Default 2004 2500HD silverado brake issues

I have just replaced my front calipers, pads, and rotors on my trck and I am still having issues. I couldn't get the passenger side to stop leaking so I got a new rubber line and replaced it. it stopped the leak so I bled the brakes and had a great pedal. I went to go somewhere a day ago and driving down the road the pedal would go to the floor but I could still stop. Then went to go somewhere else and then had a great pedal again. I'm thinking bleed them again or master cylinder...Any other suggestions?

Pump the brake until you have pressure, and then keep pushing down on the brake pedal and hold constant pressure. If the pedal continues to drop you probably need a master cylinder. If you have to pump a few times to get the pressure, it definitely wouldn't hurt to bleed it some more.

Shouldn't need a new master cylinder on an 04.

Double check for leaks.

If your fluid got too low you might of got air in the abs module. If you did it needs to be bleed with a scan tool.

You would have to bleed it with the scan tool. Then bleed them normaly to get it all out.
