What It Helps Address

• Rear brake pulsation caused by worn drum surfaces

• Reduced braking consistency from heat-worn or corroded drums
• Fitment issues when replacing an OE-style rear drum
• Service needs on rear drum brake systems for Mazda, Ford, and Mercury vehicles

Installation Notes and Tips

Verify drum diameter, bolt pattern, hub register, and rear axle application before installation. Confirm the vehicle uses a rear drum brake setup and compare the existing drum dimensions to the specifications listed for Centric 122.45018. For best results, inspect brake shoes, wheel cylinders, and hardware condition during service so the new drum seats evenly.
