The pieces I listed are to completely remove the parking brake ...including the cable operated portions at the caliper and the "brick " on the clutch perch, the actual switch in the perch is quite small and can be just removed, but that still leaves the large part the cable connects to, or the "brick " as you call it. The only solution to that is a new perch/lever.
Just unhooking the switch/wires does not completly solve your problem as my first post does.
