:plus1:for DIY. I am a huge DIY advocate, as I believe in building a relationship between man and machine. Calipers are a good starting point, as they are pretty easy. (Though I am a former hydraulic mech, and used to them.) So long as you don't have any significant corrosion in the cylinder wall that would require honing, you can just scrub them up with some brake kleen and get a repack kit from your dealer or online. Be one with the bike and brakes, my friend!
