Make sure when you replace the spoke that you cinch that puppy down;be sure you hear a high "ting" when plucking! A loose spoke is commonly the reason for spokes braking. Make sure that all of your spokes have that high "ting" noise! Rid your wheel of any buzzards. Or another way to find out the tension of the spokes is to take two spokes at a time and grasp them with index and thumb and press inward. If you come across a spoke that gives more than the others, tighten it! Spokes loosen over time and require tightening every now and then.

While truing spokes I'll commonly tighten the side that needs to be pulled one way or the other without loosening any spokes. Not usually a method recommended in bike books. My bad!
