Is It Normal for Rust to Appear on Tire Brake Pads?

[ChristopherLynn]

Rust on tire brake pads is a normal phenomenon. Most vehicles use cast iron brake discs. Due to the material properties, whenever the external weather is rainy or highly humid, rust may appear on the brake discs if the vehicle has been parked for a certain period or the brakes have not been used for a while. Methods to deal with rust on brake discs: Minor rust: It can be removed through normal braking. The friction between the brake pads and the brake discs will wear off the rust after several brake applications, restoring normal functionality. Severe rust: When the brake discs are severely rusted, normal braking may not be sufficient to remove the rust. The rust on the brake discs can cause uneven surfaces, leading to steering wheel vibrations and unusual noises during braking. In such cases, the brake pads can be removed and polished, but this will shorten the lifespan of the brake discs. It is best to replace them with new ones.
