Brake Problems.

[Clutch1819]

i have a 98 gmc z71. my brakes got to where i had to pump them for them to work. well i knew the front rotors were shot so i replaced them along with pads and rear shoes. also got a new master cylinder. pumps up fine when i was bleeding them. no air is coming out now and when you crank the truck, pedal hits the floor. no brakes. so i ended up bleeding them 3 times. no air at all and i still have nothing. any ideas?

Did you bleed the master cylinder first? then bleed the lines starting from closest to farthest? You probably just did not bleed it correctly.

Could be air in the ABS module/pump.
