Park the vehicle on a level surface and engage the parking brake.
Gather the following tools:
- Jack and jack stands
- Brake bleeder kit
- Wrench set
- OBD-II scanner
- Brake fluid (DOT 3 or as specified by the manufacturer)

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Check the brake fluid level; if low, fill it to the recommended level.
3. If the fluid is dark or contaminated, drain the old fluid from the system.
4. Replace with new brake fluid.
Tools Required: Brake fluid, funnel.

3. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect all brake lines for signs of wear, corrosion, or leaks.
2. If leaks are found, replace the damaged section of the brake line using a wrench.
3. Ensure all connections are tight and secure.
Tools Required: Wrench set, replacement brake line if damaged.

4. Bleed Brake System

Sub-steps:
1. Begin at the furthest brake from the master cylinder (usually the right rear).
2. Attach the brake bleeder kit to the bleeder valve.
3. Open the valve and have an assistant press the brake pedal several times (hold the pedal down).
4. Close the valve and repeat until no air bubbles are present in the fluid.
5. Move to the next brake (left rear, right front, left front) and repeat the process.
Tools Required: Brake bleeder kit.

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

Sub-steps:
1. Remove the wheel using a jack and jack stands.
2. Inspect brake pads for thickness; replace if worn below 3mm.
3. Inspect rotors for scoring or warping; replace if necessary.
4. Reassemble the brake components and wheel.
Tools Required: Jack, jack stands, socket set.
