When I changed rear pads and rotors on 2001 S10 blazer I lubed all the pins and the brakes seem to be to tight and smell hot after test drive is this normal?

Hard to say. When burnishing in new pads, you should make 20-30 stops on flat roads going from 25 mph to a stop and allowing time for the rotors to cool as needed. A burning smell is not necessarily abnormal however.
