Solution

1. Preparation

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

2. Inspect Brake Fluid Level

Sub-steps:
- Open the hood and locate the brake master cylinder.
- Remove the cap and check the brake fluid level; it should be between the minimum and maximum marks.
- If low, top up with the appropriate brake fluid type (DOT 4 or as specified in the owner's manual).

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container for old brake fluid.
Sub-steps:
- Start at the wheel farthest from the master cylinder (usually the passenger rear).
- Attach the clear tubing to the bleeder valve and place the other end in a container.
- Have an assistant press the brake pedal while you open the bleeder valve; close it once fluid flows out.
- Repeat until no air bubbles are present, then move to the next wheel.
- Ensure fluid levels remain topped up during the process.

4. Inspect the Brake Booster

Sub-steps:
- Visually check the brake booster for any visible cracks or damage.
- Listen for any hissing sounds while pressing the brake pedal, indicating a vacuum leak.
- If necessary, disconnect the vacuum hose and check for blockages.

5. Test the Brake Booster Operation

Sub-steps:
- With the engine off, press the brake pedal several times to deplete any vacuum stored in the booster.
- Start the vehicle while maintaining pressure on the brake pedal.
- If the pedal sinks slightly when the engine starts, the brake booster is likely functioning correctly.

6. Check the Brake Master Cylinder

Sub-steps:
- Inspect the master cylinder for any leaks around the seals.
- If leaking or the internal seals are damaged, replace the master cylinder with a new or remanufactured unit.
