Pontiac: Bonneville brake problem

Anyone know what to direct my mechanic to?

When it is extremely cold ( 15o F or below). my brake pedal becomes quite
stiff. When I pull out of my garage in the morning, it is usually fine (
warmer!). I park at work and at the end of the day, I have my little brake
problem. I start the the car, warm it up, put my foot on the brake ( the
pedal works normally), put the car in reverse, let up on the brake pedal
slightly, beginmoving backwards, push the brake pedal, and...the brake pedal
does not go down. If I shove hard, I can slow and stop, but there sure can
be a scary moment. After the car warms more, the pedal works normally.

I always remember this the first time cold weather hits us, and I have the
experience. Once I have it, I change my driving behavior. By keeping my
foot on the brake pedal while the car is initially warming up and in park, I
can cause the brake pedal to function normally. It doesn't move( but I am
sitting still!). Once I feel the brake pedal sink to the floor, I have
normal brake function and I am good to go.

Only happens when cold or high wind chill...I forget about the problem when
it warms up! However, it is time to rememdy the problem.

Bonneville is a '94 with 136,000 miles on it. Car will get passed to
college age son in a year...needs to be safe!!! ( College age son now
drives a '91 Astro with 360,000 miles on it...surely my Bonneville has lots
of life left!

Is there a "Click and Clack" out there with an answer?

Takes FBR advice and have your brake fluid replaced and complete hydraulic
system inspected as soon as possible!
