Loosen the adjusters on rear of backing plate with a 5/8 inch socket, 2 each wheel. Insert 3 fair sized pry bars between drum and backing plate at about the 2, 6 and 10 o clock positions. Using a Big Hammer, drive the pry bars in and the drum should move. At all costs, DO NOT DESTROY the drums, they are very difficult to replace. Sometimes unbolting the wheel cylinder will help give some more room. Good Luck. Jerry
