    Brake Booster vacuum hose and Weber carb

    Hi All,

    Just looking at my brakes and how to make them as best they can be, so I have a question about the brake booster hose and the weber card I have.

    I noticed that the booster hose is connected to the carb with a junction shared with the crank case emission valve, so I'm concerned that I'm not getting full vacuum for the booster with this shared arrangement.

    pics :

    I've tried to highlight the junction in the pics with a red circle.

    Any thoughts on this arrangement ?

    Thanks
    John

    Thanks for posting the pics and the info. That all tells me I should have a dedicated port on the carbie for the booster vacuum hose. I'll see what I can do.

    Cheers,
    John
