Help im pulling my hair out!

Can any one help me ive recently restored a 1991 vespa cosa 200 , ive just about finished but cant find the brake pipe that goes into the brake cylinder on the back hub.

I think its a hydraulic pipe but not sure ive tried everywhere and  even sip has not gone one in its catalogue, it comes through the frame and theres a small elbow on it that attatches to the brake cylinder,

Any help would be appreciated.

hi ...

 

normaly you should find something !?!

the brake system is ahydraulic system, so please look only for hydraulic pipes !

you got one main brake zylinder and 2 externals front and rear connected with the pipes

 

good luck

Cheers for your help
