D2 rear pads not making full contact

Hi all my rear pads arnt sitting right just replaced discs and pads on the rear of a d2 as the pads were on the limit.Give everything a good clean new sliding pins on each side everything went back as it should.I done this before taking my caravan away.And they are wearing exactly the same the fronts are fine I done them not so long ago.Any ideas or help would be appreciated going have them apart today for further investigation.

When you say they aren't sitting right what do you mean? With the caliper off and the pads in place are they touching the disc? Are they also a good fit in the carrier?
