Update: I took the old brake line up to the garage, but they were totally perplexed by the fittings (not a good sign).
On examining the flare ends, I decided I was perplexed, too! Both flares appear to be double flares (I was expecting bubble flares). Indeed, the replacement rear brake line hoses I received from Dent look like they expect double flare connectors. Weren't the Europa S2 originals bubble flares?
So then I looked at the two lines at the front of the car, that attach to the master cylinder. They look to be bubble flares, as expected.
Now, I have another problem: my MC is a Cardone replacement, with M10x1.25 openings for what I believe is a double flared pipe, or is it ISO?! This means that I will need to replace the flares on the MC ends of the front lines so that they fit in the Cardone.
I ordered the OTC 4503 double flare kit, and some steel 3/16" brake line. When it arrived I started to practice making flares. Much harder than I expected to get the flare centered on the bore. Any tips most welcome!
Could someone put me out of my flare confusion misery? Do I need to buy the OTC 4504 (bubble flare) kit too?
Thanks!
