Brake Caliper - Hardware vs. Mounting Bracket?
 

I need to replace both front calipers and I also need new retaining pins. O-Reilly has them listed for $35.99 each with hardware, but without mounting bracket. They also have one listed with no price, also with hardware, but also with mounting bracket.

Does anyone have any idea what is typically referred to as hardware, or what the mounting bracket is exactly? Should I expect the retaining pins in the hardware?
