Brake Issues after 2.0 swap

Hey guys, i just did a motor swap and installed a weber/pacesetter and after getting everything installed i went to bleed my brakes...

When the truck is running and i hit the brakes it raises the idle quite a bit... And the more i pump the brakes the faster the idle gets..

Im pretty sure it has to do with the brake booster or vaccum line, Have any of you guys had this issue? what might some solutions be?

Need to figure this out soon because i cant drive it with the brakes with it acting up like this

Thanks guys

No ideas anybody?

mine did this when it was low on fluid

Thanks for the help... this might be my issue... my master cylinder is full but all of the brakelines in the truck are Brand New.. so maybe i just have to continue to bleed them better??

I was thinking more along the lines of a vaccum issue but ill try and bleed out all the lines better.

Thanks again

I had to bleed my brakes much more than I thought I did. Make sure the resevoir is at least 3/4 full.
