CHEVROLET TRUCK BRAKES PROBLEM

1971 Chevrolet Truck • 123,755 miles

We have replaced all brake lines, mc, powerboster, we adjusted the brakes. When we start the truck the brake pedal goes to the floor, when we unhook the vacumn hose we have manual brakes. How do we fix this problem?

You still have air in the system. Re bleed the system
