I bought a second hand set of Hope M4's recently and which have come with a set of goodrich hoses on them. When fitting them to the bike, I undid the front banjo to adjust the line of the front hose. Unfortunately, i've split the rubber o-ring seal, and now the seal is gone totally.
Its got me wondering though. Should it really only have an o-ring seal? With the current setup, I have:
Caliper : Banjo : Rubber O-ring : Bolt
Should it not have a copper washer seal on each side of the banjo?
Caliper : Copper Washer : Banjo : Copper Washer: Bolt
A browse on the web seems to show a couple of different setups .
This has 2 washers:

What do you lot have?
All mine have a copper washer each side of the banjo
Thanks TJ. Confirms what I thought should have been the case. I'll get some washers asap.
contact hope bet they post them out FOC
Hope fittings have copper washers, Goodridge have O-rings, and are recessed to take them, if I remember correctly.Probably not a good idea to fit copper washers to fittings designed to take O-rings.
Well waddaya know? I went to have a closer look at mine as I have one Goodrich hose amongst 8 hope brakes - and on the Goodrich there is no sign of a copper washer 😳 At the banjo - its the only fitting I have not had apart IIRC
As above. Both work but only when matched to the correct fitting. If you split an oring, replace it with an oring.
