Already replaced break booster, master cylinder, 2 wheel cylinders, checked the brake calibers and all the lines and the brake pedal still goes down to the floor. Please help me with any suggestions of what it could be. Anything will be greatly appreciated.
Not bled properly. Redo it.
does it have abs ? or a r.a.b. valve?
if you replaced all the parts, did you bleed the brakes FULLY? and in the right order? depending on whether the brake system is a cross based system or a front-rear system the corners come in a different sequence. if it is a front-rear system then you need to start in the back on the passenger side, then go to the driver rear, then the passenger front then lastly the driver front. that way you chase all the air away from the master cylinder and get the brake system completely bled to prevent the pedal from sinking to the floor and feeling spongy
