This is a picture of how I routed my cables, I haven't got one of the brackets, but I made new ones on quite a tight angle to get them away from the bulkhead. I just bent some flat bar which I slotted for the cable, I also welded plates across the tight angle to give strength when the hand brake is pulled on. It works ok but only just went through the IVA, you need to set the caliper just right & get them bedded in, my examiner took my car into the car park & drove it round with the hand brake on to get some heat into them! They passed. You are allowed a little drag on the brakes! It's well worth having a bit of drag on them. There is an adjustment screw on the inside face of the caliper, you need to use these to get the piston sitting in the right place. Hope this helps.
