Rear Disk Brakes - help

[Hammy]

Just changed chain & sprockets, now rear disk brakes seem to be sticking. have checked alignment of wheel etc. Cannot find diagram of rear disk brakes for dommie anywhere.Seem to have pretty good pads on (recently purchased dommie after 8 years and 2 kids without wheels) Don't know where to start.

Hammy,
The caliper carrier fits into a grove on the swinging arm and in my experience it is possible you may not located this correctly and it can cause the caliper to bind.
Just check the carrier is free to move it should be possible to rattle it.
If everthing looks ok maybe the caliper piston is sticking. Remove the caliper and push the pads back (can be done insitu) and then pump them back onto the disc.

Another thing to check is left and right wheel spacers are in the right sides.

(once installed the wrong way on a transalp, threw the wheel off centre a couple of mm)
