I want to replace either just the end if possible or the entire braided brake line on this BBK as it has corrosion. But I don't know the size of the hex which screws into the caliper. How can I figure this out? It's a VVTR BBK
Remove it, measure the outside diameter and thread pitch, look up the standard threads matching that - in most cases there will only be one possibility.
Thank you, hopefully, it will be obtainable. The BBK is discontinued and from Taiwan, so fingers crossed.
