1996 GAS K1500 Brake problem

We changed pads and shoes. We never disconnected anything.

When we put everything back together we lost pedal when we started the truck.

We have pedal with the Suburban NOT running. As soon as we start the truck we lose the brake pedal.

It acts like air in the lines. But we never opened anything up to allow air to get in the lines.

We bled the brakes anyway and got no air.

We then changed the master cylinder and it is still acting exactly the same.

We checked the wheel cylinders and they are dry. We see NO leaks.

Any ideas would be appreciated

How did you compress the brake piston back into the caliper?

If you don't adjust rear shoes until they lightly drag the drums you won't have any pedal.

We used a C clamp with the reservoir open.

Turned out we did not have the system properly bled. Never had that problem before. A tube ran from the bleeder into a can of brake fluid was the fix
