Installation Notes and Tips

Confirm the rear axle application and verify drum measurements before installation. Inspect brake shoes, hardware, wheel cylinders, and parking brake components during service so the new drum is installed on a clean, even braking surface. Measure the existing drum against the discard diameter specification of 251.5 mm (9.9 in.) and replace if the current drum is beyond service limits.
