Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and visually inspect the brake fluid level.
3. If low, add the correct type of brake fluid (consult owner's manual for specifications).
4. Replace the cap securely.

3. Inspect Brake Lines and Components

Sub-steps:
1. Examine all brake lines for any signs of leaks, bulges, or damage.
2. Check brake calipers for leaks around seals.
3. If leaks are found, replace the damaged lines or calipers as necessary.

4. Bleed Brake System

Sub-steps:
1. Use a brake bleeder kit to remove air from the brake lines.
2. Start with the wheel furthest from the master cylinder (usually the rear passenger side).
3. Attach the bleeder hose to the bleeder valve and open the valve while someone presses the brake pedal.
4. Close the valve before releasing the brake pedal.
5. Repeat for each wheel in the correct order until no air bubbles are present.

5. Inspect and Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the wheel and inspect the brake pads for thickness.
2. Check the condition of the rotors for wear or scoring.
3. Replace pads and/or rotors if they are below manufacturer specifications.
4. Reassemble the wheel and lower the vehicle.
