Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Wear gloves and safety goggles.

2. Inspect Brake Lines and Components

Tools Required: Wrench set, brake line wrench
Steps:
- Raise the vehicle using a jack and secure it on jack stands.
- Carefully inspect all brake lines for cracks or corrosion.
- Check brake hoses for wear or bulging.
- Inspect brake calipers for leaks and ensure they are properly mounted.

3. Replace Faulty Components

Tools Required: Socket set, torque wrench, brake fluid
Steps:
- If leaks are found in any brake lines or hoses, replace with new ones.
- If the brake caliper is leaking, remove the wheel and caliper, then replace the caliper.
- For a faulty master cylinder, disconnect the brake lines, remove the old master cylinder, and install the new one. Torque bolts to manufacturer specifications.

4. Refill and Bleed Brake System

Tools Required: Brake fluid, bleed kit
Steps:
- Refill the brake fluid reservoir with the recommended brake fluid type.
- Bleed the brake system starting from the farthest wheel from the master cylinder to the closest. Ensure there are no air bubbles in the lines.

5. Final Inspection

Tools Required: Visual inspection tools
Steps:
- Inspect all connections for tightness.
- Check for leaks after refilling and bleeding the system.
- Lower the vehicle and test the brake pedal feel before taking the vehicle for a test drive.
