Replacing pads on a honda is very, very easy. I have rear drums on my civic, so i can only say how to change the front pads since i doubt that is any different on your cr-v. With the wheel off and staring at the brakes, all you really do is remove the lower caliper bolt, swing the caliper up out of the way, and take both pads out. I like to replace the shims and clips every time i do the pads, which you can get at honda. The shims are pieces of metal which go on the back of the pads, some pads include these. The clips are the thin pieces of metal that hold the pads in the caliper, you should see what i'm talking about when you get there. Then you just rub a layer of anti-squeal grease on the back of the pads, which make contact with the caliper pistons, and put the pads in. swing caliper down, bolt everything back togeather, and you're all set. If you decide to do it yourself, i can scan the pages out of my chiltons for you.
