1: HELP - Brake Drum Illustration (#1)
This illustration depicts the typical GM rear brake system found on passenger cars equipped with 9.5, 11, or 12-inch rear drums, including models like Firebird, Camaro, Chevelle, and GTO. Specifically, it shows the rear brake drum from a 1979-81 Firebird or Camaro, though most designs follow a similar layout.
Note that the wheel cylinder is positioned in the upper center area—use this as a key reference point when recalling the system’s configuration.
