[c1800]

“ I think I need to properly research and make sure it's all connected correctly in that case.”

I went through the same exercise of doubt. Referred to the illustrations in the Haynes manual/Green book to determine the correct orientation of the hoses and lines. 142 Guy’s experience of his 140 configuration matches up with mine on my ‘71 1800E.

After I replaced all the calipers and hoses, I gave it a very hard pedal push test (while stationary in the garage) to ensure all was right, and a steel brake line in the front burst! My 1800 had previously sat for years and the line was corroded through, not sure if from inside or outside the line, but probably both.

On to phase 2, I replaced all the hard lines with cupronickel, learned how to flare brake lines. Mostly used the old fittings, as pointed out by 142, there’s different fittings and not readily available.
