I'm confused why KF would form a solution with a pH greater than 7 but then KBr's solution is still neutral.

F is an exception to this rule, in that F is the only halogen that does affect the pH of a solution. Since KF is a very weak acid, the conjugate base of KF is a basic solution, therefore producing a pH greater than 7.
