Solution

1. Preparation

Tools Required:
- Brake fluid
- Wrench set
- Brake bleeder kit
- OBD-II scanner
- Clean rags
Park the vehicle on a level surface and engage the parking brake.
Gather all necessary tools and materials.

2. Check and Replace Brake Fluid

Open the master cylinder reservoir cap.
Inspect the brake fluid level; if low, add the recommended brake fluid type (typically DOT 3 or DOT 4).
If the fluid appears dark or contaminated, proceed to replace it.
Sub-steps:
- Remove the old fluid using a brake bleeder or suction tool.
- Fill with new brake fluid until the appropriate level is reached.
- Replace the reservoir cap securely.

3. Inspect and Repair Brake Components

Tools Required:
- Wrench set
Remove the wheels to access brake components.
Inspect brake lines for any signs of wear or leaks; replace any damaged lines.
Check the condition of brake pads and rotors; replace if worn beyond specifications.
Sub-steps:
- If brake pads are worn, remove calipers and replace pads, ensuring proper alignment.
- Replace rotors if they are scored or warped.

4. Bleed the Brake System

Tools Required:
- Brake bleeder kit
Start with the wheel farthest from the master cylinder (usually rear passenger).
Sub-steps:
- Attach the bleeder kit to the brake bleeder valve on the caliper.
- Pump the brake pedal several times and hold it down.
- Open the bleeder valve to release air and old fluid; close the valve before releasing the pedal.
- Repeat until no air bubbles are present in the fluid.
- Move to the next wheel, following the same procedure, until all brakes are bled.
