Brake problem?

This Year My 94 Dakota Loss All Brakes. Changed Calipers And Bled All Lines. Still No Brakes. Talked To The Garage And They Told Me That Dodges Were None Too Take Forever To Bleed. So I Bled Them Each Side 15 Times. You Would Not Believe After The 7 Or 8 Time I Bled Them The Air Started To Come Out. My Brakes Are Fine Know. So Bleed And Bleed And Bleed. Took Two Cans Of Brake Fluid But That Was Cheap Enough. Good Luck.
