Cargo rail breaks

[Mittens]

Anybody else having an issue with the breaks on cargo rails not working?
Im considering putting up a bug report but I wanted to check an make sure im not missing something.

I have both the button and the Sliding connector gripper powered, the button is toggle and connected to the breaks on the connector gripper (all of this is in advanced mode btw) there is power being provided but the connector gripper simply doesn't stay put, its as if the button isnt even doing anything.

Am I missing something here?

Have the same "issue" but in my case I assumed it's because I have to much weight on them which the brake simply can not handle. But actually I do not know if there is any weight limit to the brakes.
