2007 f250 brakes go to the floor and is hard all new brakes changed one caliber bled brakes every thihg looks good

You may still have air in the ,lines.if you want to do it properly you must bleed all four wheels till the brake fluid is clear and free of air. when you complete this task,you should have a nice hi pedal,if not check for leaks.if no leaks,your problem may be the master cylinder. make sure your master is full at all times during the bleeding sequence.to check the master start the vehicule,press the brake pedal and hold down there should not be any downward travel on the pedal,if there is replace the master.

If you replaced the rear brake shoes check the e brake adjuster to make sure it is adjusted/ installed properly. also check that the rear wheel cylinder is in proper contact with shoes
