2007 Silverado Classic Brakes

[07Silverado4X4]

Guys, quick question a search didn't help me with. I have an 07 crew cab classic I need front brake pads for. Guy at Pep Boys says there are 2 different braking systems. My assumption was the 2 different body styles for 07 but he says no. Either way I have an 07 classic that came with 17" wheels, now it has 20". Any one know what kind of brake pads I will need? Thanks

I just checked Pep Boys Web site and they don't mention two braking systems, there were multiple choices for brands but that was it.
