Morning, could someone please tell me the size of the bleed nipple on the front caliper.

Cheers

I think those are m7 with an 8mm hexagon--DO NOT try and undo one that has been in there for a long time without warming the caliper housing and also use a long socket with a T bar so you don't put uneven stress on the thread

Yep, you can't be careful enough.

If you have to buy new bleed nipples, buy those for a CB250N Super Dream as they're a 10mm hex with the same size threaded part.
