Issues, Solutions and Brake system

So last time you remember I fitted the steering rack and had an issue on fowling the brake pedal, well the manual rack and longer column does appear to resolve this. I now need to fit this permanently and get the column attached permanently as well.(that will be a future update)

So in the meantime I have been putting the front suspension corners together. This showed up an issue with the steering rack as it was pulling both wheels inwards, after speaking with DDR I need different / longer tie rod ends so am awaiting the details on them for the time being but at least that mean't I could move on and not worry about the issue.

The next area for me is to fit the brake lines, however because of the tunnel under the car being large but still tight to carry the coolant pipes I needed to do a dry fit of both at the same time. So in the tunnel I will mount the rear brake and clutch lines at the top of the tunnel and the coolant pipes underneath. I am using brake line clips that you simply drill a 6mm hole for and push the clip in, they are far more secure then I thought they would be and will also pass the IVA test.

The IVA states it has to be secure and as there are no bends in this area, there should be no movement, the extra support will be on either end where the pipe bends. My first issue was...I cant get a drill up there...So I had to drill through the very substantial steel frame  from inside the cabin...then drill back out the front side. I will have to grommet the holes in the cabin which wont be seen when the interior is done, but I had no other solution as a right angle drill wouldn't even fit up there.

This weekend Ill be making up the initial pipes for the clutch and brake line down the tunnel and then hopefully rivnut'ing below for some P clips to hold the coolant pipes. I've decided I will run the Power cable, wiring loom, aircon pipes, earth down inside the cabin, most will go down the centre of the cabin under the centre console as there is plenty of room. I will separate the positive cable's run point from the loom / earth to ensure no electrical issues are caused.

Finally in the final prep for the brake line creation / positioning, I fitted together the front suspension and brakes. They are 324mm Supra MkIV vented front discs with 4 pot Nissan front callipers (used on Sx200 / Skyline GTR) with an adapter bracket and stainless steel flexible brake line (PVC covered - required for IVA test)
