ok so i dont have any pic but its a pretty simple part. its on the brembo front caliper. its the metal hose/line that screws right into the back of caliper itself. and anyone know where i can get a replacement one?

 

I would go to a hydraulics repair shop - I'm sure they could fab one up for you if you had an example or sketch w/measurements...powder coating sold seperately

 

i was looking at brake lines and i noticed 2 different kind. one where the line connects to this box thingy. front and back calipers. and one where you use banjo nut to connect them. whats the difference between them?
