Making new brake lines

[Easy-X]

I've had a few goes at making up braided steel brake lines with AN-3 fittings and they've all gone pretty well so far. Gonna do the same for the old Triumph.

The front's pretty straightforward although we're probably going to drop the inline pressure switch and just go with an aftermarket lever/MC with and integral switch - so single line rather than in two parts.

The rear caliper has some weird twisty hard line attached to the bracket which seems a bit unnecessary.

(Bike's in bits so this is the best photo I found on the Interwebs, ignore the finger pointing "what's the torque spec for this bit?" hardline's circled in red.)

So from the master you have a little hose going to the hard line which is fixed to the caliper bracket and then the hard line snakes down to the bottom of the brake caliper.

I'm wondering why bother since I spotted this sort of arrangement:

What is the advantage of a hodge-podge of hard lines and flexible hoses? The front of my XSR is terrible for it...

Hard line prevents flex and expansion, I would have thought, thus increasing the efficiency of the hydraulic force being transmitted where it's needed.

I wonder why they used that S-shaped section of brake line though. Why would it be that long?

For the first pic, it looks like just an easier way of getting the hose around a tight bend without kinking the lines.

For the second pic, it's a way of allowing movement in the swingarm without putting tension on the line which is fixed to the "body" of the bike.
