Whoa Nellie! Brake pedal to floor! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just had a weird problem. My truck has been apart for a few months, only going around the block on occasion.

I started her up just a moment ago, let it sit for about 1 minute & went down the driveway. The pedal just kept sinking. Very soft.

It acted almost like I had air in the lines. I was driving around town w/ a nice hard pedal in November.

I didnt' see any obvious leaks. The only weird thing was the front chamber of the Master Cylinder was full to the top & the read chamber was just over 1/2 full. Stock 1970 drum/drum.

What do you think is going on? Leaky cylinder letting air in? Bad MC?
