If the brake pedal feels hard the first time it is pressed in the morning, it could be due to a problem with the vacuum supply hose for the brake booster. A revised brake booster hose is available to address this concern.Google+

Brakes get hard and don't stop the car. Replaced master cylinder and brake booster. Suspect issue in check valve.
Only an issue when outdoor temps are below 30 , first time I push brake to put car in reverse its ok then brake pedal reak hard and brakes barely work, almost caused accident. If you let it run for a minute or two you can hear a very quiet "click" then brakes work fine. One time at -3 degrees the brakes did this while driving, very dangerous
