haven't prompted to change the brake pads for the second time.

Fifth, depending on the situation, some brake discs can be replaced at 150000 kilometers, but almost 100000. Don't consider replacing the brake discs twice. Have you ever seen a disc replacement at 20000 kilometers? If the running in is good, the brake will not shake after replacing the new brake pad. Do not replace it. If the brake shake affects the braking distance, it is recommended to replace it. The disc is not reliable. Brake pads are not expensive online

What should I do if the brake disc rusts and makes a strange noise after washing the car?

If you want to know if there is a solution, you must first understand the characteristics of the brake disc. The brake disc is made of gray cast iron. When the brake disc of this material contacts with the air after encountering water, it will produce chemical reaction and rust. Of course, this problem will not only appear on low-end models, but also on all cars on the market, including the brake discs installed on many luxury cars, In this case, it will also rust.

There is a strange noise when driving because the rust on the brake disc and the friction sound of the brake pads. In fact, you don't have to care about it. When the rust on the brake disc is rubbed off, it will naturally stop ringing. If you want to stop it quickly, you can eliminate this noise by stepping on the brake. However, in order to prevent the brake disc from rusting, you must not apply lubricating grease on the brake disc, which will directly lead to the failure of your vehicle's brake system.
