Default squeezing the best out of factory brakes

As of now i have all rebuilt callpiers whith oe spec pads and for fluid im running ate race blue,the brake lines are still good, and factory brake booster.

i know to get the best out of the brakes i should get better pads and ss brake lines but does any one know how to get a little better performance from the factory breaks? at auto x i have to hit the breaks like im tryen to break the peddal, while my buddys lexus is350f a small tap and you get full pressure( i know the teck and desighn are decades better) any little tips to optimize factory brakes

maby a new booster from one of the toyota pick ups might help?

share the little tips you have learned over the years

You've answered the question yourself already. Pads and new lines (the lines don't have to be stainless braided, just new OEM should provide some improvement). A different master brake cylinder isn't going to do much if your lines, calipers and pads aren't up to delivering the friction needed. If you don't want to fork out the dough for Porterfield pads look at EBC's offerings.... even the red stuff pads offer a significant boost in performance over what you'll otherwise get at the local parts store.

As for the brake booster, I don't recall anyone ever trying to swap in the whole assembly, just different master cylinders. The 4Runner's master cylinder bolts right on and came in a couple different bore sizes. Hit a salvage yard, grab a couple from a couple different years and try them out. I think there were 5/8", 3/4" and 1" bores depending on year and model.

yah i imagines this would be the next step, i know the factory brakes will never be as good as my friends 09 is350f but i dident know if there was something i had missed on getting better brakeing( besides stepping up to a full big brake kit which i bet will match lexus or even far surpass it)

Well, there's the dual pot front caliper swap from the Toyota Previa minivan.... but there was never any solid info showing that they worked any better. The contact area really any different as the two pistons were each much smaller than the Supra's one. It is a straight bolt on affair though from what I recall. I'll bet you there's a reason you probably haven't heard much (if anything) about it.
