I purchase the black magic rotors and break pads for the front along with new calipers. Should I do the back brake pads? I don't have the money to do the rear is that stupid of me to do the front first. I hear squeaking every time i brake and I never changed the breaks . Doesnt a jeep break from the front should i just switch the rear brake pads with AutoZone shit for now or just leave them please help!!! I purchase the front shit already
