Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required:
- Brake fluid
- OBD-II scanner
- Wrench set
- Brake bleeder kit
- Safety glasses
- Gloves

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, top it off with the appropriate brake fluid type (DOT 3 or DOT 4).
Inspect the brake lines for any signs of leaks.

3. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the passenger side rear).
Attach a brake bleeder kit to the bleeder valve on the brake caliper.
Have an assistant press the brake pedal while you open the bleeder valve to release air.
Close the valve before your assistant releases the pedal.
Repeat this process for each wheel in the order: passenger side rear, driver side rear, passenger side front, driver side front.
Ensure brake fluid does not run low during the process.

4. Inspect Brake Components

Remove the wheel to access the brake components.
Inspect the brake pads for wear; replace if they are below the minimum thickness.
Check the brake rotors for warping or damage; replace if necessary.

5. Test the Brake Booster

With the engine running, press the brake pedal several times to deplete the brake booster.
Hold the pedal down and start the engine; the pedal should drop slightly if the booster is functioning properly.
