to see if the ground wires as well as other wires are in contact. If all wiring checks out all right, remove
the wheel and drum and see if the wiring inside of tire wheel is intact. Check the magnetic actuator for
excessive wear. By using a steel object, check the magnet when applying the hand lever in the tow
vehicle to see that a strong magnet exists. If not, replace magnet actuator. Adjust brake shoes every
10,000 miles or six months as described above.
The wheel beatings should be inspected and repacked with a good grade of wheel bearing grease every
six months. Inspect all wiring and lights and replace when showing wear or damage.
Caution:
After hooking the trailer to the towing vehicle and before driving away, check closely the
following:
1.
Trailer hitch to see that latch is closed and the safety pin is in position. Check to see that the
trailer will not come off ball by lifting trailer with trailer jack. Balls and hitches wear and should
be replaced when slack shows.
2.
Electrical connectors: “pig-tail” is connected to tow vehicle.
3.
All lights are working properly.
4.
Brakes are working properly. Move trailer slowly and depress tow vehicle foot pedal to see that
trailer brakes lock.
5.
Inspect tires for wear. Check tire pressure. Inflate tire to 65 PSI. Under inflated tires run hot and
may blowout.
When connecting the trailer to truck, extreme care should be taken to prevent running into the trailer hitch
and jolting it hard as this will cause the plunger that goes into the master cylinder to bend and bind
causing the master cylinder to stick and not completely release brakes. This will cause the brake shoes to
wear and heat. The heat can cause a tire to blow-out and ruin both tire, brake and drum.
