Braking issues

I'mhaving big problems with new 4 wheel drum brakes, brakes have been bled,but now car pulls to right when driving, but straightens out while braking, then for a while brakes feel good, then while braking from 40mph I put the brakes on and pedal feels like it drops and brake light on dash comes on and of course takes for ever to stop,then they heat up and start squeaking when brakes applied,it has a rebuilt power booster all new wheel cylinders,drums and shoes.but the master cylinder I think...
