How to Deal with Brake Pad Rust?

You can use the method of continuous braking while driving to remove it. While driving, gently press the brake to let the friction between the brake pads and the brake disc 'polish' the surface. Drive the vehicle into the repair shop, remove the brake disc, and use sandpaper to grind off the rust. After proper installation, conduct a road test.

I remember one time after my car was parked in the rain, the brake pads rusted. When I started driving and pressed the brakes, it didn't feel quite right. So I drove slowly for a short distance and gently pressed the brake pedal a few times. After a few minutes, the rust wore off. This is quite common, especially when parked in humid conditions for several days—it's not a big issue. However, if the rust is severe, the brakes may make unusual noises or perform poorly, in which case it's necessary to visit a repair shop to check if the pads are too worn or pose a safety hazard. Prevention is better than cure, so now I try to park in dry places and wait for the car to dry after washing before parking it. Driving safety comes first—never ignore small issues that could turn into big problems. Regular maintenance can reduce such occurrences.

When I first started driving, I often encountered rust on the brake pads, especially after parking outdoors for a few days during the rainy season. The solution is simple: after starting the engine, shift to a low gear and coast slowly for a short distance, then gently press the brakes a few times. The rust is usually rubbed off, and normal function is restored. This method is free and hassle-free, as long as the rust isn’t too severe. Prevention is key—avoid parking in damp areas, and after washing the car, park indoors or cover it with a moisture-proof cloth. If the brakes feel abnormal, such as being sluggish or making noise, it might indicate damaged pads or severe rust. In such cases, promptly consult a reliable mechanic to avoid increasing risks.

Brake pad rusting is a normal phenomenon, especially after parking in humid environments. If not severe, driving slowly for a few minutes and gently applying the brakes a couple of times can remove the rust layer through friction. However, excessive rust can reduce braking efficiency or cause abnormal noises, at which point it's necessary to visit a professional shop to check pad thickness or replace them to ensure safety. Developing good habits, such as avoiding prolonged parking in rainy areas, can significantly reduce occurrence. Avoid DIY attempts to prevent system damage, as maintenance is key to ensuring driving safety.
