I consider it a weak link because now the entire brake line system in my truck is either rigid steel or flexible stainless, except for these 2 12" sections. So as the pressure builds, these 2 lines will swell because there is nowhere for the pressure to dissipate other than into the brake pads/calipers or swelling of the lines. I agree with you that it will not make that much of a difference, and I can definitely tell a difference in pedal stiffening since I have installed the lines, the only problem I have is not being told beforehand that there would still be 24" of rubber lines left when I bought this $200 brake line kit. I was under the impression that all of the lines would be replaced.
I noticed on your website this morning that a disclaimer has been added. That's all most customers expect.
I was on the fence posting this as SDHQ has been a great company to deal with, but I have to admit I agree with JROCK on this one. I spent the $200+ for the lines with the intention of getting rid of all the rubber lines on the truck. Granted, with a few fittings and a flaring tool that could still be accomplished, but I ran out of time (and patience).
Positive- even though there are still 2 12" rubber lines on the back end of the truck the brakes feel better. Not sure if this is because of the fresh fluid and bleeding or the 4 SS lines I was able to use, but the pedal is firmer and the brakes are "touchier" (in a good way).
Negative- I have two beautiful SDHQ lines sitting in my garage that I paid for and can't use right now.
I still have two rubber lines on my truck
Not really throwing stones in any direction as if it was that important to me I would get the right fittings and the flaring tool and modify the existing hard lines. What does bum me out is paying for something expecting a certain outcome, then not being able to use the product you paid for as expected.
What was the real bummer was thinking it was going to be a couple hour job, then destroying the right rear hard line trying to separate it from the attached flex line, then jumping through my ass trying to find a replacement in time to get the truck back up and functioning before I had to go back to work.
