Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Inspect and Repair Leaks

Sub-steps:
1. Visually inspect all brake lines and components for leaks.
2. If any leaks are found, replace the damaged brake lines or components.
3. Tighten any loose connections to prevent further leaks.

3. Replace Brake Fluid

Tools Required:
- Brake fluid (DOT 3 or as specified in the owner's manual)
Sub-steps:
1. Remove the master cylinder reservoir cap.
2. If the fluid is dirty or low, drain the old brake fluid.
3. Refill with fresh brake fluid to the appropriate level.

4. Bleed the Brake System

Tools Required:
- Brake bleeder kit or clear tubing and a container
Sub-steps:
1. Starting with the wheel furthest from the master cylinder, have an assistant pump the brake pedal several times.
2. Open the bleeder valve on the brake caliper to allow air and fluid to escape.
3. Close the valve once the fluid runs clear and no air bubbles are present.
4. Repeat for all wheels in the correct order (typically: right rear, left rear, right front, left front).
5. Recheck and top off the master cylinder fluid level after bleeding.

5. Test the Brake System

Sub-steps:
1. Reinstall the master cylinder reservoir cap.
2. Start the vehicle and test the brake pedal feel before driving.
3. Ensure the pedal feels firm and responsive.
