Osf Flexi To Banjo Connection

I'm having a pretty frustrating problem trying to bleed my brakes. What should be a simple thing is proving to be a nightmare.
The front banjo to flexi connection seeped pretty badly when I went to bleed the brakes so I replaced the banjo bolt with fresh copper washers.
I went to bleed them again and still leaked badly. So I tightened it up, retried, tightened, retried etc and even at the last try it still leaked. I tried so many times that I've now ended up snapping the banjo bolt in the Flexi.
I have no idea why it keeps leaking but I'm getting rather fed up of it now.
Anything I'm missing?

Did you anneal the copper washers before you fitted them?

No as that isn't something that should have to be done with a washer from Minispares.Did you anneal the copper washers before you fitted them?

Yeah you shouldnt have to mess with the washer when they are new. My only guess would be some corrosion on one of the faces or a hair line crack in the banjo.

Sometimes what you have to do is to double up on the copper washers on the brass 2 / 3 way union.
The thread inside the flexi hose is not deep enough sometimes to take the length of the banjo bolt
Adding 2 washers below the brass union, against the hose, then 2 washers against the head of the banjo.
This should solve your problem
The copper washers needed are 233220A and 3H550 if I remember rightly. The banjo is C5192A

As mentioned some flexi hoses are handed. Deep drilling for the banjo side and standard sorter drilling on the opposite side.
I would be checking the other side as well.
