What It Helps Fix

Installation Notes and Tips
Verify the drum diameter, bolt circle, hub register, and mounting hole dimensions before installation. Measure the existing brake drum and inspect the shoes, wheel cylinders, and hardware for wear before reassembly. For best results, clean the friction surface and confirm the drum seats evenly on the hub.
When searching for a rear brake drum for Honda Civic or Toyota Corolla applications, confirm the vehicle’s brake configuration against the listed dimensions and service requirements. Part number 122.34001 should be matched to the correct OE-style drum brake setup before installation.
