Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Brake Fluid Inspection

Sub-steps:
- Open the hood and locate the brake master cylinder.
- Check the brake fluid level; if low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
- Inspect the fluid for contamination or discoloration.

3. Bleed the Brake Lines

Sub-steps:
- Locate the brake bleeder valves on each brake caliper.
- Use a wrench to open the bleeder valve on the farthest caliper from the master cylinder.
- Have an assistant press the brake pedal while you open the valve; close the valve before they release the pedal.
- Repeat this process until clear fluid without air bubbles flows from each caliper.
- Ensure to keep the master cylinder topped off during the bleeding process.

4. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake assembly.
- Examine the brake pads for wear; replace if thickness is below 3mm.
- Check the rotors for warping or scoring and replace if necessary.

5. Test Brake Booster

Sub-steps:
- With the vehicle off, pump the brake pedal several times to deplete vacuum.
- Start the engine while applying pressure to the brake pedal; it should drop slightly indicating the booster is functioning.
- If no drop occurs, the brake booster may need replacement.
