Will the brakes function with engine off?

[jing]

you may find this a stupid query but will really appreciate your technical input.
will the car brake system engage even if the car's running downhill with engine off?
thanks!

[ssaloon]

it will work but not to it's full extent since your brakes are power assisted. since the engine is off, you will be relying on sub 100% brakes. you'll notice this when you pump the brake pedal while the engine is off, it because very hard and spongy.

Assuming that the brakes are power-assisted, no. Or at the very least, it will be very difficult to operate them. The engine has to be running in order to supply the electricity necessary to operate them.

wat electricity? u have electric brakes? if ur talking bout brakes in your car, it will still work wit the engine off, but it will be hard to push the pedal.

[boybi]

brakes are vacuum assisted. if the engine is not running, there will be no vacuum supply, hence, very very hard to engage the brakes.

tama sila.. its true

[OTEP]

The system has enough vacuum for about one or two more uses even when the engine is off. After that, the brakes are still there but without assist so you have to exert all the pressure.

The parking brakes are cable operated and work the same whether the engine is running or not.

yes. basta inapakan mo at walang topak like 'no brake fluid' or idiotic things like that.

[the_wildthing]

e-brakes will work.
