Applications and Problem Solving

• Brake fade from overheated or warped drums
• Corrosion or physical damage to the original brake drum

Installation Notes and Tips

When installing the Centric C-TEK Standard Brake Drum 123.68003, ensure the mounting surface and hub are clean and free of debris. Verify the bolt hole pattern matches the vehicle’s specifications, specifically a 5-bolt pattern with a 5.5-inch bolt circle diameter. Measure the hub hole diameter to confirm compatibility. Since this drum does not feature outer cooling fins, adequate ventilation should be maintained through the vehicle’s brake system design. Always check the maximum brake diameter (discard) to determine if replacement is necessary.
