    I'd have the brake fluid flushed to make sure there isn't any water/moisture in the brake fluid that may be icing up in the cold.

    Tell the mechanic what it's doing...don't just ask for a brake fluid flush with out letting them know about the problem.

    Master cylinder suspect. Swap it for a new one. You can buy refurb kits but a swap is quicker and easier.

    Check for frozen parking break cable.

    Flush and bleed the brake fluid.
