On the Murena's everything concerning brakes is M10 x1.0 except for the rear calipers Banjo system.
The rear calipers on a Bagheera and a Murena are the same.
On the front you can also use Talbot Alpine and solara hoses.
Also some Peugeot 205 you can use.

205


I found on 1 Murena the Banjo bolt on the picture.
The hose M10x1.0 fits this banjo.
Been looking for this banjo's for some time.
Can't source them anywhere.
It would overhauling brakes on the rear more easy.
