I have a mountain bike with 26" wheels and I wish to change them to 27" road bike wheels. If I get the correct gear set on the rear will my braking system grip a thinner rim and will the axel be the same width?

The hub axle will be the same width. The brakes, however, will not work. I've seen this transformation done, but only by building a 27" (700c) rim onto a disc brake mountain bike hub and they ran disc brakes. Your best bet is just to get the thinnest, slick 26" tires you can find, and put them on your existing wheels. The rims are actually quite close to the same diameter, so you wouldn't gain much by going bigger.

You can't do it for a number of reasons:
1- The brakes will not line up, and most road wheels are 700c, not 27" (yes, there is a difference).
2- The axle spacing on a mountain bike is 135mm, but road wheels are 130mm. Your frame will not take the stress on the dropouts.
3- Even if you have disc brakes, you would need to have mountain disc hubs built up with road rims and would most likely have eternal shifting problems.
If you want a burly road bike, get a cyclocross bike. If you want a mountain bike that's faster on the street, put 26 x 1.0 tires on your existing rims. If you want pure speed, get a real road bike. Save the Mickey Mouse jobs for emergency trailside repair.

brakes will be your biggest problem,i doubt that they would be efficient as the blocks would have to be let out to maximum to reach anywhere near the rim,i would also doubt they would adjust high enough to allow for the 1 inch difference in rim size.
