D. Surge Brakes & Coupling Assembly
Surge brakes are standard on the SL series 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 hydraulic 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 a padlock must be inserted completely in the
forward coupler latch hole. See Figure S6. This helps
ensure the coupler’s latch remains in the locked
position during towing of the trailer. Refer to Section
S-3 Operation for addi tional information on couplers
and hitching to the tow vehicle.
NOTICE
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
Four Winns® trailers.
DO NOT use a trailer hitch with moving parts.
The brakes could activate when traveling
