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.
