Cleaning of Actuator Housing

E. Cleaning of Actuator Housing (Omit if Actuator was Replaced)

Use a suitable, clean container to drain brake fluid and contaminants in the following steps:





1. Flush all (3) reservoir ports of the actuator housing with clean brake fluid, (Figure 22), allowing the fluid to overflow and float out contaminants. Wipe the ports with a clean lint free cloth until all particles are removed.





2. Squirt clean brake fluid into the secondary outlet port (Figure 23) and allow the fluid to flush through the housing and flow out the open end.


3. Use the long handled cleaning aid and lint free cloth from the parts package to wipe down the interior of the housing, (Figure 23). Wipe around the entire circumference of the bore and work any particles toward the open end of the actuator.

4. Repeat the flushing procedure through the secondary outlet port.





5. Insert a regulated air nozzle into the orifices in all three reservoir ports, (Figure 24), and blow to ensure that these passages are free of obstruction.


6. Repeat the flushing procedure through the secondary outlet port as needed until the fluid exiting the housing is clear.
