Hi friends,
I am completing full replacement of my brake system, new lines, shoes, Master Cylinder, brake wheel cylinders and drums. After bleeding the lines and releasing the pedal, the fluid will not flow back into the cylinder leaving the wheel cylinder pistons extended. I have checked the brake lever to firewall measurement as described in the shop manual and it is OK.

What could be causing this?

Regards, joe
