front break line splice leakage

so first off i dont understand why there are 2 break lines per side (junction box to caliper). why have a splice in there for no reason. anyway installed my new line kit from cruisin image. the compression fittings where the lower lines connect toghether...there is leakage occuring. i tightened up both sides of the compression fitting and still a little leak. is there a tightening sequence on those splices or somthin?

i hope the dot 5 silicone brake fluid doesnt hurt paint like it says cause it went all over.

There should only be one brake line to each caliper. Dot 5 shouldn"t affect paint.

Try a little teflon tape on the compression fitting threads
There are probably 2 lines because originally the second line (to the caliper) was copper tubing. Too lazy to design a mew line when the change was made. Just add another line. If your wallet can handle it, change to braided stainless lines. No splices at all. Just use a double banjo bolt at the master cylinder. That's what I did on my dual caliper 550. Works great! I have pictures if you don't get it. Couldn't be easier.

thanks coyote. ya i was kinda thinking how overly complicated the brake system is. and im going ive got a leak here at this completely unnessesary compression fitting, awesome. lol. ya i thought about going to braided stainless we will see. i could just go junction box to calipers in braided?

I had the same problem using the same lines. I just eliminated the original compression fitting. If I remember correctly, I ended up only using 2 lines from the kit per caliper. Rather than 3 that Suzuki originally used. Yes, brake fluid will cause havoc on paint if it is not immediately and completely cleaned off that surface. If it has, have no fear. Always use something to protect surfaces when using it. Towel, rag, etc.

Teflon tape won't work, brake fluid or gasoline will turn it into a goo in a matter of days. Clogging lines or making it not effective. I found that out trying it on a petcock once. :mrgreen:

Did you find a way to stop the leak?

I tightened the compression fitting some more and seemed to fix it
