Brake Booster vacuum hose and Weber carb

[JohnboyLandy]

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.

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
