My off the peg bike arrived with a Connectamajig fitted to the the end of the rear brake hose, joining to the caliper. Strangely not fitted to the stealth Reverb.
I cant find any info from SRAM on it being used in this way. Obviously it allows me to reroute the hose, but I'm not convinced it's designed to be used in line with a brake.
Has anyone tried this or had any issues. The Connectamajig is in a slightly vulnerable position. Also, I wonder if it could heat up along with the caliper and jam. I did notice some strange behaviour yesterday (which I attributed generally to SRAM brakes at first).
I'm tempted to remove it and fit it to the Reverb instead.
Its a stealthamajig and yes its meant to be there. The reason you've never heard of it is because its found on OE brakes only.
I assume reverbs operate at a lot less pressure than brakes, and would therefore question whether it is man enough for the job?
Yeah, it's the pressure and reliability issues that concerned me.
Googling "stealthamajig" doesnt return much info...
Commencal have just emailed me to say it is an option for brake or seatpost on most bikes (but the Meta v4's frame design doesnt allow it to be used on that bike)
Formula offer a similar quick disconnect for their brakes.. I imagine you won't die 🙂
quick disconnect on brakes? What can possibly go wrong? 😆
Yeah, I'm sort of with andyl here, why complicate?
Now had confirmation from Fishers for anyone interested.
The brake version has different seals to the Reverb one, so not interchangeable both ways, but designed to be fitted to a brake

You get them on rim brakes, don't you?
Quick connect's common enough on race motorbikes (where it suits the events). Can't really see the point, on pushirons, though. Removing/refitting isn't exactly commonplace.

are we talking cable or hydraulic?
If the former you mean just the tension release so you can get the wheel out? Seen plenty of people not engage this right or forget to and set of and wonder why they have no brakes.
I use push fittings a lot for pneumatic and hydraulic/resin applications where I need quick release and generally I prefer them to compression fittings but I just wonder if on a bike the fittings will be very small and thus not quite as reliable as they should be and also subject to getting knocked/damaged. Not seen what these things look like though.
I was thinking they might be different to the reverb one as the reverb uses mineral oil but sram brakes use dot 4 don't they so might need a different seal or they are different to prevent them being mixed up and causing contamination or someone trying to use a reverb lever for brakes or vice versa (brake lever might blow the seals in the reverb).
They're pretty robust and hardly quick release. The purpose is to allow manufacturers to route your internal hoses through the frame without having to refill the brakes afterwards, not for onwards disconnection/reconnection.

They're popular on bikes with S&S couplers. Can't remember who makes them, might have been Goodrich or hope?
They work by simply terminating the hose with a piston at each end, attach the two ends together than the pistons push on each other and Roberts your mothers brother.
Surely this is the same principle as the hydraulic hose connectors used on, for example, an excavator which will swap between a bucket and a breaker with many, many, many times the force of a bicycle brake going through it? I see no reason why a scaled down version wouldn't work.
