Ok, so this is to help oem bike manufacturers by not having to bleed the brakes after fitment.
My question is how?
It's not like it's a sort of one way valve or something, so how does this unassuming little device work?
Isn't it just SRAM's version of the compression fitting? Hope use a very similar one, just a push fit rather than screw fit.
You might be lucky and not have to bleed the rer brake, I didn't on my Hope V4's even with shortening the hose by about 4".
Hiya, not asking due to having issues with the brakes or anything btw.Very happy with them ! lol
No, just genuinely curious because as you say, the setup up looks very similar to normal sram /shim. Other than the olive is threaded.
There must be an advantage to the oem market but I wonder what it is?
It's a sealed end to the hose with the lever separate. You feed the hose though the frame then connect to the lever at the end. Because the hose and caliper are filled with oil, as is the lever, and in theory you don't lose oil when you connect then you don't need a bleed. Unlike connectamajig it's a one hit wonder. Once assembled it's just a regular brake.
Haha, no don't worry I didn't think that!
Not why it's threaded, I think it's just SRAM's way of doing it. It's actually a bit more complex than the usual push fit barb and olive slives on.
I'm still in the dark to how it works though.lol
Is the olive sealed in some way until fitting to the lever?
No the olive is just an olive. I guess they throught it screwing on was useful in some way I can't really decide.
Stealthamajig is an OE thing for sending you brakes in 2 pieces so you can route them through a frame. Shimano have the same its called a J Kit. 2020 aftermarket brakes are shipping like this I believe.
The Stealthamajig olive is really from a user perspective just an olive that screws onto the barb. Otherwise its no different to the old OE screw barb and loose olive system. Whether the olive _needs_ to screw on in order to break a seal in the lever for first assembly or similar I do not know. I suspect its to maintain correct alignment inside the lever.
Did I imagine it, or wasnt there a version with two pistons, so you screwed the ends together so one pushed on the other meaning you could disconnect the lever from the caliper without any risk of fluid loss?
There was something similar for 'breakaway' tandems?
They do a connectamajig coupler, I understood it was designed for OEM assembly, to prevent the need for a bleed and reduce inconsistent bleeds on OEM bikes.
The stealthmajig threaded olive ensures the olive/hose end is located correctly, with a loose olive the brake hose must be held in place as the nut is tightened.
Im not sure if they do that now. Its just a plug on the end of the hose. The threaded barb is preinstalled has a threaded plug on the end to stop the oil leaking out, so maybe thats why they now use threaded olives, just to reuse that.
