Hello I will help you with your question,
Yes the pads have a "noisemaker" attached that should contact the brake rotor before the friction material is completely worn out.
You can drive it safely but get the brakes inspected as soon as possible.
Please let me know how I can help you with this
So there's no reason to think that this could be something else that would be an immediate safety issue?
As long as you are only hearing it when you apply the brakes and it is a light scraping it should be the warning that the pads are low. If it is a heavy grinding or happens without applying the brakes then there is reason to be concerned.
Please let me know how I can help
