Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check Brake Fluid Level

Remove the cap from the brake fluid reservoir.
Inspect the fluid level; top off with the recommended brake fluid (DOT 3 or DOT 4 depending on specifications).

3. Inspect Brake Lines and Master Cylinder

Visually inspect all brake lines for signs of leaks or damage.
Check the master cylinder for leaks or corrosion.
Replace any damaged brake lines or a faulty master cylinder as necessary.

4. Test Brake Booster

Use a vacuum gauge to connect to the brake booster.
Start the engine and check if the gauge indicates a vacuum of 18-20 inHg.
If the vacuum is low or absent, the brake booster is likely faulty and needs replacement.

5. Replace Brake Booster (if necessary)

Disconnect the vacuum line from the brake booster.
Remove the nuts securing the brake booster to the firewall.
Disconnect the pushrod from the brake pedal.
Install the new brake booster by reversing the removal steps.
Reconnect all lines and ensure all connections are secure.
