Cleaning of Parts
1. U se denatured alcohol to clean thoroughly all m etal
brake parts. B low out all passages, orifices and valve holes.

U se o f gasoline, kerosene, anti-freeze alcohol or any
other cleaner w ith even a trace o f mineral oil w ill
dam age rubber parts.
D irt is the major cause o f trouble and wear in service.
Be sure to keep parts clean. R e wash at reassembly if there
is any occasion to doubt clea n lin ess-su ch as parts dropped
or left exposed for eight hours or longer.
Inspection and Replacement of Parts
1. Inspect all rubber parts. W ipe free o f fluid and
carefully inspect each rubber part for cuts, nicks or other

flow and should account for the majority o f troubles
traceable to leakage. In case o f doubt, install new parts for
safety.
2. Inspect in accordance w ith Inspection Table: (The
table is organized by power brake unit groups.)
G E N E R A L A S S E M B L Y
Be certain that all rubber parts are clean at reassembly.
