Q: Brake Problems (2 wheel drive) on 2001 GMC Sierra 3500

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Brake pedal goes to the floor when applying. I have new rotors and pads all away round the truck, new master cylinder, but the brake pedal still goes to the floor when applying the brake.

Everything - including the master cylinder itself - needs to be re-bled. Start with the master cylinder - bench bleed it. Then bleed each wheel. Then repeat each wheel to be sure.
Already bleed brakes and master cylinder quite a few times and pedal still goes to the floor when applying the brakes.
