I believe this setup was copied off the factory 1968 Hemi Darts and Barracudas. You couldn't remove the drivers side valve cover without removing the master cylinder, so they used flexible hoses similar to this setup. You could move the master out of the way without disconnecting the brake lines. When you reinstalled the valve cover and the master cylinder, you would not need to bleed the brakes. I think they just used factory front brake hoses on the 1968 hemi cars.
