Brake disc shaking is a problem that many car owners may encounter while driving. When a vehicle shakes during braking, many people's reaction is that there is a problem with the brake pads. However, brake disc shaking is not necessarily caused by brake pads, it may be caused by various reasons. The following is a detailed analysis of the causes of brake disc vibration.
1. Brake disc deformation
Brake disc deformation is one of the common causes of brake shake. The brake disc may deform during frequent braking at high temperatures or prolonged parking braking. Deformed brake discs can cause uneven contact between brake pads and discs during braking, leading to vehicle shaking. In addition, if there are quality problems with brake discs during the manufacturing process, such as insufficient material hardness or improper surface treatment, they are also prone to deformation during use.
2. Uneven wear of brake pads
Uneven wear of brake pads can also cause brake shaking. If the material of the brake pads is uneven or installed improperly, it may cause uneven contact between the brake pads and brake discs, leading to shaking. In addition, brake pads that are too hard or contain impurities may also cause shaking. It is recommended to regularly check the wear of brake pads and replace severely worn brake pads in a timely manner.

3. Improper installation
Improper installation of brake discs or brake pads may also cause shaking. For example, if the installation between the brake disc and the wheel hub is not tight, or if the screws of the brake disc are not tightened, it may cause the brake disc to shake when rotating at high speeds. It is recommended to ensure correct installation, tighten screws, and perform appropriate running in when replacing brake discs or pads.
4. Wheel hub issues
Deformation or imbalance of the wheel hub can also affect the normal operation of the brake disc, causing shaking during braking. If the wheel hub is deformed or unbalanced, it is recommended to check and replace the wheel hub.
5. Normal wear and tear
Even high-quality brake discs and pads will gradually wear out over time and with frequent use. The unevenness or uneven wear of the brake disc surface may cause shaking during braking. It is recommended to regularly check the wear of brake discs and brake pads, and perform maintenance or replacement in a timely manner.
How to solve the problem of brake disc shaking?
Check the brake disc and brake pads: Check whether the surface of the brake disc and brake pads is flat and the thickness is uniform. If the brake disc is deformed or the brake pads are unevenly worn, it is recommended to replace it.
Reinstall the brake disc: If the brake disc is not installed properly, it is recommended to reinstall it and ensure that the installation between the brake disc and the wheel hub is tight, with screws tightened.
Check the wheel hub: Check if the wheel hub is deformed or unbalanced, and replace it if necessary.
Improving driving habits: Avoid frequent sudden braking and prolonged continuous braking, and reduce excessive use of the braking system.
Regular maintenance: Regularly inspect the brake system, replace worn brake discs and pads in a timely manner, and ensure the normal operation of the brake system.
Brake disc shaking may be caused by various reasons, not necessarily by brake pad issues. Brake disc deformation, uneven wear of brake pads, improper installation, wheel hub issues, or normal wear can all cause brake shake. Regular inspection and maintenance of the brake system can effectively solve the problem of brake disc shaking and ensure driving safety. If brake shake is found during driving, the condition of the brake discs and pads should be checked in a timely manner, and replacement or repair should be carried out if necessary.
