Tools Required: None
Visually inspect all brake lines and hoses for any signs of fluid leaks or damage.
If leaks are found, replace the affected lines or hoses.

5. Verify Brake Light Switch

Tools Required: Multimeter
Locate the brake light switch near the brake pedal.
Use a multimeter to test the switch for continuity when the pedal is pressed.
Replace the switch if it does not function correctly.

6. Reset Brake Warning Light
