Wheel Lugs; Brakes-Electrical - venture SPORT TREK Owner's Manual

Your coach may have "ULTRA LUBE" method of having a grease fitting
in the end of axle. Remove rubber cap on the end of the axle and use a
standard grease gun to place 6 to 8 shots of grease into the bearings, if
needed, before leaving on trip. Don't forget to repack bearings as per
maintenance manual with correct wheel bearing grease.

Wheel Lugs

When the wheels are installed on your recreational vehicle, the lug nuts
must be tightened at 90-120 foot pounds of torque. Powder coat painted
wheels may require more torque attempts due to thickness of paint. You
must re-torque the wheel lugs at 50 and 200 miles. A decal on the wheel
may require torque earlier.
After your first trip, check the wheel lugs periodically for safety. The wheel
lugs should then be checked after winter storage, before starting a trip or
following extensive braking. The size of bolts or nuts is 13/16 inch
standard and 3/4 inch for chrome nut. Over torque will damage
components especially if torque wheel lugs goes over 150 pounds.
Normally the "nut" fails first, however, the embossing on the wheel
can also be flattened, and then fail to keep the wheel tight.
Brakes—Electrical
Electric brakes on your recreational vehicle are designed to work in
conjunction with the hydraulic brakes on your tow vehicle. This means to
have the best brake performance on both systems, the trailer and the tow
vehicle must perform and operate together. Any attempt to use either the
brake system alone, tow vehicle or trailer will cause accelerated wear and
damage.
A brake control is required to operate brake system, which is mounted
under the dash of your tow vehicle, using 12-volt DC power. Electronic
type is used most widely. Each brand has their own operating
instructions.
Battery in the tow vehicle is the primary source of power to operate the
brake system in towable trailer. Keep battery and charging system in
good working condition to ensure available power when required.
Power from battery is sent to the controller, the switch, to provide the
correct amount of current to brake assemblies on the coach. As you press
harder on the brake pedal, more current will flow, applying brakes more,
increasing braking capability.
Wiring to operate your brakes must be sized in both vehicles, suggesting
a minimum of 14 gauge. Your camper has 14 gauge from front end to
brakes. Brake assemblies are wired in parallel, never in a series. Being
parallel, there will be equal voltage and amperage at each brake
