There are small rubber concertina boots at the caliper end of the handbrake cables on my Stilo 1.4 5 door. They have both perished and I wondered if they were difficult to replace.
Pretty common failing that. Doubt they're available as a separate replacement part. Better to just smother the ends of the cables with copper grease to keep the elements out...
Slacken the handbrake cable adjusting nut, then unhook the ends of the cable from the lever on the rear calipers. The adjuster is under a lift up panel in the carpet behind the middle of the front seats.
