Okay. Just trying to confirm the progression. You replaced the pads and calipers and the fluid was low at that point? Then you bled the brakes and it was still soft. Then you start the engine and it still feels soft but it will be firm when the engine is off?
If this is the case, you may still have air in them. I would suggest starting over and bleeding the master in the vehicle. You do this by taking the lines off and routing lines back into the mater and then pump the brakes. If you get a bleeding kit then it will have clear lines so you can see if there are any bubbles coming out but you just pump it until you see two or three in a row where it is solid fluid. Then reconnect the lines and bleed all of them again. Starting with the right rear, left rear, passenger front, driver front.
Also, when you have the lines off and after you bleed the master if you want to confirm it is ok and there are no leaks internal to it, just cap the lines with bolts and press the brakes. You should have a hard pedal. If not then you need to replace the master. Just make sure you use bolts that are the same length or shorter then the threads on the brake line nuts. Otherwise you could crack the master then it needs to be replaced.
Let me know if you have questions on this. Thanks
