Accessories set brembo brakes

Hello, since I found nothing on the internet I thought I was trying here. I drive a kia stinger gt 3.3 and soon the brakes are due because the guarantee is also as good as to end I decided to have the brakes made in a free workshop now to my question my workshop said to me that I should always also get the pins (bolts, accessories set) because you should only use them once and then make them new when braking, but suffer r I can’t find anything on the Internet, one of you may have an idea or even a link for front and rear axle. Thank you in advance
