Rear Brake Hard Line into Flexi

[McSwerve]

Trying to replace one of the rear hard lines (chassis to calliper), and for the life of me I can’t get the new line back into the old Flexi.
Just doesn’t want to bite.
I’m guessing the old Flexi thread is corroded, so should probably be fitting a new one at the same time.
Thoughts??
Also for the rear is it worth a braided Flexi upgrade??

Its worth it on the basis that your flexi lines will be well past it by now.

You can purchase a kit which replaces the whole lot with flexi inc the stupid short ones between body and beam. It made no negative difference to mine but I doubt rear braided lines would be an improvement over healthy oem rears.

Done. Much easier with new Flexi and bending the clips back a bit. Cheers
