Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Socket set, vacuum gauge, OBD-II scanner, brake fluid.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder reservoir.
Remove the cap and visually inspect the brake fluid level.
If fluid is low, top off with the recommended brake fluid type (DOT 3 or DOT 4).

3. Inspect Brake Booster

Locate the brake booster and inspect for any physical damage or signs of fluid leaks.
Check the vacuum hose connected to the brake booster for cracks or disconnections.

4. Testing the Brake Booster

With the engine off, pump the brake pedal several times to deplete the vacuum.
While holding the pedal down, start the engine. The pedal should drop slightly; if it does not, the booster may be faulty.

5. Replacing the Brake Booster (if necessary)

Disconnect the negative battery terminal.
Remove the master cylinder from the brake booster (undo the mounting bolts and pull it off).
Unbolt the brake booster from the firewall (typically requires a socket set).
Install the new brake booster in reverse order of removal, ensuring all connections are tight and secure.
Reattach the master cylinder and refill brake fluid if necessary.
