Brake booster ... does anybody knows iff a bad brake booster will make my rx8 turn off ???

 

Brake Master Cylinder? And no, I don't see how if the check valve is working correctly.

 

Yea because it has a whistle noise wen go in reb so i was thinking it might be that and it turns off

 

Go in reb?

 

Reverse and i tried bay unplugged and don't day anymore but won't stop wen push the brakes

 

clamp the line and see if the symptoms persist. a ripped diaphragm in the booster will cause a major vacuum leak in the intake and could cause a stalling condition. you won't have any brake assist, but sounds like you don't anyways.

and try to use an english converter or something, it's difficult to decipher all of this.
