Is It Normal for Car Tires to Rust?

[LaLyla]

Automotive brake discs are generally made of cast iron, so they will gradually rust after the vehicle has been parked or stored for a period of time. This is a normal phenomenon and does not indicate any quality issues with the brake discs. Detailed explanations are as follows: 1. Rust condition: If the rust on the brake discs is minimal, no special treatment is necessary, as minor rust spots will be removed through braking during normal driving. However, severe rust can cause vibrations or shaking during braking, such as brake pad vibration, steering wheel vibration or shaking, or body vibration. 2. Timely maintenance: Severe rust is difficult to remove through braking alone, and even if the rust is removed, uneven thickness of the brake discs may still cause braking vibrations. Therefore, it is recommended to perform maintenance on the brake discs every two months to prevent the rust from becoming too severe.
