Fluid now changed. Think the problem has been found.
The near side old/ original calliper showed greater wear on the inboard pad than outboard. Off side calliper the pads had even wear. All 4 pads had a small “lip” on the outer edges as is normal & now chamfered off. Whilst there was no rubbing as such it was apparent that the in board pad near side was stiffer to move away from the disc compared to the outboard pad.
Methinks that the inboard pad has been slow to ease back, hence the extra wear. In the wet this possibly causes the near side disk to be a little warmer & so slightly dryer than the offside.
Guess time will tell as all sorted now.
Considering the problems I had with the off side calliper, hence the replacement ( subject of another thread) I think the callipers tolerances are a bit hit & miss if you are unlucky.
