Hi many thanks for this, I cant get the pads in with the spring but when trying without the spring it’s so much easier I can’t get them down far enough. With spring on I mean I’m only trying with the old pads until new ones arrive, so I will remove those 2 in green as they won’t be there for no reason. It will make it much easier as new pads will be much thicker, but I think those 2 nuts in green have some thread glue on them so will have to use brute force on those. I have some thread glue so will put some back when I tighten that plateyes, the one marked in yellow is the adjuster scre. It moves the fixed pad closer to and further away from the disc. You need it as close as possible without touching.
You can remove those two screws if you can to get the pads in if you have to.
There's a bit of a knack to getting the pads in. Try inserting the fixed one first, and make sure it's fully seated in position before dropping in the other one. You can screw the adjuster back a bit to get more room.
