Np 300 front suspension noise

[toyota boyz]

After my 10k service at massy my van have a glock sound when the brakes is applied. However massy said thats normal its the brakes booster. I never drove a vehicle where the brakes booster makes such a noise. Even going over speed bumps thw glock sound is there also. Any advise on how to remedy the problem
