On them, the bottom of the shoes are solidly held against a pivot point, and only the tops of the shoes expand out to contact the drum. This design has less braking ability than a duo-servo type brake because only one shoe has a self-energizing effect. In this setup, the front (leading) shoe may be the same as the rear (trailing) shoe as far as the amount of friction material covering the steel backing shoe, but the material may be thicker on the front (self-energizing) shoe. In other cases the front shoe will be smaller like the duo-servo type. |
