After disassembly, immerse all
metal parts in a suitable solvent. Use
only alcohol on rubber parts or parts
containing rubber. After the parts
have been thoroughly cleaned and
rinsed in cleaning solvent, the metal
parts which come in contact with
hydraulic brake fluid or rubber parts
should be rewashed in clean alcohol
before assembly. Use an air hose to
blow dirt and cleaning fluid from the
recesses and internal passages. When
overhauling a power booster, use all
parts furnished in the repair kit.
Discard all old rubber parts.
Inspect all other parts for damage
or excessive wear. Replace damaged
or excessively worn parts. If the in-
side of the booster shells are rusted
or corroded, polish them with steel
wool or fine emery cloth.
