Brake bleed nipples

[Trev]

Hi,Just had to change a brake cylinder on the rear of my maverick as seals had gone & wanted to bleed the brakes all round but apon inspection the nipples have all been butchered so i would like to replace them with new ones.
Can anyone tell me what size i need?

Maverick 2.7 Lwb (94)

Thanks

I've recently changed the nipples on my Y61 Patrol and it was 8mm but could not say what is on a Maverick.
