This video goes over the repair / replacement procedure for the rear drum brake wheel cylinder on a old body style (OBS) GM truck. The vehicle shown is a 1999 Chevrolet 2500 class 3/4 ton truck with 13" rear drum brakes, but the the approach would be similar for all GM truck models of the mid to late 1990s (1994 1995 1996 1997 1998 1999 2000) across Chevrolet, GMC, and Holden. So Cheyenne, Suburban, Silverado, Sierra in the C/K 2500 and 3500 range would likely have this style of rear drum brakes. The wheel cylinder is the same part number for either side of the truck.
