    Hi, first of all, I love this forum! Alota good info!
    Second, my 79 blazer's brakes seem to need pumping up in the morning: when I first start driving, the pedal will go to the floor the first few minutes of driving, SOMETIMES. I pump it once or twice to bring the pedal up. After that, they're fine for the rest of the day. The fluid level is good,
    so what the hell?! Master Cylinder jacked up? I heard the rear drums can also cause somethin' like that, but THAT dont sound right. /forums/images/icons/confused.gif
    thanks,
    james

    That sounds like a bad master to me. They can leak internally and the fluid level will stay full...but it can still be leaking.
