Handbrake - e brake. A little help,chaps

[Paul Y]

Evening,

I think I am being stupid but not too proud to ask for a little help.

When I pull the handbrake (e-brake) the outer cable that runs through the firewall moves with the handle meaning that the pulling movement does not translate into moving the cable that mounts to the rear brakes.

Should the outer sleeve be held somewhere so it doesn’t move or am I being stupidly and the inner cable is seized within the outer as it goes up through the firewall?

Not sure that makes sense but hopefully one of you clever souls will understand how it works and chime in.

Thanks.

P.
