Sounds like brake issues. If you "do it yourself" make sure you look at both inboard and outboard pads. Some times the outboard pad, the one you see when you look through the wheel, may be ok, but the inboard pad is worn out and touching the rotor. Also if you "diy" make sure both caliper slide pins and bracket points are lubed w/brake caliper grease, and you will need a special brake tool to "screw in" the rear calipers. Most auto parts suppliers also carry a wide range of "loaner tools". If your brake pads have worn into the rotors, REPLACE them don't resurface them. This would also be a good time for any brake upgrades, cross drilled and slotted rotors and a set of ceramic pads
