72 dart disk brakes

[orange72dart]

I am doing a disk brake swap, all the parts came from a 73 duster,upper a arm,spindles,rebuilt the calipers,installed a rebuilt MC,new hoses, new lines bleed the system with a power bleeder and the old fashion way. no peddle if i pump the peddle i get just a little but goes away fast. o ya i did install a port valve for the rear brakes. is the rod the wrong lenght?,bad MC need help thanks

Did you bleed the master? If not, loosen one line at a time (slightly) and push pedal, many times. If that doesn't help, see if light is on ( switch is off center). Then check for leaks.
