Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Check Brake Fluid

Open the hood and locate the master cylinder.
Remove the cap and check the brake fluid level.
If low, add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Inspect Brake Lines and Connections

Visually examine all brake lines and connections for signs of leaks or damage.
Tighten any loose connections and replace any damaged lines.

4. Test Brake Booster

With the engine off, press the brake pedal several times to deplete vacuum in the booster.
Start the engine and press the brake pedal; it should feel softer and move further down.
If the pedal remains hard, the brake booster may be faulty.

5. Replace Brake Booster (if necessary)

Disconnect the negative battery terminal.
Remove any components obstructing access to the brake booster (such as the air intake duct).
Disconnect the brake lines from the master cylinder.
Unbolt the brake booster from the firewall and remove it.
Install the new brake booster in reverse order of removal, ensuring all bolts are tightened to the manufacturer's specifications (typically 15-20 ft-lbs).
Reconnect the brake lines and ensure they are secure.
