Could someone explain to me what a muzzle brake's function is?For example a Mosseberg 500®/590® Special Purpose shotgun's muzzle brake?
Muzzle brake?

A muzzle brake's function is to reduce recoil and help to control muzzle rise during firing.

a muzzle brake works by redirecting a portion of the high pressure gas stream that without a brake pushes the firearm back into your shoulder in a manner much like a rocket.
In my opinion shotguns don't have a high enough muzzle exit pressure (yes I just made up that term) for a brake to be very effective

Muzzle brakes reduce the rearward thrust of the rifle or shotgun under recoil, by redirecting the gas discharge to the sides and rear so as to push the gun back in a forward direction. This differs from a compensator, which redirects the gases upward to reduce muzzle flip, i.e., the upward rise/torque of the gun under recoil. Compensators are mostly for handguns, muzzle brakes for long guns.

At this point in the conversation, I would like to jump in and thank you for using the correct spelling of "brake". That is probably my biggest pet peeve. As a matter of fact, thanks to everyone in this whole thread who, up to this point, have used the correct word.
Carry On.
Carry On.

So I was looking at competition pistols and saw that some have something that looks similiar to a muzzle brake, is this a muzzle brake?

hmmm.... good question... there seems to be interchangeability with 'muzzle brake', 'porting', and 'compensator' within the industry...
From Remington's website referring to the VTR:
Personally I wouldn't say that the VTR has a muzzle brake, I would lean more towards compensator...
This article from Wikipedia has lots of examples and explains them fairly well...

That gun in the picture seems to have elements of both. It has porting at the muzzle - in fact all the way down the barrel - which would be a compensator, but also side ports characteristic of a muzzle brake.

You and me both brother. I've been accused of being a grammar NAZI more than once for pointing this out.

I have a Mossberg 500 12 ga 20" barrel that I had ported to reduce recoil and barrel rise. The porting did not reduce the recoil as far as I can "Feel" but it did reduce barrel rise.
[note - misspellings of "brake" vs. "break" are from the website, as are the missing possessive apostrophe in "shotguns", random capitalization and using "insure" instead of "ensure"]
I found one online, but something has me puzzled about it. The instructions say "When mounting the Muzzle Break to your Shotgun. you must insure that the front of the Muzzle break does not stick past the end of your shotguns barrel".
I don't understand that - it sounds like it defeats the purpose of having it if it's fitted all the way down the barrel.

This one? Gimmick, pure and simple. Just for looks.

The ports in the breacher attachment allow you to put the muzzle directly against the item you want to blow into the next universe. The ports allow the gas to escape around the sides. If you were to try this without a breacher, you could possibly blow the gun up.The alternative is to simply hold the muzzle a couple inches away from the target, but being able to place the gun directly on it is much more certain. You are also likely to miss due to the recoil, which is nearly uncontrollable with a pistol gripped SG. The toothed end of the attachment allows the user to bear down on it without it moving, even during firing.
The Mossberg posted above is the style used by entry teams for breaching doors. That is about the only you will see a pistol gripped shotgun in use by a professional. The PG allows it to be small enough that it can be carried in addition to their "real" weapons. In this application, they aim with the muzzle, not the sights.
Will you ever need to breach a door? Not Likely. But the breachers do look cool.

'Cause it's locked and you don't have the key?

That's good stuff, KarlIt's a door breaching device designed to provide the proper spacing for blowing out a deadbolt lock or hinges. These are very commonly used in Iraq to make entry through a locked door. Also sends shards of wood and metal into any bad guys that might be in close proximity on the other side.

Muzzle brakes are also useful in helping the shooter to go deaf. Not a common goal but the results would speak for themselves if anyone could still hear them. OK, OK...propellant gasses usually amount to a significant percentage of the mass expelled when a gun is fired. If they all go forward they will contribute to recoil. Porting allows them to leave in a different direction (out the sides, up and back, etc.) From the projectiles, thus decreasing actual recoil. Most designs take things a step further and use the gasses as thrust rockets to drive the gun/muzzle in a new direction. This is based on the velocity and mass, not the pressure, of the gasses.
Flash hiders serve the dual purpose of making the muzzle harder to clean and scaring politicians.
Breaching fixtures (al la that mossberg picture) are probably the most useful of the lot. OK, I'm somewhat kidding, but muzzle brakes are either optional or a sign of a too-hot cartridge for the gun, flash hiders really don't do much at all unless you are in a night firefight, but the breaching fixture can keep the barrel from popping if the gun fires while the muzzle is in contact with any hard object, and keeping the barrel intact is a good thing.
