Solution

1. Preparation

Tools Required: OBD-II scanner, brake fluid, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface, and engage the parking brake. Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir (typically near the driver's side of the engine bay).
2. Remove the reservoir cap and check the fluid level. If it's low, top it up with the manufacturer-recommended brake fluid (DOT 4 or as specified).
3. Replace the reservoir cap securely.

3. Inspect Brake Components

Sub-steps:
1. Remove the wheels to access brake calipers and rotors.
2. Inspect brake pads for thickness; replace if they are worn below the manufacturer’s specifications (usually 3mm).
3. Check rotors for scoring or warping; replace if necessary.
4. Inspect brake lines for any signs of damage or leaks.
5. If any components are damaged, follow removal and replacement procedures based on your vehicle's service manual.

4. Test and Replace Brake Switch (if necessary)

Sub-steps:
1. Locate the brake warning light switch, usually found on the brake pedal assembly.
2. Disconnect the electrical connector and use a multimeter to test the switch for continuity.
3. If the switch is faulty, replace it with a new one, ensuring it is properly aligned and connected.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheels and torque the lug nuts to the manufacturer’s specification.
2. Reconnect the battery.
3. Start the vehicle and check if the brake warning light is still illuminated.
