gabzor, all models have 2 brake pads on each wheel ... one brake pad on each side of the rotor. Apply the anti-squeal paste to the back of the brake pad that contacts the caliper piston. Refrain from using anti-seize paste on the brake system components. But first, contact the shop that installed the new brake pads and discuss the brake squeal with them. A reputable shop will guarantee their work and make sure things are right.

Realize that the process of removing the brake pads is easier if you remove the wear sensor(s). It's possible that you can remove/reinstall the wear sensor(s), but more than likely you will damage the existing wear sensors and need to install new ones. So have new wear sensors on hand before you start the job.
