The change frequency of brake disk

In theoretically: The biggest wear limit of brake discs is 2 mm, the new brake discs must be replaced after limit. But in actual, almost all owners are not strictly carried out the standard. The change frequency also is measured according to the driving habits. The measured standard as follows:

1 According to the change frequency of brake pads.  If the pads replacement with high frequency, we suggestion check the thickness of the brake discs. After all, the faster consumption of brake pads means frequent braking.

So you’d better check the brake discs regularly.

2 According to wear condition to decide: except normal wear, the quality and the wear caused by foreign body in normal use process. If the brake disk was foreign body wear some deeper in the ditch, or disk wear a deviation (some local thin, some local thick) would recommend replacing, because this kind of wear difference after deviation will directly influence our safe driving.
