- Reduced braking consistency at the rear axle
- Noise related to drum surface irregularity

Installation Notes and Tips
Confirm rear axle fitment by year, model, and the listed notes before installation. Measure the existing drum and compare the nominal drum diameter, outside diameter, depth, and lug-hole diameter to verify match-up with the vehicle’s rear brake assembly. Inspect brake shoes, wheel cylinders, and related hardware for wear before installing the new drum, and clean the braking surfaces to remove dust or corrosion.

Verify all dimensions and vehicle notes against the existing brake system to ensure correct rear drum selection for your Mitsubishi Galant, Cordia, Tredia, or Dodge Colt application.
