bigger brakes dont improve stopping? so a larger surface,bigger pads and more pistons dont matter?
i went from stock gen 1 brakes to an upgrade kit i put together which includes 1995+ pads,rotors,calipers and also ss lines..i also changed over to dot 4(which only has a higher boiling point). im here to tell u my car not only stops faster but more consistantly and my brakes dissipate heat much better.

By the way for the bigger brakes to stop better with stickier tires the grip has to be so large that the smaller brakes cannot lock the brakes up (actually enough pressure that you are almost locking the brakes since that will give you the least distance)
Another myth is that wider tires make you brake in a shorter distance, also not true. The only reason wider tires do make you stop shorter is because they have a softer compound that gives more grip, they can use softer compound because the wider tire puts less pressure per square inch of contact area therefore not wearing as quick, but if the wider tire is compared with a narrower tire of identical compound and tread design the stopping distance would be near the same I should add same aspect ration on both tires

No sir, big brakes only help you stop faster if you have stickier tires, that is the first time, what big brakes do is, stop with less brake pressure, reduce brake fade if you are continuously using your brakes hard (like on a race track). But if you have two cars with the same design and the same tires your stopping distance (assuming its not heated by repeated previous braking) will not change. Because you can lock, or activate your abs with both brake systems. you will need less pressure on the brake pedal with the bigger brakes

A point to note REF tyre width, having a wider tyre does not = a larger contact patch.
Think of it this way. You have 30psi in your tyre and 30lbs acting downwards, this means your contact patch is one square inch regardless of tyre size and width. What changes with a wider tyre is the shape of the contact patch, which becomes wider and shorter and has its own benefits.
This leads to sidewall height, wider tyres often have a lower sidewall height. This decreases the tyre deformation as it rolls both in a straight line and cornering, reducing buildup of heat and therefore allowing a softer compound to be utilised.

you are 100% correct on every point you made.
Also surface area has absolutely nothing to do with friction.
The force of friction that your tires can apply without locking your brakes equals the force applied (weight on the wheel) times the coefficient of static friction.

And six ways I will agree. 
I will also add a seventh...aftermarket engine computer-chips. They may increase power, but can also cause problems with emissions, engine-drivability, engine-life, operating temperature, and a number of other factors, not to mention possibly voiding the engine-warranty. Engineers design cars at the factory and put the specific parts on that they do for a reason (assuming no interference from company-management)....and they study long and hard to get those engineering-degrees.
Of course, that doesn't mean that I always totally agree with the way cars are designed. A number of vehicles today, for example, IMO, have stiffer suspensions and lower-profile tires than are ideal for typical everyday driving, especially on rougher roads. The result, of course, is lower ride-comfort.

What they do, at the most basic level, is dissipate heat better.

This is very true.
A point to note REF tyre width, having a wider tyre does not = a larger contact patch.

This leads to sidewall height, wider tyres often have a lower sidewall height. This decreases the tyre deformation as it rolls both in a straight line and cornering, reducing buildup of heat and therefore allowing a softer compound to be utilised.
