Solution

1. Preparation

Gather necessary tools and safety gear.
Park the vehicle on a flat surface and turn off the engine.
Engage the parking brake and wear safety goggles and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the fluid level; add the recommended brake fluid type (DOT 3 or DOT 4).
3. If the fluid is contaminated, proceed to flush the system.
4. Use a turkey baster or brake fluid extractor to remove old fluid from the reservoir.
5. Refill with new brake fluid until it reaches the "full" mark.

3. Identify and Repair Leaks

Sub-steps:
1. Use a flashlight to inspect brake lines and connections for signs of fluid leakage.
2. Tighten any loose connections or replace damaged lines with new ones.
3. If leaks are found at the calipers or master cylinder, remove the affected component.
4. Replace seals or gaskets as needed, or replace the entire component if severely damaged.

4. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Check brake pads for wear; replace if they are less than 3mm thick.
3. Inspect rotors for scoring or damage; replace if necessary.
4. Install new pads and reassemble the brake components.

5. Bleed the Brake System

Sub-steps:
1. Begin at the wheel farthest from the master cylinder (typically the right rear).
2. Use a brake bleeder kit to open the bleeder valve and allow fluid to escape until no air bubbles are present.
3. Close the valve and repeat on the remaining wheels in the order: right rear, left rear, right front, left front.
4. Recheck fluid level in the reservoir and top off if needed.
