Well we all know that there are plenty of different brake upgrades for our Datsuns.

With those who have upgraded to using braided lines how many of you still use the steel pipe between the front strut and the calliper? If so why?

Is it to use the original retaining point on the strut? RTA or engineering reasons?

Why not use a retainer like on the link below and continue the braided line to the calliper and use a fitting to suit your calliper?

If you have done it this way, how have you done it and why?

Interested to read your opinions.

The reason we use a fixed line from the front calipers to the strut is for
safety reasons.
The bracket on the strut keeps the line in position as the strut
travels through bump & rebound.
Also more important it keeps the flex line in position as
the strut rotates when turning.
Less chance of things getting tangled up & the flex line rubbing on
the strut tube.
Its neater too IMHO.

Thanks Baz

I've made my own retainer bracket off the the original mounting point to run the braided line all the way thru to the calliper.

For me its one less join in the system that can play up and less chance of a solid line beening damaged while racing or kinked when the calliper is off the strut and being worked on.

Is there any concern about RTA laws or engineering for you changing the original method?

Rally car application, run a full braid from a bulkhead on the inner guard direct to the caliper. Planning on doing something similar for my 'club' car, though probably following the control arm. Though as Baz has mentioned, it's not an ideal situation due to the extra length of line to allow for suspension movement being able to get tangled around things. Also, we couldn't work out a way of having the line long enough without it rubbing on the bodywork, so in that spot it has a piece of cable tied fuel hose.

Remember, for a motorsport only application, use a line with compression fittings, rather than the crimp fittings that the ADR appr lines used.

When working out your routing of the lines, another thing to avoid is a twisting or torsional load on the line. Braided lines dont like this.

adr lines are now made with metal inserts and tested at 3000psi.
