It may be helpful to disassemble and assemble one wheel at a time so that you will have an example to refer to while you are installing the shoes.
The brake pedal must not be depressed while the drums are removed.
Since the actuator, pivot, and override spring are considered an assembly it is not recommended that they be disassembled.
If the linings are to be reused, mark them for identification.
A small amount of fluid will be present to act as a lubricant for the wheel cylinder pistons.
The coils of the spring must not be over the star wheel. Left and right hand springs are different do not interchange.
CAUTION It is important to keep your hands free of dirt and grease when handling the brake shoes. Foreign matter will be absorbed into the linings and result in unpredictable braking.
