The 2009 edition will have 'V' brakes, although they may be called 'cantilevers' or something else that describes roughly the same thing. This is base specification for an MTB, to be assumed unless stated otherwise.

Disk brakes are better in the wet because the braking surface stays nice and dry, however, you can still stop in the wet with V brakes. We have already had this question:

Why are disc brakes rare on road bikes?
