Pull the front wheels and look at the pad thickness. If the wear indicators are dragging replace the front pads. These are pretty easy to do and only require basic tools. For somebody that hasn't done this before, the hardest part will be pushing the caliper piston back into the caliper. They make special tools for doing this, and even though I have them I usually just use an old pad and a big pair of channel locks. A big "C" clamp would work as well.

Note: When you push the caliper piston back it will be pushing brake fluid backwards into your master cylinder reservoir. So, unless you use a Mity-Vac to remove fluid from the master 1st, or unless you crack the caliper bleeder nipples, it will most likely overflow the reservoir and make a mess. I prefer the Mity-Vac method as opening the bleeder nipples could possibly allow air into the system. Tim
