Solution

1. Preparation

Tools Required: Safety goggles, gloves, socket set, wrench set, brake fluid, rags.
Safety Warnings: Ensure the vehicle is on a level surface and secured with wheel chocks. Disconnect the battery before working on electronic components.

2. Brake Fluid Inspection and Replacement

Open the Hood:
- Locate the brake fluid reservoir.
Check Fluid Level:
- If low, add the appropriate brake fluid specified in the owner's manual.
Inspect for Leaks:
- If the fluid level is low, check all brake lines and connections for leaks.
Replace Fluid if Contaminated:
- If the fluid appears dark or contaminated, perform a brake fluid flush.

3. Brake Line Repair/Replacement

Identify Leaks:
- If leaks are present, mark the affected areas.
Replace Damaged Lines:
- Use a wrench to disconnect the damaged brake line and replace it with a new line.
Bleed the Brakes:
- Bleed the brake system using the two-person method or a vacuum bleeder to remove air from the lines.

4. Master Cylinder Inspection/Replacement

Inspect Master Cylinder:
- If the master cylinder is leaking, remove it by disconnecting the brake lines and unbolting it from the firewall.
Replace with New Unit:
- Install a new master cylinder and reattach the brake lines.
Bleed Brake System:
- Again, ensure the system is bled properly after installation.

5. Brake Component Inspection

Check Brake Pads and Rotors:
