In theory, the brake disc does not need maintenance, but in fact it is not impossible to maintain it. For example, apply some high temperature grease when the brake disc and the bearing are in contact to avoid rusting the brake disc and the hub in the future.

But it doesn't matter whether the brake disc is maintained or not. The brake system mainly maintains the brake cylinder pin! The brake cylinder pin is one of the more important parts. If it gets stuck, it will cause the brake to drag and brake eccentric wear.

Generally, when the brake disc needs to be repaired, the steering wheel shakes or the body shakes only when the brake is stepped on at high speed. At this time, the brake disc is generally deformed and the runout exceeds the standard value, so the brake will shake.

At this time, if the thickness of the brake disc is enough, you can scrape a knife, and then measure whether the runout is within the normal range. If it is within the normal range, then there will be no problem. Continue to scrape within the normal range. If the limit wear value of the brake disc is exceeded, then replace the brake disc. Generally, the front brake disc is deformed more.

In short, there is no special maintenance for the brake disc, but there is still a place for maintenance of the brake system. Let's write about it here!
