Re: below freezing, braking problems.
Remove the wheels, open all four bleed screws, remove the brake fluid cap and fill up as required. Close each corner as clean fluid starts coming out. On modern 4-channel ABS cars there's really no order to bleed the brakes in, since they're all independent after the ABS pump. Just get a helper into the car and give each corner a few strokes to make sure no air snuck in.
ATE Super Blue makes it really easy to tell when you've fully flushed the system because as the name implies, the fluid is blue. When you see the colour change, all done.
Given that it improves as the car warms up, I'm wondering if maybe there's a moisture issue in the brake booster or the vacuum line from the manifold. Is it the pedal firmness that changes or the "grabiness" of the brake pads?
