After reading through this post to catch up on whats going on, I have to the conclusion that half the posts made here are bullshit, people are just talking out of there asses, not one logical explanation was made.

It seems that no one thought of the most logical explanation which was air in the brake lines.

I know ha, how annoying can it get when your trying to explain things to some ppl who probably have never even changed pads on their cars before.

No insult intended, I'm open minded.

Hahah... it's kinda funny but when they're not open to suggestions/input it just becomes sad....

If you think about it, the brake master cylinder is a tube with your "pedal" pushing the fluid through. The thinner the tube, the less feel you get through the pedal because you have to depress it further in order to get more fluid through to the calipers. The thicker the tube, the more sensitive the brake master becomes when you press the pedal as your pushing a greater "initial" volume through (I don't know how to explain it any better). For example I believe the sizes are the piston/tube diameter of the brake master? Ie. 14/16", 15/16", 1", 1 1/16" etc (Atleast for Nissans

)... but I'm not sure on that diameter thing, could be something else like radius *shrug*?

When you install larger calipers, namely 4 pots etc over stock say.... 2 pots. Because of the extra pistons, more brake fluid is needed... thus more volume thus you need to increase the size of the brake master in order to retain the stock pedal feel... I hope that explanation makes sense.

The Cusco BMC stopper does nothing to aid this, it's purpose is to reduce firewall flex... which is where your brake master cylinder/booster is mounted. As with some cars, the firewall bends when you press on the pedal because of the force put onto it. The BMC stopper simply holds against the pedal force so the feel is more direct to the brake master under firewall flex...

You can buy all the add on crap you want, but in the end, it's not going to fix the issue if you don't know what's going on in the first place...
Back on topic, if you still feel the brake pedal feel isn't to your liking, ie. too soft after PROPER brake bleeding and checks to see there are no leaks or your current brake master doesn't need a rebuild... then you need a larger brake master and vice versa. Good luck
