If had to happen eventually... I had an OEM part wear out. The rear brake on the passenger side started groaning when applied a couple of days ago. I replaced the pads on both axles. The rear definitly needed changing, the front set was only about 1/2 worn, but went ahead and changed them anyway. FYI for those that don't know, the rear pads are about half the surface area as the front. I've never had a rear set wear out before a front set before, and apparently the size difference between pads is Hyundai's engineering method to have all the pads wear out at about the same time.

The change went very smoothly. It could be done in about two hours assuming your working in the driveway and have a floor jack and a jack stand for safety. The pads just pop out of place and the new ones pop in. A 14mm socket is used on the rear calipers, a 17mm socket on the front. Thankfully we haven't had a flat tire since the dealership didn't torque the wheels correctly the last time the tires were rotated... they set their air wrench on "KILL" instead of torquing them to specs.

I bought a set of Thermo Quiet pads made by Wagner upon recommendation from a co-worker who's wife works at an auto parts store. They are supposed to be relatively long lasting, relatively clean (little brake dust on the wheels) and relatively quiet. They didn't require any brake pad grease for installation, and though I've only driven 50 miles on them so far, they do have a little noise but that should go away pretty quick. I did not turn the rotors as they were practically smooth and I will probably just replace them at the next brake change.
