Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and visually inspect the fluid level; add the appropriate brake fluid (DOT 3 or DOT 4) if low.
Check for any signs of contamination (e.g., discoloration or debris).

3. Brake Booster Check

If the brake booster is suspected to be faulty, remove it from its mounting.
Inspect the vacuum line for cracks or disconnections; replace if necessary.
If the brake booster is defective, replace it with a new unit.

4. Brake System Inspection

Remove the wheel to access the brake components.
Inspect brake pads and rotors for wear; replace if pads are worn beyond manufacturer's specifications (usually 1/8 inch).
Use a torque wrench to tighten caliper bolts to manufacturer specifications.

5. Reassemble

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Dispose of any old brake fluid and parts in accordance with local regulations.
