2002 Chevrolet Suburban Brake lights

I have a 2002 Chevy suburban 5.4 V-8 with a factory tow package and this past weekend my brake lights would not go off unless I disconnected the battery so I replaced the stop lamp brake switch on the pedal and it still will not go off I thought that would fix it seeing as my cruise control does not work anymore but did the day before the lights stayed on any suggestions on something else to try
