Noticed a slight weep from the rears on my fully re-built system today, so I put new nipples in and after an hour the joint between the head of the nipple and the brass banjo is looking damp again. am I looking at new banjo,s as well?
i must admit I,m a bit wary of overtightening them as I,ve them sheared off before now.

did you put new copper washers in both sides of the banjo and the right sizes.

i had that once on one of mine and it turned out to be the washer not sealing properly.

if u haven't got new u can refurb the originals by heating with a blowtorch or gas hob until glowing red then popping them in cold water.

but i would suggest thats the prob

this is a leak from the top of the 'turret' of the banjo,s between the banjo and the bleed nipple not the banjo to brake cylynder and brake line joints.

Maybe a cracked banjo, may be worth changing to see.

as Steve says, I always anneal the washers, but also 'face up' the banjo on an oilstone as I have found this to cause problems
sorry if i missed the point

No worries all points raised make me think!!

Are they correct thread bleed nipples ? These are the coarser threaded 3/8" BSF and not the more normal 3/8" UNF used at the front of the car.

Yep sent away especially for them, cost more in postage than parts, I,ve since nipped them up another eigth of a turn time will tell!

but be careful of these new bleed nipples, better to use new old stock or refurb existing
i have had a lot of probs with repro front nipples

Some of the machining on these 'new' brake parts can be pretty rough. If you remove the offending nipple (if it still leaks) you should be able to see 'witness' marks where it seats into the banjo. These marks should form a perfect smooth circle all the way round the nipple end.
