Does Rust on Car Brake Pads Have Any Impact?
1 Answers
Generally speaking, this type of rust does not affect normal braking. However, severe rust can impair braking performance. Rust on brake discs is a normal phenomenon, as car brake discs are typically made of cast iron, making them highly susceptible to rust in humid weather, and it also depends on the local environment. Below are the main reasons for abnormal noises in disc brake vehicles: Metal hard spots on brake pads: If there are tiny metal particles on the brake pads, they can produce a squealing sound when braking. Severe wear on brake discs: Over time, deep grooves can form on the brake discs where the brake pads make contact, leading to abnormal noises when braking.
