Solution

1. Preparation

Tools Required:
- Wrench set
- Brake fluid
- OBD-II scanner
- Brake bleeder kit
- Jack and jack stands
Safety Warnings:
- Disconnect the battery before working on electrical systems.
- Allow the vehicle to cool down if it has been running.

2. Inspect and Replace Brake Fluid

Check the brake fluid level in the master cylinder reservoir.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid appears discolored or contaminated, drain and replace it completely.
Use a brake bleeder kit to ensure any air is purged from the brake lines.

3. Inspect Brake Components

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake components.
Inspect the brake pads for thickness; replace if worn down to the manufacturer's specifications.
Check the rotors for scoring or warping; replace if necessary.

4. Bleed the Brakes

Starting from the wheel farthest from the master cylinder, attach the brake bleeder kit.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and old fluid, then close it before the pedal is released.
Repeat for each wheel, moving from farthest to closest to the master cylinder.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Reconnect the battery.
Conduct a test drive to ensure the brake pedal feels firm and responsive.
