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.

injury or death.
Be sure the fasteners are tight before towing the trailer.
