fitting rear brake pipes
 

Please can any one help me with fitting instruction and any pictures if possible on rear brake pipes?
MOT failure rear metal brake pipes corroded where they go into the flexible pipes.
Do I have to drop the rear suspension to get the brake pipes from front to back?
Is it worth doing all of the metal pipes in one go.
Bleeding the system
Worked on braking systems but never on a Subee
Cheers
