ok i have a 05 MR befor this i had 3 03 gsr's. i never seen the booster line spliced befor and in the short peace of ine there is a one way valve. i was just wondering if they all have this one way valve. if you could check you car that would be very help full to me. all you have to do is squeez the vaccume line and see if you can feel something in the line.
thanks for your help guys

 

Anyone

 

All vacuum brake boosters have a one way valve. its to keep from crap from the intake getting into your booster, and to keep the vacuum in the booster. hth

 

Thank you, I just couldn't remember....
