I replaced master cylinder and bleed all bleeders. why are the brakes still having problems? And there are no leaks in the line.

it may be the ABS has air in it. if so a mechanic has to put a scanner on it to command open valves so it can be bled. you might try renting a power bleeder and bleeding system.
