I've lost count the number of times I've had to remake brake lines after designs have changed, and here we go again...
I firstly 3D printed and assembled a plastic version of the commerically available hand-held straightener and it works surprisingly well especially compared to the DIY version I made years ago


The passenger side brake caliper line mount under the engine is far lower than ideal and exposes it to getting damaged from underneath.

I mocked up the brake line route with some wire and made a guard / skid plate that bolts to the tie-rod bracket, to mitigate any debris strike. The route does ensure clearance for the tie rod to fit and move up/down.

An intermediate line from underneath the gearbox to a joiner in the engine bay, with a mount against the subframe to hold the brake line joiner.

At the end of this intermediate line, I used a standard joiner however I machined a small section in the centre of it and 3D printed a saddle clamp for it, where the clamp has semi-circle underneath. This acts as a retainer and keeps the joiner from moving laterally, although thinking about it later this is probably overkill. Ah well

Now that I'm no longer using a brake booster, the brake line from the master cylinder to the front 3-way splitter Tee was remade (and Tee relocated from the previous location) and then the two lines from the splitter tee to the brake hose mounts made - a short line on the drivers side and longer one on the passenger side.

I also decided to remake the rear brake line (lower on on master cylinder) - so the bend radiuses matched
