hoses. The master cylinder should be filled within
1/2 inch from the top of the reservoir.
At the beginning of each year, inspect the brakes for
excessive wear, have linings replaced if necessary.
If the brakes need bleeding, consult your Four Winns
dealer for assistance. If unavailable, a brake or auto
repair facility can perform the repair.
Refer to the manufacturer's literature included in the
owner's packet for additional information on the brake

J. Bearings

Wheel bearings and seals should be inspected at the
same time as brakes. Have worn or defective parts
replaced. Grease bearings and seals at this time and
at the end of the boating season. Bearing Protectors
should be greased three to four times a year. A
grease fitting is provided.
Four Winns uses the Accu-Lube™ bearing protection
system on its trailers. The Accu-Lube™ design is
submersible and provides for grease flow that com-
pletely repacks and protects the bearings. This
lubrication system disallows water entry, thus extend-
ing the life of the bearings, spindle and hub.
Lubricate the bearings as follows:
1. Remove the rubber plug.
2. Insert the grease gun into the grease fitting.
Pump grease until old grease comes back
out the front.
3. Remove old grease and reinstall rubber plug.
Most bearing failures are due to improper
maintenance. Be sure to inspect bearings and
seals as noted in Section S-B and refer to the
manufacturer's literature included with your
trailer.
