Ford Model A - Modification Front Brake

This is the brake wedge with the wedge stud and they can normally not float from side so side.

Here you can see the mounted wedge on the bottom of the picture.

On the left hand side you can see the original wedge and on the right hand side the wedge floater kit. The floater kit allows the wedge to float, so both brake shoes will be pressed with the same pressure to the brake drum and this gives you a better brake.

Here you can see the difference, the stud on the right is smaller. You don't have to make this modification yourself, Snyder's or Bratton's do have this item on stock.
