braking issue

[camaro427-69]

thanks for your opinion tobin. i´m getting around 12" on engine and 18" on pump. but i don´t know if my gauge is that good but it´s a different number. the only difference i can tell is that without pump just with vacuum can i can barely brake. also like you said i´m feeling that when i brake first time i have way more assistance than after couple times in a row. is it a good idea to hook a vacuum can on if using a pump? probably i should hook the pump testdriving it.
hmmmmmmmm so did i swap something bigger stock to smaller aftermarket . so where´s the improvement on that? looks like i did some "looks shiny i need it" buying.........
