What does a sun exclamation mark on the dashboard mean?

[OTucker]

On the dashboard, a sun exclamation mark is the brake pad warning light, indicating a brake pad fault, which serves as a reminder to replace the brake pads. When the front brake pads are nearing their wear limit, this warning will appear. It is recommended to check whether the brake pads need replacement. If the brake pads do not require replacement, adding some brake fluid may suffice. Before traveling, it is essential to inspect the braking system for normal operation, including the wear level of the brake pads. Additionally, ensure that the power steering fluid is sufficient. Special attention should be paid to the dust cover of the brake system's wheel cylinder. If this component is damaged and allows dust to enter, it can cause the piston to malfunction, leading to an increased braking distance when applying the brakes. If water enters this component, it can mix with the brake fluid, resulting in brake failure.
