Have you tried bleeding your brakes, that sounds more like what you're dealing with. The front pressure should be higher than the rears.

thx elwesso for reply me ur correct front should be more then back side but car brake not strong from back side i don't know why i must push to last level to be strong brake and i also chk if there is air with oil in pipe but no air

Typically the master cylinders are OK unless they leak, I'm not sure I've ever head of one being messed up causing inadequate braking to one axle? When you were bleeding the brakes did you ever let the fluid ever get to the point where it sucked in air? If you get air in the system there, it's really tough to get it out.

100 % there is no air with oil inside pipe but also one more thing when u push brake its not soft its like hard i know i can feel booster its ok but also brake not good only back side u have to push strongly
