Tie Down's actuators feature a shock dampener that uses brake
fluid from the master cylinder. The dampener must be primed
before bleeding or using trailer. To prime the dampener, fill the
master cylinder with DOT 3 brake Fluid. Push the coupler into the
housing and slowly pull out 3 times, then refill master cylinder.
To pump master cylinder, insert a flat tip screwdriver into the
round hole near the front of the actuator cover. (picture 1)
Screwdriver tip will fit into the slot provided in the emergency
brake bracket as shown. Push the screwdriver forward and back
to pump the master cylinder. (picture 2)
IMPORTANT: Never go past 90 degrees (screwdriver
straight up) when "pumping" the master cylinder (picture
3). Moving past 90 degrees will cause the emergency brake
bracket to "set", locking into place creating constant
pressure in the brake lines. If you find that the screwdriver
will not go in place as shown when starting to pump the
master cylinder, or you move the screwdriver past 90
degrees and feel it "snap into place", you must unlock the
emergency brake bracket as shown in pictures 4 and 5.
Pictures 4 & 5 show the underside of the actuator. If the oval slot
where the emergency brake release tab comes out is "silver"
(picture 5) and the release tab is pushed forward, this indicates
that the emergency stop bracket is "set" and must be released
before bleeding brakes or using the trailer. If the oval hole is
"dark" (picture 4) and the release tab is free to move back, the
emergency brake is ready to go, including bleeding and using
the trailer.

Emergency Brake Engaged Emergency Brake Disengaged
To release the emergency brake bracket, (pictures 6
& 7) insert a brake adjustment tool (looks like a bent
screwdriver) or flat screw driver into the slot on the
release tab (on bottom side of actuator) and pull
down until a "click" noise is heard indicating the
bracket is released.
After bleeding, make sure the emergecy stop is
disengaged (figure 4 & 7).
