as above

the bleed nipples on my wilwood 4 pots aseem to be 6.5mm and i have a socket for this size but would like an off set ring spanner to use for bleeding them as i cant keep a socket on there with the bleed tube at the same time

but there aint a spanner for 6.5mm? so do you think its more than likely a 1/4 spanner which is 6.35mm

 

the next resonable size up is 9/32

if this still doesnt fit you can always try and find a 17/64 but thats going to be difficult

 

I used to use 1/4 on my old superlites before i got rid of them

 

1/4, that's what my Wilwoods were.

 

i think 1/4 is 6.35mm

 

il go for 1/4 as it must be right
