Stupid disc brakes are driving me crazy

[R3awak3n]

You all might know that I was dissing on my TRP spyres and was about to go shimano hydro. I then decided to keep tweeking the spyres and wait till campagnolo releases their hydro version (seriously campy, you are now pissing me off).

Anyways, I was having problems with pull and campy levers but that is solved, I am getting a nice amount of travel, not much mush at all. Pretty happy with that. But now I am getting some bad shudder, only when I am going slow into stopping.

I have pretty much done anything, new pads, new rotor (went 180mm), even put a new caliper because I had one around. Re ajusted and still have this damn shudder. If I squeeze the brake hard it fees like the disc still moves around a tiny little bit. Its like it does not bite properly. I was hopping it would go away once the pads are fully bedded but does not seem like it.

The only thing that seems left to do is to face the mounts but when I first got the bike I did not have this problem and the pads look pretty straight with the rotor. I am out of ideas and it is driving me crazy
