Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the negative battery terminal to ensure safety.

2. Check Brake Fluid

Remove the master cylinder cap and inspect the brake fluid level.
If low, top off with the manufacturer-recommended brake fluid type (e.g., DOT 4).
Inspect the fluid for contamination; if contaminated, proceed to flush the brake system.

3. Inspect Brake Booster

Locate the brake booster connected to the master cylinder.
Check for vacuum leaks by applying a soapy water solution around the booster and listening for hissing sounds.
If leaks are found or if the booster is damaged, remove the brake booster:
- Detach the vacuum hose from the booster.
- Unbolt the booster from the firewall (usually requires a socket set).
- Carefully remove the booster, noting the orientation for reinstallation.

4. Replace Brake Booster (if necessary)

Install the new brake booster in reverse order of removal.
Ensure all connections are secure and vacuum hose is reattached properly.

5. Final Checks

Reconnect the battery terminal.
Test the brake pedal by pressing it several times to check for proper feel and responsiveness.
If the pedal feels normal, proceed to road test the vehicle.
