brake issues, help me get my car driving

The bleeders are up to , trust me I checked a bunch of times hah . I've gravity bled it , I've used the pump thing that connects to the compressor and bleeds it . And I bled it with my friend also . I've heard that there might be some stubborn air pockets that are trapped in the system , that I just can't get out . One of my friends said to tap the calipers with a rubber mallet while bleeding . I was gonna try that . But I figured that I would ask on here and see if maybe my master was to small/ big or the stock distribution block was not good for disk brakes
