Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Brake Fluid Inspection

Remove the master cylinder reservoir cap.
Check the brake fluid level; if low, top off with the recommended brake fluid (usually DOT 3 or DOT 4).
Inspect for contamination in the fluid. If contaminated, the fluid should be replaced.

3. Brake Booster and Vacuum Line Inspection

Locate the brake booster and check the vacuum line connected to it.
Examine the vacuum line for cracks or loose fittings; replace if necessary.
If performing a vacuum test, connect a hand-held vacuum pump to the booster to check for proper holding pressure.

4. Brake Booster Replacement (if necessary)

If the brake booster is faulty, disconnect the vacuum line and any electrical connectors.
Remove the mounting nuts or bolts securing the brake booster to the firewall.
Carefully pull the brake booster out from the engine bay and replace with a new unit.
Reinstall in reverse order, ensuring proper torque specifications for mounting hardware (typically around 10-15 ft-lbs).

5. Final Assembly

Reconnect the vacuum line and any electrical connectors.
Refill and bleed the brake system if necessary.
Reconnect the battery and check for proper operation.
