    Hello, first post here. My 91 VFR hasn't leaked a drop of anything in the garage for the few months that I've owned it, but the yesterday in 70degree storage I noticed a puddle near the front tire and an orange drip hanging off the caliper. It seems the lower rubber line is failing somewhere near the crimp. There are no marks on the flare nuts so I'm assuming they are the original rubber lines. Does anyone have any opinions on if I should upgrade to stainless braided lines or stick to factory rubber? And which brand of stainless lines did you go with?

    I have steel braided lines on all my bikes, I just prefer them to the OEM rubber lines. It gives a nicer look along with some benefits. Long story short, regardless of what you choose to buy, you definitely need to replace at least the one weeping line. I went with HEL line kits for both my 5 and 6 Gens but there are several other makers out there, Galfer, Goodrich, Spiegler, just to name a few. There is one other place that has been mentioned that does custom lines for a good price, they're called Core Moto, perhaps check them out, they may even have a kit for your bike.

    Thanks, and yeah I'm definitely fixing it before riding. I'm glad I found this problem while it was in storage and not out on the road.

    sure it's not a leaky fork seal ?

    fork oil is usually ATF, and that's reddish in color.

    I took a look at it earlier today and there was another drop hanging from the caliper and I followed the drip trail up to where the hardline bracket attaches to the fork. I couldn't tell for sure if it was the fork seal or brake line so I removed the fender, cleaned everything well and have the line dangling away from the fork so I should know for sure in a day or two to see if the fork tube has a new wet spot or if the brake line does. But if you say the fork oil is probably ATF that makes me more certain that it's brake fluid by the smell and feel, plus there is a bubble in the sight glass that wasn't there before.

    Turns out it was the right fork seal leaking, so I'll be adding that to the spring time to do list.

    after the fork seals are replaced I would still do a brake flush on both rear and front and a clutch flush as well

    you'll also need to clean the rotor and caliper of any oil and replace the brake pads if they've been soaked.
