They make noise...but the pads seem in good shape. But pulls hard on braking. Well....do you have aftermarket tires/wheels? There bad on the front end. You have have an idler/pittman arm that is worn causing the Mada to pull to the side. Or a tie rod. But the noise...is it the low pad indicator rubbing the disc? The low pad indicator is just a metal clip that will rub the disc when it gets low...makes a high pitch scream....you may not be able to hear it at higher speeds.

You need to inspect the caliper pistons on the right caliper. There have been some problems with the pistons cracking/chipping. This could cause the brake on that wheel to not release completely. Don't worry about a idler/pittman arm since there aren't any on the Armada. (rack and pinion steering don't use them)
This is a problem that need attention now. Correct it before it causes more damage. If you aren't confortable doing the work yourself take it to someone you trust. If it is piston failure it should still be covered under warranty..

whoops...that's right....mental lapse...forgot about the rack and pinion.... See....told ya SCR was the man!!!
