Brake Actuator and Coupling Assemblies.
E. Surge Brakes
Surge brakes are available on certain model trailers
manufactured by Four Winns. Surge brakes operate
automatically when the tow vehicle’s brakes are
applied. 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 brakes. See Figures S-5 and S-6.
Please refer to the manufacturer’s literature included
in your owner’s packet for further details regarding
operation and maintenance.
