Hello All
Looking to install the RAYBESTOS MC39087 Brake Master Cylinder, it has the 11/16 bore and dual system.

I don't have any hard brake lines to copy, so I'm making from scratch.

The terminations are M10 x1mm but what type of ends should it be, bubble, single flare of double flare?
Looking it to the socket I can see a small sealing flange or ledge rather than the conventional bubble fitting that show a smooth 45 degree slope

Any help welcome

Cheers

Dov
