Is It Normal for Brake Pads to Have Rust?

[ElizaAnn]

Brake pad rust is a normal phenomenon. Harsh Environment: Most car brake discs are made of cast iron and are exposed to the elements for long periods, enduring rain, snow, and harsh conditions. As a result, surface rust is inevitable. Rust can affect the braking performance of the car and needs to be addressed promptly. Minor Rust: Light rust can usually be removed through normal braking. The friction between the brake pads and the brake disc during braking will gradually wear away the rust, restoring normal functionality. Severe Rust: When the brake disc is severely rusted, normal braking may not be sufficient to remove the rust. The rust on the brake disc can cause an uneven surface, leading to steering wheel vibration and unusual noises during braking. In such cases, the brake pads may need to be removed and sanded down, though this will shorten the lifespan of the brake disc. The best solution is to replace the brake disc entirely.
