that's sweet, i appreciate all the feedback i'm receiving. i called marlin, allpro, trailgear, sky and every auto parts place under the sun and nobody could give me an answer. they all acted stumped like it was the first time anyone had ask this question. i ordered a new booster but just got a new one for my truck, 85 4runner sr5 4cyl. should i cancel this order and get the v6? i'm not sure which model truck to use, any ideas?

 

not a stock booster ..

I have one comming from a T100 duel diaphram .. apparrently the 2000+ 4runners use the same booster .

 

fixed the problem. used a 94 4runner booster, dual diaphram and my brakes work nice. they are better than my jk with 4 wheel discs. when you upgrade the master cylinder you have to do the booster also. some have gotten away without but the difference i noticed when i swapped mine is incredibly different.
