How to Deal with Rust on the Disc Inside the Wheel?

If there is only slight rust on the surface, you can remove it by continuously applying the brakes while driving. Here is some relevant information about the wheel hub: 1. Introduction: The wheel hub is the rotating part of the wheel rim connected by pillars inside the tire, which is the metal component mounted on the axle that supports the tire. It is also called the wheel rim, steel rim, or tire ring. Wheel hubs come in various types based on diameter, width, forming method, and material. 2. Types of Wheel Hubs: The wheel hub is also called the wheel rim. Depending on the characteristics and requirements of different vehicle models, the surface treatment process of the wheel hub can vary, mainly divided into painting and electroplating. For ordinary vehicle models, the wheel hub's appearance is less of a consideration, with good heat dissipation being a basic requirement. The process generally involves painting treatment, which includes spraying and then baking, making it cost-effective with vibrant colors and long-lasting durability. Even when the vehicle is scrapped, the color of the wheel hub remains unchanged.

The round disc inside the wheel is likely referring to the brake disc, and rust is a common occurrence, especially in humid or rainy areas. I suggest first checking the extent of the rust. If it's just surface rust, you can try handling it yourself. Use a wire brush to gently scrub off the rust layer, then spray on a specialized rust inhibitor—something like WD-40 works well. After that, rinse it clean with water. If the rust is too deep, it might have damaged the brake disc, affecting safe driving, so don’t skimp on this expense. It’s best to take it to a repair shop for a professional inspection to see if replacement is necessary. When parking, avoid puddles, and after washing your car, dry the wheels thoroughly to prevent rust. Remember, don’t be too lazy—regularly maintain the wheel components to prevent small issues from becoming big problems. Safety first—always ensure the car is parked and turned off before handling anything.

I've been driving for years and have encountered the issue of rust on the round discs inside the wheels a few times. Typically, the brake discs are exposed and prone to rust when they come into contact with rainwater or road salt in winter. Dealing with it isn't difficult: first, use a cleaner to remove dirt, then lightly sand off the rust with sandpaper, being careful not to damage the disc surface. After that, apply some rust-proof paint or simply spray a layer of protective agent and let it dry thoroughly. If the rust is severe enough to cause deep grooves or looseness, don't force it—take it to a technician to replace the parts. Don't delay this; brake failure is no joke. When parking, choose a dry spot to avoid constant exposure to rain, and rinse the brake area thoroughly when washing the wheels. Make it a habit to check the tires and wheel components regularly to reduce unexpected risks.

The rusty disc inside the wheel might indicate an issue with the brake components. As a novice driver, I believe the safest approach is not to tamper with it randomly. Take a photo and send it to a mechanic for advice. If the rust isn't severe, they might suggest cleaning it yourself—use a brush, apply some rust remover, and then wipe it clean with a damp cloth. If there's extensive rust, don't delay; get it repaired immediately to avoid compromising driving safety. Try to avoid driving on salted roads frequently, and pay extra attention to the wheels when washing the car.

That rusty disc inside the wheel doesn't look good and affects the mood. I often handle this myself: prepare some mild detergent and a soft-bristled brush, first thoroughly rinse the wheel to remove dirt. Then use fine sandpaper to polish the rust spots, but don't apply too much force to avoid scratching. After that, spray some rust-proof spray as a protective layer and let it air dry naturally. If the rust is deep, seek help from a professional shop. Usually, avoid parking in the rain and dry the wheels promptly after washing the car. This can also be a fun weekend DIY project to protect the wheels and keep your beloved car looking shiny and beautiful.
