I have a '97 Outback. It's been really cold here, and I've noticed when I
first hit the brakes, like when backing out of the driveway, the pedal is
very hard and nothing happens. If I keep pushing it eventually gives and I
have brakes again. Either that or let the car warm up quite a bit. Pedal
is a bit mushy otherwise, but that seems to be pretty normal in this group
from what I've read so far.
Anybody know what's causing this?
Thanks.
Sheldon

A previous poster had a similar problem. Probably the check valve in
the vacuum line was the diagnosis. Here's the original thread:

I've been out in 0F/-18C and had to warm up the car for at least a
minute before the brakes are normal.

(Very bad form to crash the car on the way to a call, too.)

Hi,
How old is the brake fluid? More likely it is contaminated with
moisture. Flush and refill. Brake fluid doesn't last forever.
