Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required:
- Brake fluid (DOT 3 or DOT 4 as specified in owner's manual)
- Clean cloth or paper towels
- Funnel
- OBD-II scanner (optional)

2. Check and Refill Brake Fluid

Sub-steps:
1. Remove the cap of the brake fluid reservoir.
2. Use a funnel to add the appropriate brake fluid until it reaches the "MAX" level mark.
3. Wipe any spilled fluid with a clean cloth to prevent damage to paint or surfaces.
4. Replace the reservoir cap securely.

3. Repair Leaks (If Found)

Sub-steps:
1. Identify the source of the leak in brake lines, hoses, or the master cylinder.
2. Replace any damaged brake lines or hoses with OEM parts.
3. For the master cylinder, remove it from the vehicle by unbolting it and disconnecting the brake lines.
4. Install the new master cylinder and ensure all connections are tight. Torque specifications can be found in the service manual.
5. Bleed the brake system to remove any air bubbles.

4. Inspect and Replace Brake Components (If Necessary)

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear. If thickness is below 3mm, replace them.
3. Check calipers for functionality and replace if they are leaking or frozen.
4. Inspect rotors for scoring or warping; replace if necessary.
