Thread: det water fitting

does anyone know what size the banjo bolt is on a det for the water. im trying to replace it with a after market 4 an steel braid line and dont know how big the hole is what mm?

If I'm not mistaken it's the same as the brake calipers...I had the size and thread pitch in the common parts thread...but it seems to have disappeared.

I think 14mm I'll put my calipers on it when I get home as I'm in the middle of a rebuild.

It's 12mm

thanks
