In the manual the br-505 caliper has a barrel adjuster. However the unit I received, doesn't. See the manual in step 3.

Is this a part that one can buy separately, should I contact shimano about it? Will they do anything about it. I've had the brake a few months before I installed it, so I can't take it back to the store
