Yes they would. Now, mind you, I don't know for SURE that this is what the car uses. It could have some odd ball bolt that needs a special tool. Earlier Malibus for instance used a clip to hold the wheel cyl in and it is a pain in the ars without a special tool designed JUST for this.
It could also be a female torx, so get over to the Sears store and look at what they have to see if it makes sense.
