i need to roll start my rx7 and i was wondering if the brakes still work with the engine off? and how effective is the handbrake.. i need to roll it down a hill..

thanks

 

Yes, brakes will work and so will your e-brakes just as effective as the car on.

 

yes

 

thanks for that! its just that i used to have a subaru and with the engine off the brakes didnt work.. at all!

 

The brakes should work in any car. It will probably take a lot of force for any effect through the pedal once the vacuum boost has been lost (sat or used already) - the parking break should be good, but it'll also take some muscle to get all the way so that they actually stopping you.

 

As sar mentioned, the brake vacuum booster is not working with the engine off, so using the brake pedal requires a lot more effort.
