C10 Brake Booster

[Mike-P]

Hey guys,

I installed a brake booster on my truck earlier today. I was told it worked by the person I got it from who repainted it and gave it to me when they sold the truck. I attached the vacuum line on the front of the manifold. Put everything on and the braking doesn't seem to be much easier than when I just had the master.

Do you think that this could be a faulty booster or perhaps the brake needs to be adjusted? I almost have it fully extended with leaving about 6-7 threads on the adapter.

A bit stumped here. (Did the typical youtube tests and it doesn't seem to be getting any stiffer when stepping on the pedal after vehicle operation).

Any help would be much appreciated.

Thanks,

Mike
