Bleeding Banjos

I've got a fluid leak from the Banjos on both my magura MT5 calipers. Levers are XT and hoses, calipers and O-rings are all Magura.

I've swapped calipers front to rear and cleaned everything spotlessly, new o-rings with a tiny dab of silicone grease. The worst leak has stayed with the hose, so I'm suspecting the hose\banjo. Nothing obviously scored or marked.

<span style="font-size: 0.8rem;">I'm reluctant to replace the hoses with the same as they've always done it, just taken me ages to track down the source of the squealy brakes.</span>

WWSTWD?

No bleeding, but we do have reigning.

I've had this happen to Magura hoses. They were leaking where the hose enters the banjo and I couldn't see any way of tightening that side of the fitting on mine so I sacked off the shigura idea and sold the Magura calipers and fitted shimano throughout.  18 months and around 1500 harsh miles later still no issues.

Fwiw I use cheapo M4100 levers to avoid the wandering bite point issues associated with servo wave levers, which was the reason I tried maguras in the first place, and then the levers leaked so I went to M4100, then the hoses leaked so that was the end of my Magura love affair! Those M4100 levers have about 2000 miles on them now, pretty good for a £14 lever!

Has anyone replaced just the Banjo's? Don't really want to spend £30 an end on new hoses if I can help it.

Or the even cheaper eBay version? Ideally I'd use the hope style with a copper washer each side, anyone know of a source?

You can't just replace the Banjo fitting as it's crimped on by a specialist machine that you/I don't have access to and can't replicate at home. You will need the entire hose.

I've never used anything other than Magura stuff - I can't help with the parts you've linked.

FWIW I've got two pairs of Magura MT5 and never had a leak or any other issue - so stick with them. They're good brakes but you've clearly got a problem.

I used to make hydraulic and high pressure air hoses offshore, and used a mixture of swaged (as you say the original Magura banjo is swaged) and compression fittings.

The lever end is compression (and using a mix of magura and Shimano) so I don't see why a compression banjo fitting wouldn't work? All the aftermarket kits come with compression fittings at the caliper end.

I agree - it could/should work. I have used compression fit Banjo fittings on cars as well. So it may work but I've never done it with a bike brake :o)

So the eBay special banjos appear to have worked and barring a borderline too short front hose were pretty easy to use.

And for anyone else doing a Shigura set-up I've just replaced the too short hose with a Shimano XTR one with a banjo that also appears to be fine with magura caliper and bolt.
