Does the Malibu XL's brake discs rust?

[VanNorah]

The Malibu XL's brake discs can rust. They are prone to rusting after damp or rainy weather. If the car's brake discs are slightly rusted, they can be polished and buffed; severe rusting may require replacement of the brake discs. Simply put, a brake disc is a round disc that rotates as the car moves. The brake caliper clamps the brake disc to generate braking force—when you press the brake pedal, it clamps the disc to slow down or stop the vehicle. The advantages of disc brakes are as follows: 1. Disc brakes dissipate heat better than drum brakes, reducing the risk of brake fade and failure during continuous braking. 2. The thermal expansion of brake discs along the thickness direction is minimal, so heat-induced size changes do not increase the brake pedal travel. 3. Disc brake systems respond quickly, allowing high-frequency braking, making them more suitable for ABS requirements. 4. Unlike drum brakes, disc brakes lack friction self-boosting effects, ensuring more balanced braking force between the left and right wheels. 5. Better drainage in disc brakes reduces the likelihood of poor braking due to water or mud. 6. Compared to drum brakes, disc brakes have a simpler structure, making automatic gap adjustment easier and maintenance more straightforward.
