Transmission Drum Brake Notes

The shoe set or hardware kit is readily available, just make sure it's for a C3500 with 15K GVW and tail mounted setup. Any of the brands of shoe set need to have the half moon ground out a little or the drum will NOT go back on.

• Raybestos 647PG shoe set
• Raybestos H7399 hardware kit

Rockauto is the cheapest.
