3. Release the lock pin and make sure the pin fully en-
gages the attached tongue bracket.
Be sure dirt, sand, ice, etc., does not obstruct
the proper seating of the lock pin.
4. When raising or lowering the jack, prevent the caster
from rotating while cranking. Make sure the jack is
planted on a firm and level surface before unhitching
the trailer.
To prevent personal injury or damage to the boat
and trailer, observe the following:
• NEVER pull on the lock pin when any trailer
weight is on the trailer jack.
• DO NOT move the trailer when resting on
the swivel jack. Use towing vehicle to move
the boat and trailer.
• Keep body and feet clear of trailer tongue
when raising or lowering jack.
Always remember to swivel jack to the horizontal posi-
tion before towing the trailer. Damage to the caster and
jack may result.

E. Surge Disc Brakes
Surge disc brakes are available on trailers manufactured
by Four Winns. Surge disc brakes operate automati-
cally when the tow vehicle’s brakes are applied. When
the tow vehicle slows down or stops, the forward mo-
mentum or “surge” of the trailer against the hitch ball
applies pressure to a master cylinder in the trailer cou-
pler. The master cylinder supplies hydraulic pressure
through the hydraulic system which activates the trailer’s
disc brakes. See Figures R5 and R6. Please refer to
the manufacturer’s literature included in your owner’s
packet for further details regarding operation and main-
tenance.
The benefits of disc brakes in comparison to drum
brakes:
• Fewer moving parts.
• Longer life due to fewer moving parts.
• Friction pads are easily accessible.
• Easy access to caliper for cleaning and
maintenance.
• Calipers are self-adjusting allowing smoother
braking operation.
• Braking performance less likely to be
affected by dirt, water, or rust contamination.
• Fade resistant.
