I've had good success using the OEM brake rotors and Akebono pads on my GM vehicles. The vast majority of GM vehicles come from the factory with Akebono pads and rotors. I prefer the OEM rotors because they are designed to combat "lot rot" better than the average rotor and they seem to be heavier as well. The pads I usually just get the Akebono ones because they are less expensive.
Keep in mind that the electronic rear parking brake on that Equinox must be put into service mode via the computer. Some cars require a scan tool, others have a sequence of pressing the parking brake button to retract the caliper. If you twist in the calipers without doing this, you are going to be buying new rear calipers.
