What Causes Rust on the Lavida Brake Discs?

[GriffinLee]

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.

As a Lavida owner, I often notice rust on the brake discs, especially after summer rainstorms when the car is parked in the garage overnight—a layer of red rust appears, which was quite startling at first glance. Later, I asked friends about it, and they said it's perfectly normal; iron components will oxidize and rust under moisture exposure, nothing to worry about. I tried driving the car a few times and lightly applying the brakes—within seconds, the rust was gone, and the car looked as good as new. Unless the rust becomes severe enough to affect braking efficiency, there's no need for repairs. A simple tip is to avoid parking in damp areas when possible. An easy solution is to take a short drive on the highway over the weekend—the rust will be polished off effortlessly, saving time and hassle.

I think brake disc rust is quite common on cars like the Lavida, because the material is iron, which easily reacts and oxidizes when exposed to water. Especially during the rainy season or when the car is parked for a long time without use, rust will develop. After driving, the rust will quickly wear off when the brakes are applied, and it's not a problem. Just maintain normal driving habits.
