The install is really easy. It is the bleeding that can be a problem. It is very cramped in the bleeder screw location and very hard to accurately control the opening and closing of the bleeding screw. I ended up with a lot of air in my system and it took me quite a while to bleed it all out.
I would recommend using this method to bleed the brakes.
