Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, brake fluid, cleaning supplies, jack and jack stands.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks. Disconnect the vehicle's 12V battery before performing any electrical work.

2. Address Fault Codes

Use the OBD-II scanner to clear any fault codes associated with the brake system.
Re-scan to verify that no codes reappear after clearing.

3. Inspect and Replace Brake Fluid

Remove the brake fluid reservoir cap.
Check the fluid level and condition; if it appears dark or contaminated, proceed to replace it.
Sub-steps:
1. Siphon out old brake fluid using a turkey baster.
2. Fill the reservoir with fresh brake fluid that meets the manufacturer's specifications (DOT 3 or DOT 4).
3. Replace the cap securely.

4. Inspect Brake Components

Sub-steps:
1. Remove the wheel using a socket set to access the brake components.
2. Inspect brake pads for wear; replace if the thickness is below 3mm.
3. Look at the brake rotors for scoring or excessive wear; replace if necessary.
4. Check calipers for leaks or sticking; replace if damaged.

5. Test Brake Operation

Reinstall the wheel and lower the vehicle.
Reconnect the battery and perform a test drive to ensure the brake system operates correctly.
Pay attention to the brake pedal feel and performance during the test.
