    I thought I would throw this out to the list. I did a complete brake 
job on my 61 Rampside. New lines, cylinders, shoes and master cylinder 
rebuild. My dilemma is that  if I drive a distance of say twenty miles 
or more the brake pedal becomes rock hard and the brakes start to lock 
up on all four wheels. I am inclined to think that the issue is in the 
master cylinder. I backed the concentric pedal bolt so that I have 
maximum pedal travel to allow the piston to fully return. I backed the 
shoes off to zero adjustment. These are manual adjusters, not auto 
adjusters and still have this problem. I have bled the system repeatedly 
and to no avail. What am I missing here? I've done numerous brake jobs 
in the past with never a problem. I am using DOT 3 brake fluid not 
synthetic
  ANY THOUGHTS?

Thanks in advance, Mike Emanuele
