aCtuator maintenanCe
The actuator is the mechanism that activates the trailer’s
brake system and is also where the coupler is attached
(See Figure 20). Maintenance of the actuator depends on
the type that is used on your trailer.
Figure 20. Trailer Actuator
Periodically check the actuator mounting fasteners for
damage or loosening. Inspect the actuator for worn or
damaged parts. As you are towing your trailer, be aware
of any changes in braking quality. This could be an early
warning of brake or actuator malfunction and requires
immediate attention. Consult a certified brake specialist
to make necessary adjustment or repairs.
Hydraulic actuator
A hydraulic actuator (Figure 21) changes fluid power
into mechanical power. Therefore, the fluid level must
be checked frequently to assure that the brakes function
properly.

warning
Failure to maintain proper fuel level in the actuator may
result in loss of braking action which could cause severe
property damage, injury or death.
electric Brake adapter
If your trailer is equipped with electric brakes, an electric
brake adapter serves as the mounting platform for the
adjustable channel and coupler. There are no moving parts
on the adapter. Except for periodic visual inspection of the
fasteners, channel and channel bolts, no other maintenance
is required (Figure 22).

adjustable Channel
Your trailer may be equipped with an adjustable channel
(Figure 23) that allows the coupler to be raise or lowered
to a desired height. Periodically check the channel bolts
for damage or loosening.

An improperly fastened coupler can cause the trailer
to disengage resulting in property damage, serious
injury or death.
Be sure the fasteners are tight before towing the trailer.
