Check brake calipers and wheel cylinders for dampness or fluid accumulation.
If leaks are found, replace the affected lines or components as necessary.

4. Replace Brake Light Switch (if faulty)

Locate the brake light switch near the brake pedal.
Disconnect the electrical connector from the switch.
Remove the switch from its mounting bracket (usually secured with a nut or screw).
Install the new switch in reverse order and reconnect the electrical connector.
