My car's power brakes don't work that way, if I touch the pedal I can hear the "hiss" sound and the vacuum will be depleted within seconds.

I just learned how to control the car without power brakes and ABS, it's not that hard.

Could be you have a problem with your system, maybe a leak or cracked hose? I've never heard a hissing noise from any power brake system.

I dunno, it doesn't hiss when the brake isn't being pressed and doesn't use any vacuum that way. When the engine is on the brakes work just fine, pedal feel is pretty light.

It's not so much of a hiss as it is like the sound of a person breathing through a straw.

Sounds like something's wrong with the brake booster or the hose to it

Get that fixed and you should get at least a couple of pumps of the brakes with the motor off

I used to use one long, light braking action when I was driving the Black Widow, and very rarely did I run out of brakes. Once or twice I had to key it back on, but not once did it cause any kind of emergency stop.

You can also use the e-brake for assist if you have a handle, not a pedal.
