Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools: socket set, brake fluid, brake cleaner, torque wrench, OBD-II scanner.

2. Check and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir (usually near the driver's side).
2. Remove the cap and inspect the fluid level.
3. If low, add the recommended brake fluid type (usually DOT 4).
4. Replace the cap securely.

3. Inspect Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads for thickness (should be at least 3mm); replace if worn.
4. Check rotors for grooves or uneven wear; replace if necessary.
5. Clean brake components with brake cleaner before reassembly.

4. Bleed Brake System (if necessary)

Sub-steps:
1. Locate the brake bleeder valves on each brake caliper.
2. Attach a clear tubing to the bleeder valve and place it in a container.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve to allow air and fluid to escape; close the valve before releasing the brake pedal.
5. Repeat until all air is out of the system; ensure the brake fluid level in the reservoir is maintained.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
2. Lower the vehicle and perform a test drive to ensure brakes are functioning properly.
3. Monitor the brake warning light; it should extinguish if the issue is resolved.
