Re: 1972 K2500 no rear brakes
Success! I went back to square one. Pulled the master cylinder to verify it was not leaking out the back. And while it was out of the truck I bench bled it. Yup it had air in it. I also made a proper tool to hold the pin at the front of the combination valve. Checked all connections to make sure they were tight and then bled all 4 corners. Brakes work great and no red light!
Had so much time left today that I replaced the drag link and tie rods ends. Still had the original one piece drag link.
Now it stops well, steering is tight and it tracks nice and straight.
A good day!
