So the seat can come forward under braking? If so then I think this is a failure, even if it isn't its dangerous anyway.

If it isn’t 'secure' it's a fail. Mine is secure unless you move it, then it can only be secure in one place because it can't move the holder so slides all over. So I held it in place with a screw, so you can't move it and then chuckle at a 6'5 man of fat squeeze in.
It is secure, it just wont operate and tilt the seat forward.
