Is It Normal for Wheel Brake Discs to Rust?

[KendraLynn]

It is normal for car brake discs to rust. Here is a detailed introduction about it: 1. Slight rust: Slight rust often occurs. For example, after the car is left out in the rain overnight or after washing when the car is not dried properly, slight rust can easily form. In such cases, continuous braking while driving can help remove the rust, as the brake disc rubs against the brake caliper during braking, and the rust will be worn off after multiple brakes. 2. Severe rust: If the brake disc has severe rust, the entire surface of the brake disc will have a relatively thick layer of rust. Stubborn rust can also accelerate the wear of the brake pads, so it is necessary to take the car to a repair shop to have the brake disc polished.
