Ok, I’m gonna ask… The post referred to it as the emergency brake and you seem to be doing the same…
Is this something I don’t know about? That what we UKians call the ‘handbrake’ (or, more recently, ‘parking brake’ as since they became electronic and no longer use a hand-operated lever, all the vehicle manufacturers use a red P on the button, and on the dashboard to tell you when it is on) you USians call the ‘emergency brake’?
You only use it in case of emergency?
