Leaking banjo bolts

[Hotrodbob]

Hi All
I am having a torrid time with the banjo bolts leaking in the front (kit supplied ) calipers. A lot on the drivers side and a bit on the passenger side.

I am scarred to tighten the bolts any more as I have already used a lot of torque to get them to this point and I am worried that I will cause damage if I go tighter.

Has anyone else had the same thing or could somebody give me some advice as to how to resolve the leaking.

Thanks
Rob

Mine leaked a bit also. I backed them off a bit and re-tightened.

Have you got the copper washers on both sides of the hose fitting? Also you can try heating the copper washers till they are cherry red and then drop them into water this will remove any hardening, and they seal better i've done this before with good results, another suggestion is to heat up new washers before installing them so they seal better. Copper can harden when subjected to vibration. I think the term is annealing but i can't remember if that refers to the hardening or the softening process. Hope this helps.

Stat-o-seals will fix you up (just like I posted in the other thread referenced above)

FFR does not supply copper crush washers. They supply aluminum ones. At least on the last 2 kits that I have built. I make a trip to the auto parts store and buy 10mm copper crush washers.

OEM copper crush washers are thick, soft, and have ridges in them. Aftermarket parts house washers are hard, thin, and flat. I have gone so far as to reuse OEM washers simply because they would seal up when the ones provided with hoses, etc., wouldn't.

It may not be the washer...Factory Five apparently had a batch of reject front brake lines in 2012. I tried everything until I noticed the "score" marks on the fitting. If your look like the image below, call and they will replace.17574

Yeah, that would be hard for anything to seal against...

After I sent FFR those photos they immediately sent me new front brake lines. Those were perfectly smooth and worked fine first try. It seems like the copper washers would always be better than hard aluminum, but don't waste time trying to bandaid this. If you see any king of machining mark on the fitting, call FFR and get them replaced. If you read all the past posts regarding this, their supplier obviously has intermitent quality problems (China?).

good point for anyone dealing with problems like this stop what your doing and start looking,just like Tcollins said,no bandaid fix,exchange or replace,if you don't normally work on cars,the feel method can be bad to your health and wallet,you a good torque wrench.
