My wife's 2001 Lesabre has no brakes when she first starts it in the morning. What should I check first. I know it probably has something to do with the pressure building up in the brake booster, but what is the remedy?
 
Bad brakes booster, it may have just came loose or disconnected or it could have broke so take it to your local mechanic and have them look at it. Also tell them to look at the brake proportioning valve.
 
its a vaccum leak somewhere.. or you need a new pcv valve... look here... mostly what it is...

see the long hose coming from the right ... going into the huge black circular container... yours has this somewhere...
well that hose has a pc valve connected to it at the end where it connects to the black thing... usually they get old and stick... you can try cleaning it or buy a new one. You should be able to blow only one way on it...
