Q&A

First: The car has been off for several hours. Next: Get in and start the car. Put in gear and start on your way. Problem is noticed when you need to stop. The force required to get the brakes to function is equivalent to having no power assist at all. Pumping the brakes several times will bring the pedal force back up to normal if it's not too cold outside. If it is cold the power assist doesn't work for up to 45 seconds when outside temp is below 32 degress F. This started happening this winter so I thought that there must be moisture freezing somewhere in the brake system. But it's been doing it briefly when the outside air temp is as warm as 60 degrees F. Any ideas? Thanks! Neil
