Why is my parking brake warning light still on?
A persistent parking brake warning light is often caused by unresolved diagnostic trouble codes stored in the computer module or a stuck physical switch rather than just low fluid levels. Without clearing these underlying fault codes or resetting the system, the dashboard warning will remain illuminated even after repairs are made.
