What Causes Rust on the Lavida Brake Discs?
2 Answers
Rust on the Lavida brake discs is a normal phenomenon. Causes of rust: In fact, rust on the brake discs does not mean the brake discs are actually rusting. It is because the car has been in a humid environment for a long time, and with prolonged use, the car is bound to encounter bumps and scratches. The surface of the brake discs is inevitably damaged with scratches and other marks. Then, when washing the car outside, exposure to poor-quality cleaning agents containing acids or alkalis can lead to corrosion and rust on the wheel hubs. Treatment methods: For general wheel hub rust, you can first use very fine sandpaper dipped in water to gently sand off the rust spots, completely clean the area, and then apply a layer of primer. This ensures the rust does not spread or worsen. If it's a new scratch, you can clean it and directly apply the primer. Most vehicles come with a small can of original paint. Although this treatment may not look great, it is not a big issue for very small areas.
Rust on the Lavida brake discs is actually quite common, and I've personally repaired many similar cases. Most brake discs are made of iron, which is prone to oxidation. Once it rains or the air humidity rises, rust spots easily form on the surface. If the car is parked for a long time, such as not being driven over the weekend, the rust will become more noticeable. However, there's no need to worry too much—this doesn't affect driving safety because when you start the car and apply the brakes, the heat generated by friction will directly grind off the rust. Typically, driving just a kilometer or two will restore the discs to a clean state. If the rust is particularly thick or appears frequently, it might be worth checking whether the vehicle is exposed to a salt spray environment or inspecting the brake discs' anti-corrosion coating for issues. Overall, this isn't a major malfunction. Regularly driving short distances can effectively reduce the chance of rust, saving both money and hassle.
