backing over soft ground or up a hill. Use
it as follows:
1. Place the brake lockout into the slot be-
hind the roller pin on the side of the ac-
tuator.
2. Slide the brake lockout completely for-
ward in the slot. A washer will keep the
brake lockout from falling out while
backing up.
When pulling the trailer forward and the
actuator extends, the brake lockout should
fall out of the slot. This ensures that the ac-
tuator will function when stopping.
The brake lockout bracket must be re-
moved before towing or the trailer brakes
will not work.
Manual Brake Lockout for Tie Down
Actuator:
If the trailer needs to be moved while in
reverse and without electrical connections
to operate the reverse lock-out solenoid, the
safety pin can be used to manually keep the
coupler from applying pressure to the mas-
ter cylinder. Place the pin in the hole just in
front of the actuator housing. Remove the
pin IMMEDIATELY after backing up and
replace in the coupler position to lock the
coupler. Failure to do so will cause the loss
of brake power when the trailer is towed.
The safety pin when placed in front of the
actuator housing must be removed before
towing or the trailer brakes will not work.
Manual Bleeding of Brakes
The following procedure should be per-
formed only by skilled mechanics. Master-
Craf recommends that it be completed by
an authorized MasterCraf dealer.
Check that all hydraulic ttings are se-
cure. Read and understand all instructions
before starting. Two people are required for
manual bleeding.
1. Remove the master cylinder reservoir
plug and ll the reservoir with brake u-
id. Use either DOT 3 (preferred) or DOT
4 automotive brake uid. DO NOT USE
DOT 5 BRAKE FLUID. DOT 5 FLU-
ID WILL DAMAGE THE SEALS IN
THE ACTUATOR AND CALIPERS
CAUSING FAILURE OF BRAKES
THAT COULD LEAD TO INJURY
OR DEATH. (See Recommended Brake
Fluid information in this section of this
Owner’s Manual.) Follow the instruc-
tions on the brake uid container. Avoid
shaking the brake uid container, and
pour uid slowly to minimize air entrap-
ment. Let the uid in the reservoir stand
until it is completely free of air bubbles.
2. IMPORTANT: Before bleeding the
brake lines, bleed the actuator master
cylinder. Insert a screwdriver through
the hole in the side of the housing and
use short strokes to pry on the push rod
(while holding the safety release bracket
up) until no air bubbles are seen coming
from the small orice hole in the bottom
of the master cylinder reservoir.
3. Start the bleeding procedure on the
brake farthest from the master cylinder.
