Tried rolling my car back a little into the shade without turning it on and had to press extra hard on the brakes for it stop.

I’m just a mechanic idiot, but I was under the impression that brakes and many times steering is power or power assist.

Back when I was a kid we called them power brakes or hydraulic brakes.

Anyway with no engine on, there is no power boost to the brakes. Worth engine on, you get the power boost.
