Now that winter is here, road salt must be washed off new galvanise after every trip to prevent it from salting. When the trailer is about one year old and the frame has turned to a dull grey the finish is better protected.
The rust protection is not compromised if salting occurs, but the galvanise can look un-sightly if not looked after when new.

The following schedule is recommended to keep the trailer in good condition. Maintenance
requirements will vary depending on the circumstances in which the trailer is operating.
After the first 500 miles the brakes must be adjusted at the hubs to allow for initial bedding
in. Failure to do this will permit the hitch damper to travel excessively and overheat causing
premature failure which cannot be covered by our warranty.
Each 500 miles or 800 km:
1. Check the operation of the lights.
2. Check the tyre pressures.
3. Check that the wheel nuts are tight.
4. Check for missing hub grease caps and inspect for any damage.
Each 2500 miles or 4000km:
5. Adjust the brakes.
6. Lubricate the brake linkages.
7. Check the free movement of the brake cables.
8. Inspect for tyre wear.
9. Grease the overrun coupling and lubricate the jockey wheel.
10. Check the security of the axle and hitch mounting bolts.
Each 5000 miles or 8000km:
11. Remove the hubs and check the brake lining condition.
12. Check, re-grease and readjust tne wheel hub bearings.
13. Inspect the floor for signs of wear, the rear door catches and the general body
1. Jack up the trailer one wheel at a time whilst other wheels remain chocked.
2. Release the handbrake and ensure that the overrun coupling is fully forward and that
the cables and linkages are free and fully retracted.
3. Rotate the wheel forward and tighten the adjuster on the back of the brake plate until
the brakes apply.
4. Release the adjuster until the wheel turns freely forward.
5. Apply and release the handbrake to centralise the braKe shoes.
6. Make any final adjustments required to the brakes.
7. Repeat on the other wheels.
8. The main brake rod adjuster at the back of the hitch should not require adjustment,
but if this is necessary, release the lock nuts and adjust the linkage until there is 1mm
of play between the hitch draw tube and the main brake operating lever.
9. Check the operation of the handbrake, the brake linkage should retract when each
wheel is rotated backwards and the brakes should reapply.
Most brake adjustment problems and the cause of hubs overheating is usually the flexible
cables being damaged or sticking. If they are not working freely they should be replaced.
The cables should not be greased, this may cause them to stick, but they can be lightly oiled.
How to remove, refit and adjust the hubs.
1. Chock the wheels and release the parking brake.
2. Jack up the trailer and remove a wheel.
3. Slacken the brake adjuster if necessary.
4. With a screwdriver blade inserted between the flange of the grease cap and the hub,
remove the cap.
5. Straighten and remove the split pin from the axle nut.
6. Remove the nut anti-clockwise and draw the hub off, taking care to retain the outer
7. Check the condition of the brake linings and the operation of the brake expander.
Inhalation of brake dust can be harmful.
8. Replace the brake shoes if necessary.
9. Examine the condition of the wheel bearings and grease seal.
10. If the grease is contaminated, wash it out with paraffin and pack the bearings with a
suitable hub grease.
11. Refit the hub and tighten the nut fully.
12. Slacken the nut until it is not applying pressure to the bearing and there is no free play.
Normally about 30 degrees, or one slot in the castle nut.
13. Adjust the brakes as previously described.
How to replace the brake cables.
1. Chock the trailer wheels, release the handbrake.
2. Remove the lock nut on the forward end of the cable attaching it to the balance bar.
Retain the cup washer.
3. Release the locknut securing the cable to the axle beamand release the cable through
the slot in the bracket.
4. Draw the outer cable cover away from the brake back plate.
5. Remove the top half of the cable bracket and unhook the end of the cable from the
6. Refit the new cable in the eyelet, replace the cover and slide the shroud on the cable,
back over the bracket.
7. Reconnect the linkage and adjust the brakes.
