Brake problem - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Sometimes when it gets very cold, the brakes act as if the power brake assist (on a 72) is not working. Sorta like trying to use the brakes with the key off. You have to push real hard.
Planning on getting all the old fluid out of there and replacing it with new.
But, is there a possibility that moisture has gotten into the power assist and is freezing up? If so, how do I fix it? Replacement?
Again, if so, does the master cylinder have to be replaced also?
Thanks
