Anyone know the (internal) diameter of clear tubing I need to bleed a mini mono?

Ta.

bump for anyone who might be able to help with this (can’t measure brake)

ta.

6mm?

If the hose you have is slightly too small soak in boiling water and it gets much softer.

Pet shop for fish tank hose or car shop for screen wash hose.

Will depend on the age of the brake, recent ones(last year or two) require a much smaller bore.We’re currently using fuel tubing that the old man picked up at a model show, washer tubing/air line for fish tanks just falls off.

if you get one thats a bit tight – pop in some boiling water for 2 mins before hand, stretches on no worries – talking from experience!!

thanks all
hot water trick is a good one
