how to retain / restrain brake flexies.
At full lock, and a little before, my brake flexies foul on a part of my wishbones / swing arms (a 3 wheeler, not a locost). I made the steering
wrong and mounted the flexies to suit the old steering. The steering is right now but the hoses touch towards full lock.
The problem is that I can't find a good place to locate the fixed ends of the flexies that will allow them to reach the wheel at all points of
steering and suspension movement and not touch anything.
At full droop at full lock turned out, the flexies are almost straight. At full lock turned in, the pipes don't curl up enough to stop the
fouling.
What SVA approved ways can I restrain the flexies so that their movement is restricted to where it can't touch things?

I twisted mine so that the loop it creates clears the obstacles....

The trick is to make a kind of pigtail twisty loopy shape which acts like a spring, but you need some slack to be able to do this - maybe you need
longer flexies.

From the Goodridge Tech Data
Wherever a hose assembly is used
in either a static or dynamic flexing
application, it is necessary to ensure
that the centre line bend radius is
not taken below the minimum bend
radius for the hose.
Hose assemblies should not be
installed in such a manner that a
torque loading is imposed, either
during installation, or in subsequent
use. Torque loading of the hose
creates stresses in the hose, which
can shorten the hose life, or cause
the hose to collapse.
Whilst assembling the second end
fitting, especially if it is a female
union type or fitting, it is necessary
to ensure that the final tightening
of the nut does not also rotate the
spigot, thus imposing the torque to
the hose.
In the case of reusable fittings the
hex on the body should be held with
a spanner to prevent rotation.
When the hose includes elbow
fittings at both ends, it is
important to ensure the correct
alignment of the elbows relative
to each other during hose
manufacture. It is important to
ensure that the hose is connected
the right way round when installed.
When the hose has an elbow at
one end and a straight fitting the
other end, always connect the
elbow end first, to prevent possible
mis-alignment.
In applications where the hose
undergoes dynamic flexing, it is
necessary to ensure that all bends
in the hose are in one plane.
A hose which is bent in two or
more planes and then flexed is
subject to torsional forces which
may damage the hose.
As I understand this it says, "Dont twist the brake line". Why don't you use tie wraps or other fixings to secure the line to the
wish bone, leaving it free at each end to accomodate the suspension and steering movements?
