So as title says I wanted a 180mm on the rear ive fitted the adapter and new rotor but it just gets stuck on the brake as though the adapter im assuming is to small so im confused as to what ive done wrong. The adaspter ive fitted is the uberbike post to post 160mm to 180mm adapter.

Turn the adaptor around so the high mounting point is at the front. Make sure the longer caliper bolt of the two goes with it and screw that in at the front too.

What Reaperactual said is correct.

The 'UP' that's stamped on the adapter is only 'UP' if that adapter is attached to brake mounts on a fork or seat stay, if that adapter is attached to brake mounts on a chain stay the 'UP' needs to be 'DOWN'.

For your rear brake, the UP ^ symbol should be facing front.
