400 is a lot of labor money. I've not ran my system dry, but did complexly change the fluid. Its not any different than dealing with any other system.
Changing lines is easy but dirty. The brake fluid will eat the paint on your bike, so be advised. The secret is not to tighten the lines up when they are dry. If you do, there is so much air in the lines the mc wont push it all out.
I start by removing the lines I am going to change, being very careful with the dripping fluid. Place the new lines, with new crush washers into position, but dont fully tighten them. You then fill the master cylinder, pump it gently, and tighten the next fitting in the system once fluid starts dripping out. You can also get a Mity Vac
http://www.mityvac.com/pages/products_bcbe.aspThis makes the job simple as it will allow you to suck the air and fluid out of the bottom on the caliper while the lines are tight...no mess. I've never bothered to get one, but they rock.
ABS systems can be tough to bleed if they have hidden reservoirs, but I dont think the c14 does. Unless I am missing something, 400 sounds leke its about twice what the cost should be.
