[BrynleeRose]

Brake disc rust is not a serious issue and is a normal phenomenon. The rust on brake discs is mainly caused by the vehicle being parked for extended periods, excessively humid air, or rain and snow. When parking the vehicle, it is advisable to choose a covered or relatively dry location to some extent avoid rust. Simply put, a brake disc is a round disc that rotates as the vehicle moves. The brake caliper clamps the brake disc to generate braking force, slowing down or stopping the vehicle when the brakes are applied. The method for replacing a brake disc is as follows: 1. Open the engine compartment and check the brake fluid level to prevent overflow during replacement; 2. Remove the wheel where the brake is located and the bolts of the brake caliper; 3. Take off the old brake disc, install the new one, tighten the guide bolts, and complete the replacement.
