TB/WP/Valve 03 – Brake Line issue

While preparing the car to drain the coolant, I noticed that the brake line at the rear was very close to the sway (anti-roll) bar even at the full droop position.
So, although it's going to slow me down, decided to put the tyres back on again and bounced the car a few times to settle the suspension and looked at the brake lines.
This photo is from the Rear Right and the car is sitting on the ground without any load.
This is too close because if you apply any load (i.e. going through the corner, luggage, body weight, etc), it will touch the sway bar.
In fact at the Rear Left, there was a clear scuff marking on both the sway bar and the brake line.
Just in case, I also looked at the Front and this side was even worse.
The Front Right was scuffing against the body work regardless of the full droop or no load condition.
I measured the brake line length from the edge of the fitting where it was connected to the brake pipe on the chassis to the centre of the fitting hole where the banjo bolt went through at the calliper body.
It was approximately at about 660mm at the Front and 590mm at the Rear.
These figures are way too long….
I normally ask Goodridge in Exeter to build the custom length brake line for me.
Based on the information supplied from the member ‘havoc’, we normally deal with the 'length' using the ‘hose cut length’ without the fittings.
So, above figures can't be directly compared to the ones that I use when placing an order but looked to me, they were more than 50mm longer.
The brake line looked to be twisted as well.
This is not the first time to see the issue with the installation of the brake line because about 10 days ago, I saw another NSX with heavily twisted brake line.
Looking at the state of the brake disc, pad and the brake line, it seemed that these were replaced quite recently.
The brake lines were custom made by someone using the parts from HEL so it would be best for the owner to take this NSX back to the shop and have them corrected.
Also, I noticed that the cable from the Rear bank sedondary O2 sensor was not secured or not routed properly.
It was scratching against the edge of the bracket and nearly cutting through the heat resistant sleeve.
Will re-route the cable.
I'll carry on with my TB service.....
