Check flares on preformed lines!

Bought stainless steel brake lines for my Duster and after installing the passenger front to distribution block line (easily the hardest one while engine is installed), I found an issue. The double flare at the distribution block was not completed!!!!!! I am so frustrated by that... and if had still had headers on the car it would have been impossible to get the double flare tools in there with the car on a lift.... end of day not impressed with the Inline Tube lines..... sorry but used to like them until fighting an incomplete flare on the worst line to install in the worst location to deal with it... and still wont know if it doesn’t leak until I get the fluid in it....


Oh, and I bought one of those repop distribution/proportioning blocks and see a thread about those leaking so hoping I don’t have that problem next...
That sucks man.. Hopefully you don't have a faulty valve now.
What distribution/proportioning valve did you buy?
