This is a carbon fiber handbrake assembly like the one found on the World Rally Car from 1999-2006.  The mold for the handbrake lever was taken from the original Prodrive WRC car part. Part is made of 4x4 twill carbon fiber like the original.  Bracket is stainless steel, and includes an aluminum cam to hold the brake in the engaged position (like a makeshift parking brake).  Also included is a provision for a switch which disengages when the handbrake is pulled back.  This disengages the center diff (on cars equipped with DCCD), saving your center diff from frying.  The master cylinder is not included and has to be matched with whatever rear calipers you are using.
