Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical issues during repairs.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, clean cloth
Check the brake fluid reservoir; if low, clean the area around the cap before removing it to avoid contamination.
Top off with the appropriate brake fluid type (usually DOT 3 or DOT 4).
Reconnect the battery terminal and check if the warning light has turned off.

3. Brake Pad and Rotor Inspection

Tools Required: Jack and jack stands, lug wrench, socket set
Raise the vehicle and remove the wheels using a lug wrench.
Inspect brake pads for wear; if the thickness is less than 3mm, replace them.
Check rotors for scoring or warping; replace if necessary.
Reassemble the brakes and wheels, ensuring all bolts are torqued to manufacturer specifications.

4. Brake Line Inspection and Repair

Tools Required: Wrench set, brake line flaring tool (if needed), brake line replacement
Inspect all brake lines and hoses for leaks or damage.
If any line is compromised, replace it with a new line, ensuring proper flaring at the ends.
Bleed the brake system to remove any air that may have entered.

5. Brake Light Switch Inspection

Tools Required: Multimeter
Locate the brake light switch, usually near the brake pedal.
Use a multimeter to test the switch for continuity while pressing the brake pedal.
If faulty, replace the switch and reconnect the electrical connector.
