Anyone else had this? Thought I’d maybe over-torqued it and/or somehow damaged an o-ring, but I’ve now replaced the o-rings and torqued to spec and it’s still leaking.
Tempted to try different hoses, but it seems a bit of a daft change if there’s a simple fix. “Just horse up the bolt” would be considered acceptable. I have a bag of o-rings to sacrifice now
Not had the banjo leaking before but managed to pop a piston out. Got it back in but wasn't right. Got in touch with Magura UK and they replaced FOC on their leak-proof warranty. Worth getting in touch, you might get a new brake.

Yeah, couldn't fix it. Assume it was some sort of tolerance thing between the banjo and caliper but switched to Shimano hose and I haven't died yet.

Funny you should say that. Just thought I’d try over-torquing it just for the craic. Went to 4Nm, didn’t budge - odd. Tried 5Nm, still nothing. Now wondering if the banjo bolt is actually bottoming in the hole.
Did you just use the Shimano hose with Magura banjo bolt?
We had one on the rear brake. Only option in the end was to fit a new hose.
Not ideal in the middle of a holiday so managed by topping up till we got home.

Your not the first person I’ve seen saying that - very odd that changing the hose/banjo completely can be the only fix

Can't remember which bolt I used, but I'd imagine either would be fine.
My theory was the o ring groove in the banjo was too deep and so the edge of the banjo bottomed out on the caliper before the o ring was properly compressed.
We used the genuine Magura hose and it seems to have cured it.
Not cheap and not something that should fail

Very possible, the o-rings barely clear the groove so good chance they aren’t seeing enough compression
I’ve happily used Uberbike in the past, so might just use them again to get away from what feels a bit like a lottery at the moment
Needed to reopen this one as I’m at my wits end with leaking banjos. Installed the brakes using the Magura hoses already installed. Both hoses leaked at the banjo, but front in particular.
Front - replaced the orings, torqued to spec, still leaking. Replaced with Shimano hose, though it was sorted but think there’s still a tiny leak between caliper and banjo.
Rear - thought it was fine then found a leak a few days ago. Decided to try the Uberbike hose kit that I’ve previously had success with - still leaking between caliper and banjo.
When I contacted Magura they were talking about a leak paths between layers of the hose. I’m not buying that one as there’s only one way for fluid into the banjo junction, if it was between layers it’d be coming out of the crimp and that’s dry.
Never had an issue like this in many, many years of working on my own brakes - think it was 1999 I got my first Hope.
Anyone got any thoughts before I launch these in the bin?i
How old are the brakes?
They’re new enough that sending back is an option. Although I’d be after warranty rather than return at this point I’d imagine due to the amount of messing around with them (they were for a Shigura setup)
The obvious answer is obvious 😉
Then sell the replacements!
That second part might be key. Got almost exactly 1 month until heading off to the Alps, so confidence in my brakes would be nice to have!
Magura have a 5 year no leak guarantee if you’re using their parts, I’d be going down that route to sort
