How Often Should the Passat Brake Discs Be Replaced?

[DelilahDella]

There is no fixed replacement cycle for Passat brake discs. When the wear indicators disappear, it indicates that the brake discs need to be replaced. Below is relevant information: 1. Minor Rust: This can be polished away through normal braking. Friction between the brake pads and brake discs will occur, and after multiple braking actions, the rust can be removed, restoring normal functionality. 2. Severe Rust: When the brake discs exhibit severe rust, normal braking cannot remove the rust. The rust on the brake discs will create an uneven surface, leading to steering wheel vibration during braking and unusual noises. In such cases, the brake pads can be removed for polishing, but this will shorten the lifespan of the brake discs. It is best to replace them with new brake discs.
