An apparatus for a drum brake assembly having a brake drum and an actuator includes a shoe spreader web with a first side for connecting to a first piston of the actuator and a second side for connecting to a second piston of the actuator. A first brake shoe is secured to the first side of the web. A second brake shoe is secured to the second side of the web. The brake shoes have a first condition in which the respective first and second sides of the web move the brake shoes to apply braking force to the brake drum in response to actuation of the actuator. The first brake shoe has a second condition moving relative to the web for absorbing brake drum contraction forces and prevent the full magnitude of these forces from reaching the actuator clevises.
