Replying to Fks binding problem

Hey guys, one of my heel pieces on both sides of the assembly has some play where the brake assembly connects to the actual metal plastic spring assembly that holds your boot in. It’s right between where the DIN assembly connects to the brake assembly arms right beneath the forward pressure screws. The whole din assembly actually wiggles and has a bit of room as if you were to be able to tighten the forward pressure screws in more...but not the actual forward pressure since that adjusts lower on the arm if that makes sense.
