System Component Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The drum brake system consists of the following:
- Drum Brake Shoes
-
Applies mechanical output force, from hydraulic brake wheel cylinders, to friction surface of brake drums.
- Brake Drums
-
Uses mechanical output force applied to friction surface from drum brake shoes to slow speed of tire and wheel assembly rotation.
- Drum Brake Hardware
-
Secures drum brake shoes firmly in proper relationship to hydraulic brake wheel cylinders. Enables sliding motion of brake shoes needed to expand toward friction surface of drums when mechanical output force is applied. Provides return of brake shoes when mechanical output force is relieved.
- Drum Brake Adjusting Hardware
-
Provides automatic adjustment of brake shoes to brake drum friction surface whenever brake apply occurs.
