Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir (usually near the back of the engine bay).
Remove the cap and check the fluid level. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified).
Inspect for leaks around the reservoir and brake lines.

3. Inspect Brake Components

Remove the wheel(s) if necessary to access the brake assembly.
Inspect the brake pads, rotors, and calipers for wear or damage.
Check for any signs of fluid leaks around brake lines or the master cylinder.

4. Replace Brake Light Switch (if necessary)

Locate the brake light switch, typically found near the brake pedal.
Disconnect the electrical connector and remove the switch using a socket set.
Install the new brake light switch and reconnect the wiring.

5. Reassemble and Test

Reassemble any components that were removed.
Ensure all connections are secure.
Start the vehicle and press the brake pedal to check if the brake light illuminates properly without blinking.
