Hello there
I need some advice about my car brakes I have a soft pedal that drops all the way down to the floor & at times will not pull the car to a stop, if I press the brakes firmly I have the opposite reaction it wants to through me out the front window. I have changed the master cylinder bleed the air out of the lines adjusted the brakes machine the front drums I have no leaks what so ever & I do not want to convert to disc brake

Can any one tell me if this is happing because the drum brakes are worn to far or may be the front wheel cylinder are not working to good

Any advice would be grateful
Thanks Rob
