Hi there
Can someone tell me what I need to join 3/16 brake line to 1/4?

Why have you got two sizes?

Rather join then the easy way is to use 3/16" pipe and a special 12m thread tube nut

see eBay item 230661454875

It's really for my clutch line. the focus slave cylinder is the 1/4 line and I am using a rav 4 master cylinder that has the 3/16 line and I need a in line joint, does anyone know the joint and where i can get it?

Only available in UNF threads you can probably find a female to female one on ebay but you would need UNF tube nuts and be able to flair 1/4" pipe.


If you get the M12 thread tube nut for 3/16" pipe off ebay it screws into the Focus cylinder job done !
