Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety glasses and gloves.

2. Inspect and Refill Brake Fluid

Sub-steps:
- Open the hood and locate the brake master cylinder.
- Check the fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4, depending on specification).
- If the fluid is contaminated, proceed to flush the brake system.

3. Bleed Brake Lines

Tools Required: Brake bleeder kit, wrench, clear tubing, container for fluid.
Sub-steps:
- Start with the wheel farthest from the master cylinder (usually the rear passenger side).
- Attach the clear tubing to the bleeder screw and place the other end in the container.
- Have an assistant press the brake pedal while you open the bleeder screw to release air and fluid.
- Close the bleeder screw before the assistant releases the brake pedal.
- Repeat for each wheel in the correct order (rear passenger, rear driver, front passenger, front driver).
- Keep an eye on the brake fluid level in the master cylinder during bleeding to prevent it from going empty.

4. Inspect and Replace Components (if necessary)

Sub-steps:
- Inspect brake pads and rotors for wear; replace if necessary.
- Check the brake lines for any damage; replace if needed.
- Examine the master cylinder for wear or leaks; replace if it shows signs of failure.
