Saw a car that had bolts holding the pads in the calipers. Why would you want to do this? I see that the bolts and nuts would be more secure in a way but the pins are held in with the keeper. Is this a racing thing?
Are you talking about the caliper bridge bolt? It's not there to hold the pads in, it is there to stop the caliper from spreading under pressure.
I do not know the term "caliper bridge bolt". The two retaining pins in the hardware mounting kits were replaced by bolts and nuts. See item # 15 in this diagram
