The rear ones to be precise.
Trying to remove them with out having to drill anything.

butt to get out when not kept on top of. Good luck. Lol

Try heat. On the caliper itself at the back of where the pins insert, that should expand the hole. But even heat direct on the pins might do it, might break the corrosion seal. When they're hot try getting a punch on the end and bang them in a bit more - I know it sounds Irish but the impact will break the corrosion and you can then wiggle them out with some grips.

Coppaslip when re-assembling, obviously

Ill try the heat thing but im worried about buggering the seals.

Ive tried the irish thing, i use the same method with seized bolts to free them up.
But this didnt work

If all else fails and you don't mind replacing the pins, cut a shallow slot across the pin near the free end. Put a screwdriver etc into the slot at a shallow angle and drift the pin out with a hammer and the screwey.

If all else fails, buy a used caliper from ebay that is the same colour as the 4pot nissins you have for the front
