D. Surge Brakes & Coupling Assembly
Surge brakes are standard on the SL model trailers
manufactured by Four Winns. Surge brakes operate
auto mati cally when the tow vehi cle's brakes are ap-
plied. When the tow vehicle slows down or stops, the
forward momentum or "surge" of the trailer against
the hitch ball applies pressure to a master cylinder in
the trailer coupler. The master cylinder supplies hy-
draulic pressure through the hydraulic system which
activates the trailer's disc brakes. See Figure S5.
Please refer to the manufacturer's literature included
in your owner's packet for further details regarding
operation and maintenance.
To hitch the trailer to the tow vehicle, place the cou-
pler latch in the open position to unlock the coupler.
See Figure S5. Push down on the coupler latch to
lock the trailer to the ball hitch. Push coupler latch
lever back until the latch engages and is properly
seated. The safety pin, provided with the trailer, or

coupler's latch remains in the locked position during

the tow vehicle.
Anti-sway devices as used on recreation al
vehi cles (RV's) are not applicable to surge
brake systems and should not be used on
