In this review the Power Stop B855 rear Autospecialty brake shoes are evaluated primarily for owners of 2005-2008 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks with rear drum brakes. The bottom line: these are a practical, value-oriented replacement that deliver improved stopping performance and quiet operation for drivers who want a direct-fit drum shoe without complicated modification. Fit and braking performance are the strongest reasons to consider them, while customers should confirm fitment with the tool provided before ordering.

Key Features

• Bonded, semi-metallic construction: provides increased friction and consistent stopping power compared with older organic linings for heavier truck use.
• Post-cured for faster break-in: reduces the time needed to reach optimal braking performance after installation.
• Precision arc ground: ensures the shoe contour matches the drum for a snug, reliable fit that helps reduce uneven wear.
• Asbestos free and new steel backing: offers safer materials and avoids reusing worn components, giving longer service life when installed correctly.
• Application specific fit: designed to fit listed 2005-2008 Silverado and Sierra 1500 models with rear drum brakes, simplifying installation for compatible trucks.
