Narrative:

Taxiing into ZZZ. Captain had completed turn. Taxiing straight ahead he stated he had no brakes. I did not perceive his taxi speed as excessive for the conditions. Apparently the ramp had a thin layer of fresh snow on top of ice. I queried if I should set the parking brake. He agreed and shortly afterwards the airplane came to a stop. There was no damage to equipment or personnel. A ramp employee stated he threw a chock under a wheel because it appeared we were sliding.
