I thought I would stick this here rather then the Mondince 336 dedicated thread.
When I try and centre my front caliper I cant get it to point where the pads and disc is not rubbing.
New disc and new pads are the worst combo. Old disc and new pads is the best I can get but still get a 'ping'.
After about an hour of messing around I noticed that the bottom part of the caliper is being sitting inwards ie the bottom screw hole in the frame is not in line with the top hole.
Now if I pull the bracket at the bottom to make it level the pad makes contact with the inside of the disc evenly. As soon as I open the bottom nut to centre the caliper and pads the bottom jump inwards towards the inside of the frame making centreing impossible.
I wanted to ask here to see if its me before I touch base with Mondince about it!
In the picture maybe you can see how the bottom of the bracket is moving inwards.

I manage to get where it rolling without 'pinging'.
I had to open each bolt a fraction and adjust the top and bottom of the bracket seperatley to get clearance.
It was like having to make small pivots of the top and bottom without one interfering with the other.

new brake pad are not parallel each other.
Brand new rotor are always with some micro "chip" in the machining
I always suffer a little when using new brake pads so I try to aling as better as I can than...the downhill let the brake pads bed by themself
That's why professional teams and advanced shop use this bedding machine

+1 on the importance of bedding in these things. Perfection on the bike stand at day zero doesnt matter, the bike needs a fair bit of shake down before it's worth worrying about the slightest noise or misalignment. True for rotors, headsets, gears, pretty much everything, really.
