Bought new in 2014. Pretty much trouble free, until.... I recently replace pads and rotors on all 4 wheels and I completely wore down my right rear pads in 3 weeks. I thought it might be a bad caliper so I replaced the right rear caliper last night and put new rear pads on both sides. Went for a test drive after dark and after about 30 miles I stoped and both rear rotors were glowing red. This morning I jacked up the back end and I can barely turn the rear wheels by hand. I also noticed last night that when I was going 40 mph or less that when I took my foot off the gas I would slow down to a stop like I was applying the brakes. Any thoughts?
