Perhaps some kind person here can help.
Trying to discover what thread is used on some hydraulic brake fastenings.
It is for the pipe union that goes into the brake lever on a motorbike. The union has a blind hole through it with another to the side so the fluid can pass from the piston into the banjo coupling and off down the pipe to the brake cylinder. It looks to be around the 3/8 inch BSF but when measured is 10 thou over size. Trying with my thread gaufes I can not tell if 20 TPI or 1.25 mm pitch.
Would anyone recognise what I am talking about and what is the actual thread used on these?
Also this is off a Jap motorbike a Honda superdream 250. Is it the same thread form used in the unions with cars with the copper or steel brake pipes?
trying to use parts from a breakers on a gokart brake system and would like to have copper pipes that I can bend.
