Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid any electrical shorts.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, rags
Check the brake fluid level in the master cylinder. If low, top off with the manufacturer's recommended brake fluid.
If the fluid appears contaminated or old, perform a brake fluid flush.

3. Test and Replace Brake Booster

Tools Required: Vacuum gauge, socket set, wrenches
Locate the brake booster under the hood. Attach the vacuum gauge to the booster’s vacuum line and check for proper vacuum (typically 18-20 inHg).
If vacuum is insufficient, inspect the vacuum line for blockages or leaks. Replace any damaged lines.
If the brake booster is faulty, disconnect the vacuum line and unbolt the brake booster from the firewall. Remove it carefully, noting the position of all connections.
Install the new brake booster by reversing the removal steps, ensuring all connections are secure.

4. Reassemble and Test

Reconnect the vacuum line and any electrical connections.
Reconnect the negative battery terminal.
Start the vehicle and press the brake pedal several times to ensure proper operation.
