If you have the 'standard' Shimano 105/Ultegra 'brifters' for your brake/shift levers (on your Madone?), it is non normal to accept to unscrew anything at the brifter end to change either a brake or shift cable.
Just release the cable at the derailleur or brake end, cutting the niggling thingy off the stop of the cable that keeps it from fraying and so it can exist pulled out through the housing. For a derailleur cable, shift the gears to the pocket-size ring on the forepart and the smallest cog on the back to release any tension in the shift cables before loosening the derailleur stop, and to position the shifter cable stop in the proper location to pull it out of the shifter.
And then, for a restriction cable, pull the lever towards the handle bar similar you would if putting on the brake. Information technology should move very hands all the way to the bar. I concur it there with a 'rubber ring' made by cutting an one-time inner tube cross-wise in a thin width. Then push button the inner brake cable out of the restriction lever...it should just come out of the brake lever far enough to catch it with your fingers, or a pair of needle nose pliers. Pull it all the way out.
If you are going to supervene upon the derailleur cables, earlier re-attaching the brake cables, while the brake lever is slack, against the handlebars, push the derailleur cablevision out of the shifter lever. This volition only piece of work if the shifter was in the slackest cable �gear� before you loosened the derailleur cablevision, otherwise the piddling hole in the shifter lever will be blocked and the cable head won�t come out. It is possible to pull the slack out of the shifter cable by hand while shifting the modest shift levers to the inner-nigh �clicks� to go the cablevision hole to line upward. Afterwards the derailleur cable has been pulled out, a new one can be pushed in through the pocket-sized hole in the side of the shifter lever, feed under the bottom bracket, and routed to the respective derailleur, and afterwards re-attached and adapted.
While the brake levers are slack, against the handlebars, the new restriction cables can feed into the pigsty for them in the brake lever, out the two front cablevision housings and routed on to the respective brake caliper, re-attached and adjusted. This is probably the hardest part, as they ever seem to hang up when trying to push them through the shifter housing and into the cable housing burried under the handlebar tape.
If my explanation makes no sense, check the Shimano Tech Documents web site for your model of shift/brake levers:
