CHECKING THE AIR CAN SLEEVE RETRACTION
The SAAR brake’s air can sleeve must be positioned correctly for safe operation.
If the air can sleeve is not in the correct location, use a wrench and loosen the nut as
far as you can. The sleeve will drop down as shown in Figure 23. Check all four air
cans.
Note: Verify that the brakes are operating properly before replacing the covers
and using the dyno.
