Tektro Draco - Power loss and creak

Hi all,
I'm having a problem with a tektro draco hydraulic brake on the rear of my bike. Its not the greatest of brakes but has so far been dependable. I was out on a ride and it lost its stopping power, to the point where when the lever was fully depressed the wheel still turns but with a horrendous creak/squeal on/or around the rotor.
To try and sort it out I have since bled the brake which has made the lever much firmer, replaced the pads and cleaned the rotor with some alcohol rub. The stopping power is improved when riding but is still not what it was. If I engage the brake when stationary and just rock a bit of weight across the bike the creak is apparent, and I can get the wheel to turn. It's difficult to pinpoint the creak with a short arm and poor ear, but I think it could be from within the calliper.
Anybody got any ideas what could be causing this? I'm running short of ideas and am at the point of taking it to the LBS to see what they reckon.

I might take a look at servicing the caliper. Is this a fairly straight forward job of taking bolts out and making sure it all goes back in the same order?

I have the same brakes on my hardrock and had exactly the same problem. One day, on the way to work I realised back brake had lost all power. I took it to lbs and they adjusted some cetnralising thing and adjusted the reach and it fixed it. I was convinced it was a fault issue, dont start farking around with the calliper untill you know the problem!
