Ok, so I finished the install on front and rear wilwood brake kit and filled up brake fluid reservoir and noticed all the supplied fittings from wilwood that connect to factory brake lines are leaking. I have tried swapping them around but they still leak has anyone had this problem or is it just my bad luck?

Thats strange. Which connections? A link to the kit or photos might help.

In my experience it is realllllly easy to cross thread brake fittings, but also learned that even the slightest variation in the cone even though the are the same thread pitch can cause a leak. Definetly verify with Wilwood you got the correct ones. There is almost no discernable visual difference.

Installed the brake kit on front and rear but the fittings they provided for the brake line (factory hard line to steel braided line) are all leaking. I have tried swapping them around from front to back and still leaking even called wilwood and sent them pictures of the fittings to make sure they were the right ones (they said yes). Has anyone had issues like this or is it just me, any suggestions or advise?

I would take pictures of the fittings and send them to wild-wood or contact the vendor you purchased them from and see if they can offer some support!

Those fittings should have thread tape on them.

Shouldnt use thread tape on brake lines since brake fluid will dissolve the tape and youre back at square one. The flares on the fittings are what does the sealing. I would say they arent mating up properly. Ive used wilwood lines before on other cars and when i made a brake set for my last car and they worked perfectly. Maybe just got a bad set.

I only say that because of this video. I thought the same thing. Check out 2:04 in this vid.

Fwiw I've done more than a couple brake caliper upgrades, and this was the first time I've seen someone use thread tape.
And yes, the flares in the ends should eliminate any need for thread tape.

How about that. Ive watched that video multiple times and never noticed him doing that. Still dont know if id trust that though.

No thread tape on flare fittings. If you did it could possibly contaminate the fluid and block passage. Could be the wrong fittings JIC vs SAE. Same thread different cone.

Just watched the video again and caught it and remembered this as well but still didnt use it on mine without issue. The fitting going into the caliper is considered a pipe fitting. If you look at it, its isnt a flared end like the other end or rest of the brake lines. Still kind of iffy with it being used.

Merged the threads.

You are correct the fitting going into the caliper is NPT which is taper thread where normally you would use tape ie water, gas, but the brake fittings are brass so they deform properly without the use of tape or dope. Similar to the copper wahers you would use one the banjo bolt. If you line are leaking, they either cross threaded which is very easy to do, or the have the wrong cone (taper) even though they thread in no problem.

By removing and re-installing, then removing and re-installing, you've work hardened and possibly galled or split the lines.

Yeah, forgot! still having problem with leaks even though wilwood says the fittings are the right ones. Put the original brake lines on and have no leaks (imagine that). To bad the original lines do not fit wilwood calipers.

Can also shoot roadrace an email or call and see what they say. They sell the wilwood kits along with their own lines for stock calipers. They may have some insight into the fittings.

Almost sounds like Willwood gave you the wrong fittings.

Have been having a bear of a time installing the brake lines... For anyone that's installed the brake lines, was there a lip at the end of the brake line fitting that prevents you of easily removing and installing a new brake line? When I was taking off the OEM brake line, I was spinning the line for hours until I realized that it was just spinning but not moving. Unlike the Wilwood video where the original brake line just came off easily (I also couldn't unscrew it with my hands like he could).

Eventually I had to use leverage to get it out. Now I'm trying to force the new brake line onto the fitting and it won't go on, guessing I just need two pliers to force it back on there. In any case, the installation process is not as easy as the Wilwood video looks....
