If the brakes are new, chances are they just need breaking in. Find a section of trail that has a smooth long downhill section. Ride down get some speed and then halfway apply (drag) the rear brake to try to break in the pads.
Or, someone touched the rotors or the pads with oily fingers and contaminated the system. I would take some denatured alcohol and wipe the rotor clean.
If that doesn't solve the problem, you may have to cook your pads. You can bake them at about 250 degrees for 15 mins. Just make sure put some aluminum foil below to catch any dripping from contaminates.
