Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Inspect and Replace Brake Fluid

Sub-steps:
- Open the hood and locate the brake master cylinder.
- Remove the cap and check the brake fluid level; top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
- If the fluid is contaminated (dark or cloudy), proceed to flush the brake fluid system.

3. Address Fluid Leaks

Sub-steps:
- Inspect brake lines and fittings for any signs of wear or damage.
- If leaks are found, replace the damaged lines or fittings. Use a wrench to disconnect and replace lines as needed.
- Tighten all connections securely to prevent future leaks.

4. Bleed the Brake System

Sub-steps:
- Start from the brake furthest from the master cylinder (usually the passenger rear).
- Attach a clear hose to the bleeder valve on the brake caliper and submerge the other end in a container with brake fluid.
- Open the bleeder valve and have an assistant press the brake pedal down slowly. Close the valve before the pedal is released.
- Repeat until no air bubbles are visible in the fluid.
- Continue to the next brake in the order: rear passenger, rear driver, front passenger, and finally front driver.

5. Final Checks

Sub-steps:
- After bleeding, check the brake fluid level in the master cylinder again and top off if necessary.
- Replace the master cylinder cap and ensure all tools are removed from the engine bay.
