running a smaller booster.

Hey guys, I have a 94 s-10, and i am currently in the process of swapping the power brake booster. I bought the 7" booster and master cylinder setup from waylayed inc. And ever since i swapped the booster/master i have had no brake assist whats so ever. Any one with this booster or switching to a similar booster run into this issue? I go to hit the brakes and the pedal moves about an inch to 2 inches. The truck does not stop it just slows down until it finally stops.... any ideas or anything? we replaced the booster 2 times and the master 3 times.

did u bench bleed the master, then re bleed the truck?

yea. did that each time we switched the master around.

that master sucks use your stock one it bolts right up. did you get the single or dual diaphram?

the bore size on the original is different for that booster. can i sill use it? and it was the single diaphram.

single diaphram pretty much sucks I have the dual and my stock master bolted right up to my 2002.

well the 98+s10 master fits this booster but my stock 94 didnt fit. so i should go to a dual diaphram.
