Ok guys, I'm getting ready to install my rear MKIV TT Brake to go with my Arz front kit. I have everything already, at least I hope. Here's what I need to know. From Djonez's website, on his write-up, he mentions that the MKIII rear brake lines bolt right in. Based on that, I ordered some rear only braided lines from Techna, since the front kit already comes with its own lines. Our brake lines on the rear, does not use a banjo bolt like the MKIV does, it kind of bolts straight to the caliper (you will get a better idea with the pics below). Therefore the techna does bolt right in the MKIV caliper, the only thing i need to know from you guys, is whats the right way to seal the line to the caliper. Please see my presentation, as you will understand my question better.
This is the Techna line fitting, next to the MKIV banjo bolt with copper washers.

As you can see, the techna line bolts right in the MKIV caliper, but leaves a gap than can be eliminated only by a washer as thick as the 2 copper washers. Keep in mind, that this is hand tight, but I dont think it will go much further.
Lastly, a picture that shows the calipers' insides
Basically, I just need to know, whats the best way to make sure it does'nt leak, more importantly, that it works. Do I find a copper washer thats thick enough? Is it good practice to use 2 washers like the picture shows? (no flame please) Teflon tape? It does not look like those fittings that will just seal as they get tighter, I might be wrong though.
I didn't go with MKIV lines, because apparently they are a little shorter than our brake lines and since it was mentioned that our brake lines work, I just upgraded my lines.
Thanks
