65 gmc brake problems - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Am new here, so here goes. I have a '65 gmc half ton 2wd pickup. I've never
had good solid brakes, but have just driven around the problem. I finally got
fed up and decided to fix them. I have good pedal on the first couple of applications, but after about a block or so, solid pedal, but the brakes just
won't stop the truck very well. I have checked all the wheel cylinders, adjusted the brakes, new master cylinder (bench bled). I found one front
wheel cylinder that seems to be leaking, and will replace today. Could the leaking wheel cylinder cause air to get into the system?
