Fluid leak after new brake lines.

Hello All, hope someone'll be able to offer me some advice.

Decided yesterday, that I was going to step up my bike maintenance skills and tackle the front brake - upgrading the lines to Goodridge stainless steel jobbies.

Everything was going fine until I tried to replace the fluid, when I noticed it was coming right back out at me, on the right hand side calliper.

I've tried tightening and retightening that sides bolts (think might have done so a tad too enthusiastically at one point), but still it leaks. To be clear, it is when I'm pumping the brake lever, that the fluid squirts right back out again.

Pretty sure only the right hand side is affected.

Any word of wisdom would be appreciated. This would be the second day of a 2 hour job and I'm beginning to lose the will to live.

Cheers

Have you remembered to put a washer on the banjo bolt?

If not check the banjo itself, I have seen one where there was a tiny hairline, presumably left over from the part being forged which allowed a leak.

Hey thanks, I was struggling and completely frustrated by the close of play yesterday, but I did try replacing the new stainless steel fitting that came with the set, with the original bolt to see whether the issue lay with the new bolt... no joy. And yes, there are two copper washers (I even tried adding back in one of the original washers - less is more, is something I struggle with)... all to no avail.

Look carefully where it is escaping, if it is coming from between fitting and washer then I suspect a dodgy fitting.

OK gonna give it another go.

Don't get p*ssed off and hammer the torque on the bolt and strip the caliper.. that will ruin your day.

really, really scared that I might've managed to do that already. Off to have a look .. I've procrastinated long enough.

cheers

worst case you'll need a new caliper. Dont worry about it.

Check the banjo fitting, and compare the angle of the fitting to the original banjo. I've seen this going from gsxr to sv callipers, where the fittings were fouling on the lip of the calliper

If God loves a trier, then I'm truly loved ... though without a moveable bike.

Bled the bike dry of fluid - not sure this was a good idea - and then set everything up again.

... and still the bike leaks ... but now in TWO places!!

However I did notice one thing, and though it's of no consequence to me now, it might help someone else who finds themselves here - though I appreciate, I'm a special type of numpty, so this'll probably have been obvious to just about anyone other than me. Anyhoo, the pack came with 3 curved banjoes and 1 straight one. The straight banjo is for the brake fluid reservoir. There should be a curved one right next to the reservoir, methinks, and then the straight one beside that. I, of course, hadn't noticed the difference in banjoes (???) and stuck it on the right calliper ... the one that was leaking initially!!

But none of this explains why both callipers now leak. Nothing more for it, I'm done for, gonna call in the big guns tomorrow.

Thanks for all the help. Think I'll stick to simpler jobs in the future ... frontend swap anybody??
