I've bled the brakes several times on my '49 Chevy 1/2-ton, but they still seem soft. If I pump the pedal twice, it goes down about 1-inch farther on the first push than the second push. Is this normal, or is there air hiding in my system? Any advice for getting the same push every time? The master cylinder and brake lines are all new, and the wheel cylinders have been re-built. No leaks detected. Thanks!
