Solution

1. Preparation

Tools Required:
- Wrench set
- Brake fluid
- Brake bleeder kit
- OBD-II scanner
Ensure the vehicle is parked on a level surface and the ignition is off. Engage the parking brake.

2. Inspect and Fix Leaks

Sub-steps:
1. Visually inspect all brake lines and connections for signs of leaking fluid.
2. If leaks are found, replace the damaged brake lines or components as necessary.
Safety Warning: Always wear safety goggles and gloves when working with brake fluid, as it can damage paint and harm skin.

3. Bleed the Brake System

Sub-steps:
1. Starting from the wheel farthest from the master cylinder (usually the right rear), use the brake bleeder kit.
2. Have an assistant press the brake pedal while you open the bleeder valve until fluid flows out without bubbles.
3. Close the valve and repeat this process for the left rear, left front, and then right front wheels.
Torque Values: Ensure all bleeder screws are tightened to manufacturer specifications (typically around 10-12 ft-lbs).

4. Replace Brake Fluid (if necessary)

Sub-steps:
1. If the fluid is contaminated or low, siphon out the old fluid from the master cylinder.
2. Refill with new brake fluid (DOT 3 or DOT 4, as specified by the manufacturer).
3. Repeat the bleeding process to ensure the new fluid is circulated.

5. Inspect Brake Components

Sub-steps:
1. Remove the wheel to inspect brake pads and rotors for wear and damage.
2. Replace any worn brake pads or damaged rotors following manufacturer specifications.
